I'd placed a DA-50-R on my SIG Extra 300 XS. Maiden flight is next week. Just made a new landing gear (3" taller) to acommodate the 22" prop. With End Points / Sub Trim I'll handle the max output in order not to loose the plane.

Before, the plane had a OS 1.60 FX with 1 Lb. of lead weights in front. Now, with the 50cc, I have the same weight as before.
