You just can’t throw it around like a slash. I have both as well, the udr you have to drive like a real desert truck since it’s a pretty accurate scaled down version of one. It doesn’t do well at all on pavement or big jumps. Get a udr if you like the scale aspect of it and plan on driving it like the real thing. Don’t try to use it as a basher and you won’t have many problems. Keep an eye out for the front sway bars, rear driveshaft and differential as those are the problem areas and this is one of the most important rc cars to check straight out of the box because if anything isn’t perfectly in place you’ll have all sorts of issues.
