One thing I strongly suggest to do if you have the plastic tracks and they are tight is to add one link to each track. The real tigers had 96 links per track. Taigen stock tracks have 94 and it puts a strain on the front suspension arms. I tried 96 links and the tracks were too loose. I could max out the idler adjustments and it would still skip on the drive sprockets. 95 links per track proved to be the sweet spot. Allows you to adjust for proper tension where you get a droop in the track so it touches the top of the third roadwheel.
