1 2 3 4 5 6 7 Powerbox-Systems Without a Powerbox-Systems has established themselves as the world leaders for powerboxes and electrical components in this wonderful hobby. Their product range is vast and for a large variety of models, however aimed mostly at the top end of the spectrum, for large models with complex guidance systems, such as large scale aerobatic models, fast and scale jets, large gliders or ultra precise F3A models. One of my first sponsors, their products control every aspect of flight for our models. With powerboxes that are completely redundant, twin power and completely programmable, gyros, ignition switches, light systems, smoke pumps and so many useful accessories such as special wires or adapters. With Powerbox-Systems I made my first trip to another continent, specifically to Tianjin in China (close to Beijing) in the year 2015. An unforgettable experience, just like so many others that I have had with Powerbox-Systems in recent years, such as the trips to Anji (China), Santiago (Chile) or Ahmedabad (India) Below you will find practically the entire Powerbox-Systems range, as I have been lucky enough to fly for them for many years, having tried all their products and even collaborating with the design and testing on a number of them.

We had the good fortune to meet the owner of the company, Mr Hacker who was also at the competition over the weekend. Very proud of their products, we were shown their products and brands that they deal with, as well as some of their latest motors and their models. Here we can see the A200 brushless motor, which is designed to power 3m aerobatic planes, with good authority and power similar to that of a 170cc petrol engine. During the competition we were also able to see their A150 (equivalent to a 120cc engine) powering Krill’s new Yak 55M with great performance which was used by Mark Leesberg to complete an amazing freestyle. In this particular model they were using 4 6S 5.000mAh lipo packs, also Hacker of course. In their exposition they also had the C50 quad, which as its name implies, is made up from 4 C50 motors, which through their clever gearbox power just one central propeller, able to produce enough power to successfully fly the largest of 3m aerobatic planes. It is interesting to look at how even inside the company they have changed the technology used, advancing and being able to obtain the same power from their new A200 as they could previously with the 4 C50’s. In their exposition, they also had their own models, such as Sebastiano Silvestri’s 3m electric Krill-Model Katana, as well as EDF jets, electric scale models and various medium sized electric aerobatic models. Durante nuestra estancia en Alemania para el German Acro Masters, aprovechemos para visitar también la fábrica de Hacker-Motor en Schinderstraßl. Además tuvimos la buena suerte de poder conocer en persona al dueño de la empresa, el Sr Hacker, un tipo muy simpático quién había estado además en el campeonato. Muy orgullosos de sus productos y marcas que manejan, nos demostraron algunos de los motores más importantes que fabrican al igual que algunos de sus aviones. Aquí podemos ver el A200, motor diseñado para mover aviones acrobáticos de 3m y que se podría comparar a los motores de combustión de 170cc. Pudimos ver en el campeonato además un ejemplo del A150, equivalente a un 120cc, montado en el nuevo Yak 55M de 2.60m de Krill Model, el cual usó Mark Leesberg en su freestyle del domingo con buenos resultados y una potencia importante. En este modelo llevaban cuatro paquetes de lipo de 6S 5.000mAh, de Hacker cómo no. Además tenían en su exposición el predecesor del A200, el C50 Quad, el cual como su nombre indica está formado por 4 motores C50 los cuales mediante una reductora hacían mover una hélice central con la potencia necesaria para mover un 3m. Es curioso ver cómo va evolucionando la tecnología de esta marca ya que ellos mismos han cambiado totalmente la ideología de estos grandes motores, pasando de usar los 4 C50 a lograr incorporar la misma potencia en una sola unidad. Además en su exposición tenían a uno de los Katana de 3m volado y firmado por su diseñador, Sebastiano Silvestri, (eléctrico cómo no) y luego modelos de todas clases, desde turbinas por EDF, maquetas eléctricas o aviones acrobáticos de tamaño medio.

Conocemos a: Mejzlik Meeting: Mejzlik

Mejzlik Factory visit During our stay in Znojmo for the EXFC, we took the advantage to go and meet the people behind Mejzlik, as well as finding out a bit more about their products. On our arrival, we met with Ales, who very kindly showed us their catalogue of propellors, giving us an overview of their most recent developments as well as showing us their amazing stock in all sizes of propellors. Shortly after this we met with Tomas Mejzlik who was nice enough to dedicate his morning to going over the production, design and development of their products with us. Mejzlik must be most well known for their propellors, so we thought that this was a good place to start. The company currently offer just over 100 different sized carbon propellors designed for sport-aerobatic use, plus an extra 60 “speciality” carbon propellors, normally only produced on demand. A very interesting detail from the production of Mejzlik”s carbon production line is that they use an Epoxy that was specially designed for them, which as well as being stronger than usual, also contains a much higher elasticity than regular epoxy, which allows you to do this to their products without damaging them! As far as the design of the propellors, everyone knows that this is a much more complex procedure than it looks in order to get a workable propellor. Nevertheless, Tomas explained some of the fundamentals to us, showing that he really does know his stuff, in many cases having to repeat himself due to us not being able to keep up! For example, everyone knows that the more pitch a propellor has, as long as it can run at the same RPM, it will have more thrust than the same diameter with less pitch. But seemingly you must also take into account the speed of the model, as a very flat pitched propellor could be dangerous if the model reached a high forward speed, due to the impact force caused by the speed on the “flat” part of the propellor. So low pitch is best designed for slower models, with less forward speed. Mejzlik as well as the standard diameters, also have variations of one same size, such as the Evo, L, S and N. Each with a different meaning and different shape. For example, the Evo has a different leading edge, with an almost straight trailing edge, which was designed to try and reduce some noise levels, while still keeping the prop diameter and power. The L, have less carbon layers for the outer shell of the prop, however with a clever internal structure are more rigid while still being lighter than the usual versions. Meaning less force is needed to spin the prop at the same speed as the non L version, which leads to a faster spin up. We asked Tomas why the centre of the prop was so large (the first half of each blade), and if it would be possible to make it smaller in order to not loose RPM”s. Very interestingly, they have performed tests, and the first 2/3rds of the propellor do not make much to any difference in how the propellor works, it”s speed or it”storque. The “working” part of the propellor being only the last 1/3rd (the tips) Since the recent fever of round cowled models, such as the Sukhoi”s, Yaks… pilots have encountered a new obstacle, which is the cowl “hiding” much of the propellor. Fortunately, as mentioned above, the centre part of the propellor doesnt make much difference, so there is not much loss. This is why moving the engine (or more to the point the propellor) forward, leaving a little more gap between the engine and the cowl works so well, because the 1/3rd of the propellor that generates the power is then still in full working order with clean air flow. Tomas also explained how single blade props are the most efficient. As due to there being only one blade, by the time it does 360º it has clean air again, so uses 100% of its capabilities (approx.) They can”t be used however on large scale aerobatic models for example due to the size of the weight needed to counterbalance the single blade. To calculate what size 3 blade prop we require, they explained that it is simply a case of multiply the diameter x 0,9, and reccomendably increase the pitch by 1-2″. Example: 32*10 2 Blade 32 x 0,9 = 28,8. So 29″ Diameter. 29*10 – 29*11 or 29*12 for 3 blade As well as their propellors, Mejzlik”s slightly less known spinners are of the same quaity, amazingly light weight and with the same perfect carbon finish. Tomas explained how they have a new method of making their spinners, which makes them just as strong, but lighter by forming the spinner both from inside and out. Not only this, but their new series spinners also have aircraft grade aluminium backplates, meaning that they are stronger, allowing more metal to be milled away, making them even lighter. As a reminder, Mejzlik also make other high quality carbon parts such as undercarriages and spats Another interesting part that cought our eye was their electric motor supports, designed to stand all the torque of the motor, assuring a correct and safe mounting Thomas also explained that the new Quad and Octo copters (helicopters with 4 or 8 rotors) have caused a great boom in the market, and they have had to design an entire new line of carbon propellors for these helis. Users have commented on more silent and smooth running, as well as an increase in flight times It was also interesting to find out that Mejzlik have been approached on different occations by companies looking to have special parts made in carbon, and wanting the best possible finish are going to Mejzlik. Just one example could be this part, a specially moulded air intake for the Porsche 911 Carrera! Due to Mejzlik constantly improving their products, they are interested in feedback about their products, along with ideas for improvement or development, as well as constructive criticism, so please feel free to send your comments either to them directly, or email me at and I will be happy to forward your comments on anonymously. In the mean time, Mejzlik have such high quality products, and many of them are often overlooked, why not take a look at their new webshop at: Visitamos la fábrica de Mejzlik en la repúplica checa. Durante nuestra estancia en Znojmo para el EXFC, aprovechamos para visitar y conocer a la empresa Mejzlik, así como aprender sobre sus productos.Al llegar conocimos a Ales, quien amablemente nos demostró toda la gama de hélices que frabrican, dandonos un breve resumen de las últimas tendencias, así como su increible stock en todas las diferentes dimensiones.   Seguidamente, conocimos a Tomas Mejzlik quien nos dedicó toda la mañana para repasar todo el proceso de desarrollo, diseño y producción de sus productos. Mejzlik son sin duda mejor conocidos por sus hélices, por lo que éste fue el sitio perfecto para empezar.  Actualmente ofrecen algo más de 100 tamaños distintos de hélice en carbono para vuelo acrobático, mas otras 60 medidas más especializadas, normalmente fabricadas bajo pedido. Un detalle muy curioso fue que Mejzlik usa un Epoxi diseñado específicamente para ellos, el cual además de ser más fuerte de lo habitual, tambien tiene un valor elástico mucho más elevado de lo habitual, que te permite hacer esto sin romperlos! En cuanto al diseño de las hélices, todos sabemos que es mucho más complejo de lo que parece fabricar una hélice, y mucho más para que rinda.  No obstante, Tomas nos explicó la base, no solo demostrando que sabe perfectamente lo que está haciendo, sino tambien haciendonos pedirle que se repita ya que no podíamos seguirlo todo!Un ejemplo sería que todo el mundo sabe que cuanto más paso, si podemos mover la hélice a la misma velocidad, tendrá más empuje que si le damos menos paso.  Pero curiosamente hay límites, entre ellos el tener que tener en cuenta la velocidad del modelo, ya que una hélice con muy poco paso en un modelo veloz sería muy peligroso ya que la fuerza de impacto del aire sobre la superficie plana de la hélice podría incluso romper la hélice!  Es por ello, que como ya sabemos, los modelos lentos llevan las hélices con muy poco paso, mientras que los modelos rápidos siempre llevan mucho más paso.Mejzlik además de hacer varias dimensiones y pasos, tambien tienen variantes, como son losEvo, L, S y N.  Cada uno tiene un diseño o construccion distinto.  Por ejemplo, un EVO tiene un borde de ataque distinto, mucho más recto, el cual ayuda a reducir ruido pero sin sacrificar en diámetro y potencia.La L lleva menos capas de carbono (las que forman la parte exterior de la hélice), sin embargo debido a una estructura interna permite una mayor rigidez aún con un peso final inferior que las versiones habituales.  Esto hace que un motor puede revolucionar a la misma velocidad, pero accelerando más rápidamente.Le preguntamos a Tomas si se podría hacer una hélice cuya parte central no sea tan ancha, para evitar perder flujo y potencia en esta zona central que suele ir tapada por el carenado.  Curiosamente ya han hecho pruebas para comprobar justamente esto, pero descubrieron que las primeras 2/3 partes de cada pala no hace prácticamente nada, y es solamente la punta la que genera el flujo.Tras la reciente firbre por los aviones redonditos, como los Sukhoi o Yak, los pilotos han descubierto un problema con los carenados tan grandes los cuales tapan prácticamente toda la hélice.  Afortunadamente, debido a lo que hemos dicho antes, de que solo la punta genera el flujo, es por ello que el avanzar el motor unos centímetros de forma que el cono esté más adelantado que el carenado, esto soluciona prácticamente toda la pérdida de potencia, ya que permite que algo más de la punta pueda hacer efecto, y de esta manera, de la punta que genera el flujo, la aprovechamos toda, quedando tapado solamente la parte central que no genera apenas flujo.Tomas además nos explicaba como las hélices de una sola pala son las más eficaces. Esto es debido a que como hay una sola pala, en el tiempo que tarda en dar una vuelta completa, vuelve a haber “aire limpio” por lo que rinde al máximo (al contrario que las bipalas, tripalas, cuatripalas… que siempre pasan justo detrás de otra pala, por lo que funcionan con una proporcion de “aire limpio” y otra de “vacio” formado por la pala anterior).  La desventaja que tienen es que no se pueden usar en modelos acrobáticos de gran escala debido a que el tamaño del peso necesario para compensar la pala hacen que no sea viable. Nos mostró una fórmula muy sencilla para calcular que tamaño de tripala usar, si estamos sustituyendo la bipala que llevabamos anteriormente.  PAra hacerlo, simplemente debemos multiplicar el diametro por 0,9 e incrementar el paso en 1″ o 2″.  Por ejemplo:32*10 Bipala32 x 0,9 = 28,8.  Por tanto una 29″ de diametroResultado en tripala:29*11 o 29*12 Además de sus hélices, Mejzlik además hace otros componentes en carbono con el mismo perfecto acabado, como son sus conos.  Tomas nos explicaba que han desarrollado un nuevo método de fabricar estos conos, que hace que sean igual de fuertes, pero más ligero, y con el mismo acabado interior que exterior.  No solo esto, sino además usan nuevos platos de cono en aluminio de aviación, que además de ser más ligero de por si, es mas fuerte permitiendo un mayor aligeramiento, como podéis apreciar en las fotos. Como Mejzlik siempre está buscando mejorar sus productos, están interesados en recibir comentarios sobre sus productos, así como sugerencias, modificaciones, críticas constructivas o incluso ideas nuevas.  Por tanto, si quereis hacer algún comentario o sugerencia, porfavor mandenoslo y gustosamente se lo remitiremos. De mientras, como Mejzlik tienen tantos productos que normalmente no conocemos o se nos olvidan que los tienen, porque no pegar un vistazo a su nueva web, en:  

Conocemos a: Krill Model Meeting: Krill Model

Krill Model Factory Visit Krill-Model’s factory in the Czech Republic Taking advantage of the fact that we where in the Czech Republic for the EXFC we also visited Krill-Model, currently the leader and most recognised manufacturers for large scale acrobatic models designed for competition at the highest level. Once at the factory we met up with it”s owner, Ivo Krill, who had been so kind as to let us visit his factory, see how the models are made and take some photos to share with you all. Once we where there, everything seems so organised and prepared that it looked easy, even though we all know that this is not the case. The first thing that we see as we enter Krill’s factory is the CNC cutting machine, working permanently on all types of materials cutting everything that they will need to finish their models. Once they have the moulds clean they are sent to the painting area where they prepare the colour scheme and then paint it in the mould. Once dry they start applying layers of fibre, carbon and other materials that will form the body of the plane. At this same point they add the ribs, formers and all other supports that are required to finish the plane. Once completed it is vacuum bagged and put in an oven to dry. The following day they join the two half’s of the mould, reinforcing the joint with carbon and then removing from the mould. Now the model gets moved to the other side of the factory where they finish the model, such as the cuts for the control surfaces or gluing in the hinge system. Here we can see what the open end rudder on the big Sukhoi 29 looks like as it comes out of the mould, just needing to cut off the excess.Both the wings and elevators come out of the mould completely in one piece. They then cut out the control surfaces and throw away the piece that is not needed. It is funny seeing a wing without any control surfaces! You can find Krill’s entire range on their website at: You can even choose to have a standard scheme by changing to any colours you want!! Visitamos la fábrica de Krill-Model Visitamos la fábrica de Krill-Model. Aprovechando que estabamos en la república checa para el EXFC visitamos a Krill Model, quien en la actualidad debe ser el fabricante más reconocidos para aviones acrobáticos de competición en gran escala. Una vez en la fábrica nos encontramos con su dueño, Ivo Krill, quien muy amablemente nos había ofrecido ir para ver donde hacen los aviones, y sacar unas fotos para compartir con todos vosotros. Estando allí, lo tienen todo tan organizado y preparado que hacen parecer que el proceso de contrucción sea sencillísima aunque todos sabemos que esto no es así. Lo primero que vemos al entrar es la máquina de CNC, trabajando a todas horas en todo tipo de materiales cortando las piezas que necesitarán para completar los aviones. Una vez tengan los moldes limpios los pasan a la zona de pintura donde preparan el diseño y lo pintan en el molde. Una vez seco empiezan a meter capas de fibras, carbonos y otros materiales para darle la forma al avión. En este mismo paso meten las costillas, cuadernas, bancadas de tren… Acto seguido lo embolsan al vacío y lo meten al horno para secar. Al día siguiente juntan las dos mitades del molde, reforzando la junta con carbono y lo sacan del molde. Ahora pasa al otro lado de la fábrica donde terminan el avión, haciendo cosas como los cortes para las superficies de mando y el pegado de lo que viene a ser las visagras (tipo pasador)Aqui podemos ver como sale la dirección tipo libro del Sukhoi 29 grande del molde, a falta de cortar el sobrante.Tanto las alas como profundidades salen del model hechos una pieza. Luego recortan y deshechan la parte que no interesa. Es gracioso ver un ala sin superficies móviles! Podéis encontrar la gama entera de aviones en su web Incluso podéis pedirlos en los colores que queráis!!

Conocemos a: JetCat Meeting: JetCat Factory

JetCat Factory Visit Continuing our way home after the EXFC in the Czech Republic we arranged to visit the JetCat factory in Germany. On arrival at their factory we met with Roman Kulossek and Udo Töpfer who kindly showed us around the factory, explaining each process required to build a miniaturised turbine to the highest standards currently available, obtaining the reliability, simplicity and smooth running that characterize their turbines.First, a little bit of background. JetCat have always been a market leader in miniature turbine engines, which run on Kerosine mixed with turbine oil at speeds of over 200.000rpm in some models and amazing temperatures of approximately 750ºC. These turbines are exact replicas of the full size turbines used in aviation, which is why they have such a similar sound. Udo showed us where each different model of turbine is put together. It is amazing to see so many turbines in one place, and even though very complex and precise mechanical objects, with JetCat”s production line all looks very simple and strait forward. When the turbines are near completion, but before they are inserted into their outer case, you can appreciate the precision required, when you see the tiny size of the fuel injectors and other similar components. Once completed, each and every turbine, be it new or repaired, are installed into JetCat”s special mounting rig set up with all different types of sensors and measuring devices. It is then started three times, and only then, once it has passed all JetCat”s tests and requirements is it packeged up and sent off to the client. To assure that their turbines continue running to perfection, they ask for them to be sent back after every 25 hours of usage for a revision to make sure that everything is running perfectly. JetCat seem to be constantly improving on their already top quality products. Proof of this was their KeroStart system from a couple of years back, and much more recently their new RX model turbines which incorporate most of the electrical components inside the actual turbine, so there are much less connections required inside the model. (such as the electrovalves being inside the turbine, the fuel pump regulation being automatic..) Here we can see their new P200SX, with an update of their smallest turbine, the P20 coming soon (will become the P20SX – the SX standing for internal Kero Start). At this years Jet Power they also released their new P180RX (RX standing for Internal Kero-Start and internal valves). JetCat also make turbines for helicopters and marine models, just take a look at the comlexity of the systems on this turbine helicopter rig! Many thanks once again to JetCat for allowing us access to their factory, and also to JetCat-Spain for arranging this visit for us. JetCat Factory Visit Volviendo a casa tras el EXFC en la República Checa, organizamos para visitar la fábrica de JetCat en Alemania. Al llegar a su fábrica, conocimos a Roman Kulossek y Udo Töpfer quienes nos enseñaron la fábrica, explicando cada proceso necesario para la fabricación de turbinas miniaturizadas de una elevadísima calidad, obteniendo así la fiabilidad y simplicidad que caracterizan sus turbinas. Las turbinas de JetCat son autenticas turbinas, pero miniaturizadas, ya que su funcionamiento es el mismo,y funcionan a base de Keroseno y aceite de turbina a velocidades de más de 200.000rpm en algunos motores y con increibles temperaturas de unos 750ºC. Udo nos enseñó donde cada modelo de turbina se fabricaba. Es increible ver tantas turbinas en un solo sitio, y a pesar de la complejidad que todos sabemos que lleva una turbina, con la línea de producción de JetCat todo parece muy sencillo. Con las turbinas casi terminadas, pero antes de cerrarlas se puede apreciar la precisión que se requiere, debido a los tamaños diminutos de ciertos componentes, como son los inyectores de combustible. Una vez terminados, todas las turbinas, sean nuevas o reparadas los instalan en la bancada especial de JetCat y acompañado de todo tipo de sensores los arrancan tres veces para asegurar un correcto funcionamiento. Solo entonces se le da el visto bueno y se procede a empaquetar la turbina para su envío al cliente. Para asegurar que sus turbinas siempre funcionan a la perfección, ruegan que se mande la turbina para revisión tras cada 25 horas de uso. JetCat están constantemente buscando mejorar sus productos, muestra de esto fueron sus primeros motores de KeroStart (arranque por keroseno) y más recientemente sus nuevos modelos RX, los cuales incorporan gran parte de la electrónica necesaria dentro de la misma turbina, por tanto hay muchas menos conexiones y componentes que instalar dentro del modelo (como son las electrovalvulas, o el tener que ajustar la velocidad de la bomba de keroseno) Aqui podemos ver su nuevo P200SX. Próximamente también van a sacar la nueva versión de su turbina más pequeña, la P20 (que pasará a ser la P20SX – la SX significando que lleva el KeroArranque interno). Además, en el JetPower de este año sacaron su nuevo P180RX (el RX significando que lleva KeroArranque interno, electrovalvulas internas y cierta programación automatizada internamente. JetCat además fabrican turbinas para helicópteros y modelos maritimos, fijaros en la complejidad de los sistemas usados en los helicópteros! Muchas gracias de nuevo a JetCat por permitirnos acceso a su fábrica y también a JetCat-Spain por habernos organizado la visita.

Getting to know Secraft

Getting to know Secraft Secraft Secraft is a company who specialise in anodised aluminium components for rc modellers. Due to their ever growing product range and the top quality produced, they have quickly become one of the best known supplyers of aluminum accesories, just some examples would be their servo arms, accesories for transmitters, anodised washers and many many more.

Reparación de mi Sukhoi 29 - 3m de Krill Model Repair of my Sukhoi 29 – 3m by Krill Model

Repair of my Sukhoi 29 – 3m by Krill Model During the Italian F3M Cup this past summer I suffered a significant crash with my Krill Model 3m Sukhoi 29 The cause was clear, performing a manouver too low… Normally the model would have completed the manouver perfectly, however with the added weight of the smoke, smoke cannisters and confeti it was all just too much, with the end result being that the Sukhoi ran out of height and into the Italian ground… The result was quite disasterous, breaking the fuselage in two pieces just behind the cockpit, breaking the wingtip off and also the aileron. Dispite having already enjoyed two years of flying my Sukhoi I was not ready to move on, so I decided to dedicate some time to it and attempt a repair. Fortunately I enjoy working with fiber/composite, and even though the damage was extensive, it was also relatively clean. In one afternoon, with quite a bit of patience, some cyano and a few rulers to keep her straight, the Sukhoi was back in one piece, and even though far from flyable, at least didnt look quite so sad in the corner of my hangar. Despite most of the breaks being clean ones, there where a few areas that where unsalvageable, so I had to cut them out and replace with balsa. Once everything was back in place, and all excesively weak points had been removed, I covered everything with fiberglass cloth, both inside and out, so it would be strong enough to support the forces of acrobatic flight. Following two weeks of sanding, filling and more sanding to get her as close as possible, it was starting to look like something flyable. It was back in once piece, and where it not for the difference in colours you couldnt tell that not long ago the tail and the nose had been sitting in opposite corners of the hangar. Now it was time for the easy part, even though no less labour intensive. With lots of masking tape and preparation, it was time to add some colour to the plane. One by one, and layer by layer it started to look like it used to. After four days for the 4 colours, I once again had my Sukhoi back, as good as new, or maybe even better as I had reinforced several areas spots that needed it. After a few more days for a couple of coats of laquer it was soon time to polish and test fly. Interestingly, as I had used the Christmas holidays to finish the Sukhoi, it was actually the first flight of 2014, once again back with my great Sukhoi, and I am very pleased that it flies just as it used to, with no adverse effects for weight or any lack of power. The Sukhoi Lives Again!!

Pintando el P47 Razorback de CARF-Models Painting the Composite-ARF P47 Razorback

Painting the Composite-ARF P47 Razorback This is the fantastic P47 Razorback that I painted for my good friend Oscar Moran. It was a true experience, it was the first time that I painted a large scale model and also the first time using “special” paints (chrome). Despite all the work involved, the effort was well worth it for the end result. With a Moki 250cc 5 cylinder four stroke up front the sound is very realistic and the actual flying caracteristics of the model are surprisingly good, landing very slowly even if it does then take a while to stop rolling on the ground.

OptiPower Lipos

OptiPower Lipos With so many Lipo brands on the market, it is difficult to choose the right one for your next project. Most of these have somewhat unrealistic discharge ratings or are over-easy on “puffing” Having met with good friend Dunkan Bossion at the French eXtreme Flight Championship in 2013 and saw him show absolutely no remorse for his batteries and find them to finish his flights in the same state they started off in, I was amazed. After inquiring, and trying a number for myself, realised that these OptiPower Brand batteries actually do what they on the label! Real discharge, which results in real results, and less suffering for the actual packs themselves. With a huge range, from relatively “low” 35C Rx packs (that actually have more punch than many 60-70c packs on the market!) to their all mighty real 50C Ultra packs, with between 100-120C peak discharge and in almost any mAh capacity. Having used them in every type of model, from power supply to helicopters, EDF and even drones, can really say that they are a cut above any other pack that I have tried in the past. Just look at the pilots who entrust not only their models, but competition results, to OptiPower battery packs, and wonder why they all came to the same Opti decision! OptiPower Lipos

G-Force Aircraft: Scale Pilot (35%)

Scale Pilot (35%) – G-Force Scale pilot, 35% scale by G-Force Aircraft. Our acrobatic models are also semi scale models, and with such large canopies, in my opinion it looks terrible to have an empty “office”. G-Force Aircraft feel the same, and produce large scale pilot figures, of which the photos below do not really do justice to! The weight is amazingly light and yet they still put up to the vibrations and high G forces that we put them through. Produced entirely in Spain and for very competitive prices, try one and you will repeat again and again!
