Just a quick note for the conversion process:

1) adjustable line guide

2) Bellcrank can be anywhere, but typically 1" behind the CG is what I typically do

3) Put the rudder at nuetral, in fact I have one sport model that has no rudder at all.

4) Make the tailwheel or nosewheel adjustable so that you can get the model to taxi correctly

5) I set the stabilizer at zero degrees of incidence. Some RC kits have positive incidence in the fixed stabilizer.

6) Engine does not need down or outboard thrust

7) make a box in the right wing to adjust the wingtip weight

Good luck
