Ok, no responses yet. Let me ask a specific question.

Hinges - it calls for Robart super hinge points for the flaps, but not on the other control surfaces. What hinges did you use? I was thinking about use the hinge points on all surfaces.

Is the Zenoah GT-80 twin too much engine for this airplane? I have seen several guys use the Zenoah G-445 (GT-74) twin with success, and the 80 is just a bored-out 74 to add a couple of cc's to it. I didn't want to over-do the power and have problems with torque, etc., but since this plane seems to end up near 40lbs. I thought the extra size wouldn't be an issue. After all, you can always throttle back!!!

Thanks!!
