ORIGINAL: Yosh70
It was a custom made one from a friend with a CNC machine.....full bearings, airplane landing wheels . No its not adjustable, it just bolts onto the back with a supplied plate. Very sturdy and obviously gets removed when we hit the dirt.
All together, it was around $75. Not cheap but then again, this hobby aint cheap.
ahhh
hmm maybe I should try and make something out of delrin rods I have laying around, and the current wheelie bar I have from HPI.
