hi,

I have been able to complete my self made MOSS with 46" wing span.

But i have noticed a critical problem of too much nose up when ever i give throttle. The result is that every flight i am struggling to control (i am a newbie) and end up losing a prop.

So the checks i have done is
1. Elevator checking that it should be perfectly straight
2. CG is at 1/3 point on LE

What is the cause of nose up  .............. CG or Angle of attack
Do the gliders have different CG calculations compared to a normal plane.


I think the moss design has 0 degree of angle of attack.

Can you post some pics of the motor mount. have you checked the thrust angle?

Hi, try making the plane slightly nose heavy and also give a bit of downward angle to the motor.. Just a couple of degrees down and right will do..
