I have an IAD Extra 300L
91" wing span
it weighs 19lbs
1 x 5.9 kg torque JR Nes 591 servos per aeileron
1 x 5.9 kg torque JR Nes 591 servos per elevator
1 x 5.9 kg torque JR Nes 591 servos rudder
dual Rx
dual redundant batteries 6.0V/ 1800mAh Ni-mH
electronic kill switch
powered by a ZDZ 60RV
turing a 24X8 Menz S wooden proppeller
CG is a little nose heavy
Flight trim elevator 4 klick up from centre of foil

I have been trying to prop hang the Extra and find myself having to struggle a lot with control sticks and every time I try she will falls off to the left
Can anybody help?

All other manovers she will perform quite well on a given speed.
She will knife edge for ever at half throttle and full rudder with a touch of up elevator.

you say that it is a little nose heavy. try finding the true C/G that will help also make sure everything is evenly spaced around inside the fuz
