My ofna ultra lx1e

Thanks :)

Got some racing tires for it..well kind of (Supra sales caliber knock offs), and some diff tuning, and MAN, is it dialed. For the first time I could drive it easily around the track. Was easily keeping up with a bud's rc8be on same number of cells. Was really surprised..Just one thing, is it just me, or is their a problem in the motor mount? As after a couple hours ar the track, everytime i go to the track, the motor moves and i have to readjust it (I make sure the two scews holding the motor are tight).
