10 feet is fun to mess around on. its long enough to do switch ups, spins off and on. i made it 10 feet because thats all that would fit in my yard, and its convenient to move around. i am considering building a second 10 footer.
start on a hill at the side of my house, go through a gate turn and hit it. ill post a vid of it after tonight. i have one of just hitten the rail but not of the run in.
woulda made it longer, but the pipe i used is just a random one i found in my tech class, so i made due with what i had. if i find some more piping ill make another 10 foot section.
