I soon need to order a new C box for my 582. I will be running the OEM GSC prop (came with a Kitfox III from Skystar) for the near term, then hope to head towards an IVO or similar down the road.

My engine was originally equipped with a 3.0 ratio. Is this the best ratio for a GSC, or would it make sense to move to a 2.62 ratio?

Anyone run a 3 blade GSC with a 2.62 ratio box on a 582?
