hi i recently bougt a sportwerks chaos off craigslist. i have experience in rc but not 4wd. it is a 4wd buggy and te engine runs amazing the only problem is my left front weel wont drive. the otr 3 do. any advice will be greatly appreciated. i would really like to get it running soon

start at that wheel , take the axle apart. if its good then pull the diff out and look at it. it has to be some thing broken in the drive line

Yah the pin that holds it to spin must have fallen out
