We are building a Extra 300 kit from great planes and we are having a hard time deciding on what engine to use and we are thinking of using a O.S.-.55 -.61-.75 as our options and they are all powerful engines but the weight of the plane and where the weight is on the plane (tail heavy, nose heavy) decides what engine to purchase.

What is your option on what engine we should buy?
