i got like 4-5 feet of air and it went about 8-10 feet from the jump, i think the angle was too high.. and i did roll at max speed into a fence and tree.. hehe but its a trooper... i just got a 125cc fuel tank for the traxxas and just 4 new holes and some cutting... its in yahoo... but i need to angle the muffler or get a smaller one if possable.. let me know what you guys think.. and i put some traxxas wheels on it #3673 and some badass moab 2.2 on it... it handles much better.... i want to try bigger rims and tires and thoughts?? .... and sorry im a horrable speller...
