RE: Suggestions for an engine I have
that is an excellent engine, a lower rpm torquey pattern engine. one of the better engines for the classic pattern era planes. the YS .60 short stroke though will give you brute power and much higher rpms. however the .61 LS would be perfect in a Bridi Escape (retracts of course) or similar 80's ballistic pattern plane. there is a vast data base on that era's plane that can be found in the classic pattern forum.
