Hi, I am almost in the position to order my gearbox. The gearbox is in direct link with the proppelor and rpm, so I need to make a dissision for the diameter. Now is my question wat is the max diameter I can use on the KR2-s. I do not mean the ground clearance, but I am affraid that the giroscopic force wil brake off the fire all if you use for example a 65 inch dimeter prop. Or is everybody laughting to me and say that I dont have to be affraid for that. Engine is a BMW 1200 110 hp. Thanks you all stef
