My buddy bought a Arrma Mojave EXB. Put the factory ESC and Motor (Spektrum Firma 150). It seems to run OK but it sounds like a Sherman tank. The Hobby Shop guys (multiple) said it's metal to metal gears and it's going to be noisy but it seem excessive to me. But then again they couldn't agree on if you should grease the spur/pinion or not.
What's normal noise for that?
