Hi, Why not use a slightly smaller nose wheel like a 1/4 inch smaller.Also the wheels that come with ARF's are to small for use on grass.On .40 size planes I use 3 1/4 main and 3 inch nose gear wheel. The reason for the smaller nose wheel is you get a good chance of touching your mains first when landing.A stronger nose gear is nice to. You might want to glue triangle wood on the back side of the firewall with some epoxy.Bear in mind tail draggers are harder to take off as you have to use the rudder.Hope this helps. Dan
