I tested kangaroo yesterday and flies OK. C.G. is 105mm from the frot edge wing tube. But Im not satisfied with elerons and elevators which are mix together and they must be 3-4mm up for horizontal flight with 1/3 power. With full power I have to trim down and when idle I have to trim up. I put 4 washer to lay at the back screws... I would like to have the control surfaces in line with wing. Probably the turbine is to much up at the rear screws... What do you mean??

Thank you!
