Used to seeing all the 3D jets being huge and needing at least a 200N size turbine to fly, when I saw this jet come out in Sunday flyers size, that fits in the car without the trailer, and still capable of a load of 3D vector fun, all with a 130N size turbine, I knew I had to have one.
The build was easy, taking extra care to avoid unnecessary weight, something that we already learned from the J10, and we filmed the whole process, videos can be found at the bottom of the page.
It is not a conventional style model, and it does have its own way of flying, but it is still a lot of fun, even if you need to get used to how to land as it doesn’t have flaps.

SETUP:
In my setup I use the same throws throughout the flight
I always have vector thrust on
Gyro is always on, in “flight” position, only changing to “3D” mode for hovers and harriers.

| Aileron | +- 25mm | 50% | 20% | 30% |
| Elevator | +-30mm | 50% | 30% | 40% |
| Canard | +35mm | 30% | 20% | 20% |
| Rudder | – | – | – | – |
| Vector Elevator | +-30mm | 65% | 15% | 50% |
| Vector Rudder | +-30mm | 60% | 12% | 60% |

UPDATED PHOTOS – WEIGHT REDUCTION
In order to reduce weight even further, we changed the fuel tank, the wheels, we have gotten rid of the brakes and rudder servos, and we have reduced the size of the batteries.
