I have a kyosho ag wagon and would like a four stroke. I have a hanger 9 80" cub with a 50 saito engine. I really love the engine. It is so reliable. I am thinking about the saito 72 or 82. I want some real muscle. Just worried about this engine being too big for cowl. Please let me know if anyone has one of these engines or any that would be suitable. I still cant believe I found this arf nib. Someone told me that a saito 62 would be all that I need
