A fellow addict and I have built a coupla UCD3D's with identical setups for a team aerobatic routine (yes, there's a backup in storage, just like NASCAR).

New Saito 100's. Upright.

I've read several suggestions in this forum for APC 15 X 8 prop for this engine. Boy, does that ever look big. Are you really getting high enough RPM's and smooth throttle/power curves with that big of a prop? Would appreciate some tach reports.

Fer shur gonna spend a little on a Tru-turn spinner. Had to cut way too much off the kit spinner to feel safe.
