If you look at the current RC car's tires, it's more than a flat tire. I think you can run as much as you can even if you inject air into the tires, so that point needs to be improved
Replace the straight gears in the powertrain with double helical cut gears and it would probably be dead silent. It does seem to detract from the scale realism by sounding like a NewBright remote controlled car.
That's....not the point at all lol As much as I like the UDR, it's like saying a stock VW Beetle would win against the UDR in the Baja 1000 and then literally crush it into tiny bits without even noticing afterward. The point of this kit isn't to be the fastest offroad RC kit ever, it's to look as close as possible to the real thing and have performance/handling commensurate with its size. You could absolutely shoehorn an 8S lipo setup and get some ridiculous performance out of it, but then you lose the scale appeal that you paid so much money for.
