I believe that the attached photo of my Spacewalker (taken by the fellow modeller/photographer evan) clearly shows that there is plenty of clearance when using a 18x6 prop.

The engine is a CRRC Pro GP26R (26cc), that overpowers considerably this charm lady. Certainly a 20cc gasser would be more than enough for any aerobatic manoeuvre, except maybe 3D stuff (which would be ridiculous for this plane anyway).

Please note the apparent up-thrust needed to fly the plane straight (@5300 rpm), combined with the elevator up-trim (both shown in this photo).

Any proposed solution would be welcome...
