I have an OS LA 46 for it - my first time with an engine that big. Biggest so far is an OS 35 FP I had on my Fancher Twister, modded for a 12-5 prop. The Twister is now, I think, a wall queen, having had an untimely meeting with terra firma attempting an outside loop. Not much damage, but when I put it back together, I found it seems to have a fatal flaw - way more down than up, and not sure I can fix that without major surgery, at which point it makes more sense to build another.
Went out with my Smoothie this morning, conditions were perfect. Got four nice flights in, but tore out the landing gear on the last landing, so now I know what I'll be doing this afternoon. Nice clean tearout, fortunately - simple repair...
