In my case,
The avispad keeps banking to the left.
The ailerons were both flush during the 1st crash. It banked to the left.
2nd time, i gave right trim. Even then it turned to the left.
3rd time , i gave right rudder, i set the motor to 3deg. Right and even then it turned to  the left and cartwheeled.
I dont know what was/is wrong with the plane.
P.S - all surfaces were correct, properly set and trimmed.

Did you find any solution?
Or maybe the design is faulty.

I, truly speaking, do not know.
It refers to the direction of motor in relation with the central axis of the aircraft. The motor should be tilted slightly to the right and downwards , this will counteract the left tendency. And this stands true for all pullers .

Sir,
The motor was already at 4 degree down thrust and set at 2 degree right thrust on the 2nd flight.
Even then it showed no improvement

Don't wake a Tiger until you've factored the teeth



Prabal, is the same one I maidened? If so, at that time it just needed some downthrust. It would need to be checked thoroughly to see why it banks severely left. Maybe stab is offset.

Hi Prabal, I too had this issue before. Try this "Ensure the fin is centered with the stabilizer, and that the stabilizer is level with the wings. If the horizontal stabilizer is low or high on one side, the model will screw in loops" Good luck 👍

To adjust thrust line, simple rubber bands helps many a time!
