Excelleron 90 engine thrust angle
 

I am building a Sportsman Aviation Excelleron 90. The instructions don't say anything about engine thrust angle, but the engine mounting rails and the front of the fuselage are angled to the right about 3 degrees. Is this plane supposed to have 3 degrees right thrust?

I didn't measure the thrust angle but mine definitely has a few degrees of right
and down thrust. Flies good , no need to change it.

Thanks Tommy, I just wanted to be sure.

I am using a ys 110 on mine and it took about 2 degrees more right thrust than the factory allowed for. You will not be dissapointed with this aircraft, other than the covering wrinkles in the sun and the decals fall off very quickly.

I am using a ys 110 with the stock soft mount. How do you add additional right thrust to this soft mount if required?
Should I increase the standard 1/8" gap between the back of the spinner backplate and the front of the fuselage in case additional down or right thrust becomes necessary?
