Just starting build on my second plane, sig 4star 40, looking for your suggestions on best engine. I fly at altitude so I have to go up a bit, my eagle 2 trainer runs an OS 46
thanks in advance
Stock requirements are a 46 2 stroke and a 56 4 stroke. I agree the 50SX for 2-stroke power will give you what you want. The Saito 72/82 for 4-stroke power would be just about right
