My conventional gear plane just will not taxi well in our grass field. C.G. is good etc but noses over if not careful. One of the fellas said get some bigger wheels. I have some 4" and 3" wheels but what I discovered because I did not look is the axles from Debro I have are short for the larger wheel. I think I need the 3/16x2 size for the 4 incher not sure about the other. What is your thoughts here and how to the ajustable axles work. When I get finished with this plane, I will be a expert for sure. gphil
