I had made a balsa mosel of pusher configuration with the poluhideeral wing span of 1.6m.
I had just done a flight test today and recorded some observations.
1. I did a hand launch , plane dives when throttle is more than 3/4. otherwise it climb up smoothly on less throttle .
2. its gliding is excellent , so i can say that C.G. balanced correctly on model.
3. As i increase throttle more than 3/4, i t does a nose dive. Can anyone suggest me what cud be the problem.
I checked the angle of incidence on wing and tail , Tail=0 degree and wing = 2 degree(which gives better results on the earlier made models).
The motor angle is 1degree down. Please suggest what cud be the problem
Thanks in advance.
