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.

Mejzlik Factory visit

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 PickeringRC@hotmail.com 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: http://www.mejzlikmodellbau.com/

Krill Model Factory Visit

Krill Model Factory Visit Visitamos la fábrica de Krill-Model 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 scheem 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 halfs 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: www.krill-model.com You can even choose to have a standard scheem but changing to any colours you want!! 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 www.Krill-Model.com Incluso podéis pedirlos en los colores que queráis!!

JetCat Factory Visit

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. 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.
