I am extremely happy with my SE - Saito 72 combination. Mine balance 4" back from the leading edge with the battery mounted under the receiver. Plenty of room to move it back more when the time comes. The Saito has PLENTY of power for the SE. You will have prop clearance problems with the stock landing gear. I solved mine by using the Du-Bro Super Strength landing gear and the kit wheels. Worked like a champ and the white gear looks good with the plane too.
