Whats a Good engine for a kadet Sr arf.
MY dad has a MDS 58(garbage)but the motor is not broken in yet. So it has some potential. you have to fly it about 3/4l throttle the entire flight. I hate MDS I told him not to by one but he did anyway.
I think a OS 46 would be great. It is designed to fly slow. I know guys that built the kit that flys theirs w/ a 40fp, and that was over powered. Depending on the weight, I think the 46 will be fine.
