to tighten the track i drilled an xtra hole on the bottom rails buy the back idler wheel then i took a peice of plastic and mounted it to the two holes on each side of the railsand drilled a hole through that for the axle. i have a different model though so it might be different maybe try rain x or silicone on the track to keep snow buildup at mininum cause if you tighen the track to mutch it takes to mutc power to turn. mines a pos interactive toys one i keep moding it but everythings falling apart on me the track ripped the frame broke and every time i fix it somethin else these newbright ones look like the way to but i cant find any.
