ORIGINAL: sillyness
If you are flying upright or inverted at full throttle, then you don't have a 3D plane (not enough motor).
I don't fly it at full throttle. I didn't mean to say this. Sorry, poor English...
What I wanted to say was, at minimum speed (close to stall) or at ''normal'' speed.
It is a 3D plane and it has already 2 deg right thrust. I will mix the rudder with gas if necessary - if I increase the thrust angle the cone and the cowl will not align.
