My Cub took a cartwheel, and when I started to repair, I found more damage than I want to deal with. I just ordered an Arrow 40 trainer with the idea of putting my 72 on it. I can't find any info on what 3 blade prop would be good for a 6 lb trainer with the 72, any ideas?
Forget the 3 blade prop, they are inefficient and perform poorly for that application. Get a 2 blade APC , that is about the most efficient and best performing prop you can put on that engine.
