I have an evo 46 engine that I'll be putting in my sig LT40. I still have the 3-blade trainer prop(new) but will this be enough for this plane. The engine manual says I can use this size and that size but no specifics. I only have about 20 flights (with the mustang pts) with 5 of them solo. My instructor recommended this plane and I want to at least dazzle him with my desision. Plus I REALLY want to fly this year as opposed to repairing my mustang. (The new mustang does look good hanging off my ceiling.)
