    Limitless Arrma limitless pinion problem

    I purchased an arrma limitless and put it together. I was wondering why the factory 27t pinion and 34t spool do not come close to meshing. Motor mount is as close as it will go towards the spool. I even purchased a 30t pinion to see if the size difference would help and it still doesn’t mesh. Am...

    Heyo guys I’m in a bit of a dilemma here. Me and my dad both run 800kv Castle 2028 motors and no matter how much red loctite we put on our set screws they will always come loose. Is there any company that makes pinions with grub screws that are bigger than 2.0mm? Thank you for your time.

    Felony Does the higher gearing make it louder?

    I switched out the 16 tooth pinion for the 23 tooth. Does the higher gearing make it louder? Also there’s hardly any coast at all. Almost as if some brake is being applied. Is this normal with higher gearing? Any help will be appreciated
