Yak 55SP from Donuts-models, was designed by Sebastien Guillaume, an experienced French indoor pilot . I used it for  the French Championship 2008 and WAG selection at Moons and Turino.

All pictures were from my new plane for season 2008/09 with some modifications from the kit. I increased rudder, elevator and aileron surfaces!

Like my pattern plane I use cable commands for rudder and elevator.

Aileron servo is a Hitec HS56B, maybe a monster servo for indoor plane, but with it I am sure to have enough torque for aileron! Rudder and Elevator servos are JR S185 feed with 7.4v. I use this set up for the first time so I hope they will last long.

For engine and speed controler I use great values. Axi2203-46 with Phoenix 10A from castle creation. With extreme power batteries 450mah 2s. And GWS props 8*4.3.

Reinforcement wing and reinforcement fuselage by carbon rod 1.2mm on each side.

I wrote an article for Rc-Pilot after the french Championship:
