.51 eng. in a .40 size plane
I am looking at a second/third plane. I'm considering a sig 4 star 40 or a tiger 2 40. I love building kits I get a kick out of it, butI am concerned about my engine choice. I have a old school super tigre .51 that i bought off of my grandpa. I do mean old school. One of the old ones that was made in Italy. He said it's a real screamer. I was just wondering though if this engine is to much for a 40 size plane? Advice and or suggestions?
