RE: .70 4-stroke. Need a plane to put it in
Yes that would be another good plane. I didn't realize the Sundancer would be that much. It goes for $249 in the US. Any plane with simular weight and wing loading would be a good plane for that engine. Keep in mind a .70 four stroke is roughly equal to a .55 two stroke in power. Any plane rated for a 50-60 size two stroke should work fine.
