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.

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..
