And here i was thinking that you couldnt overpower a plane... that being said I try to stay within the guidlines of the mfr. of the airframe, but almost every plane i build i put in extra supports and braces. no need to be caught off guard with the motor flying and the tail feathers sticking out of the dirt.

Are you saying the OS 91 is too much for the plane? The specs say.61 - 1.00 (2-stroke), .72 - 1.00 (4-stroke)
