I'm really thinking wheel size won't matter much, especially if you flatten your ramp out at the end. My bet is once you get to a certain speed, accuracy is going to matter a whole lot more.starpug wrote:Thing is with Mousetrap you were playing with the wheel to axle ratio so you wanted small wheels on the powered axle. With Gravity Vehicle I'm thinking you may want bigger wheels because that can handle the transfer from ramp to floor better. That depends on your ramp though. Smaller wheels might however move closer to a curve though. This is something I'm probably going to want to test out.
Actually, on second thought, does wheel size affect accuracy? Assuming you place them straight, obviously.
