But thats not the point. How many aircraft do you know which are pure aircraft have four wheels two up front?
Well, every amphibious floatplane I have ever flown!
But, I completely agree, Cars are best with a wheel at each corner, and planes with a wheel at each point of a triangle. If there is any doubt about that, recall that 3 wheeled ATV's are now long banned from manufacture because of numerous poor handling accidents. Been there, done that.
