Ah, go all the way and install quad gear as some of the early biplanes, triplanes ,etc. had but I don't think the nose wheels were steerable. Extra wheels just kept bad things from happening! Probably the reason you don't see model bipes with tri-gear is that the models copy the biggies and the natural design evolution for bipes through the 20's and 30's was the taildrager designed for rough grass fields which would have been hell on a nose wheel? Claude McCullough had a scale bipe with a nose wheel which I have a pic. of someplace in all my misfiled clutter. "Someones air car" was the name, I believe?
