Iv got a 162 ROAM machine Wide. Cant get much bigger. Might try and find a straight up powder board... not sure if the "V" tail would help or not.
I usally do stay still, and that works super well for the first few rounds when speed is not an issue. Once we get 1/8th of the run left, everyone left knows that no one can make it the entire way it comes down to who can make it the farthest. I just need a way to get an extra 2-3 feet.
Bottle rockets? lol
