hello.........i am putting together a mahem 40...planned to put a 90 four stroke on it.......but.....the instructions are really, and i mean really , stressing that nothing larger than a 70 four stroke be used..........anybody out there flying one now with a 90 four stroke.....thanks...........pault
The big brother, 90 sized Mayhem, also says no larger that a 120 4-stroke and there are a lot with saito 150's. I have the Saito 125 on mine and it flies the plane strong with unlimited vertical.
