I just won a Somethin' Extra kit at my club's fun-fly. I don't have a small engine except for an OS .91 Surpass II. Would this be too much engine for this plane (too heavy)? I would mount the elevator & servos in the tail, maybe add an extra wing bay to each wing and increase the control surface dimensions? Or should I sell it and get somethin' better for 3D with the OS .91 4 stroke?
