RE: Pick an engine 4 me!
I would go with B. O.S. FS Surpass 70 4 stroke, I'm having the same issue with my YS63, Lost the plane but I'm thinking of getting a giles for it when the taxes get here. on a 40 size plane the 50 class 4-strokes will pull it but will lack on the extra power. Tomorrow we are going to look at buying the GP GeeBee for the 120 my brother needs a plane for. thase watermelons with wings do look cool.
