Been a while since mine has run, but it's not fond of grass. Higher than the road wheels and, as mentioned, it gets caught in the sprocket and if enough gets caught up, it will slow and even stop it. Not good on the drive train, I imagine. Fun as heck in the dirt, though.

Had problems with the suspension arms cracking at the thinnest point. Filling the breaks and cracks with the same ABS glue that was used to put it together welds 'em and they held up fine after that. In fact, the ABS glue I used has held everything else in place so far, to include the return roller mounts on the lower hull.

The track is plastic, but doesn't seem like it. Pretty tough, although I have noticed the bolt molds on the center guides are wearing off slightly.

If anything, I'd get the metal support arms, an extra set of track (stock or metal), and perhaps a fine adjust after-market idler. The stock idler doesn't give much choice in terms of track tension.

Took it out of hibernation and about croaked when I installed batteries, turned it on, and then nothing. Guess charging the batteries first, kinda helps.
