Senton How much clearance is needed?

My Senton came with a 20T if I’m not mistaken. Which was a ? to take off.

Yeah the senton would have a higher tooth pinion because the wheels are smaller. Bigger wheels means a lower final gear ratio so the motor will need to work harder to spin the wheels. Dropping to a 15T will bring that closer to the original. Should be a bit zipper too hopefully.

And yeah the 15T in the brcc was a PITA to get off, pretty sure Arrma weld the grub screws in.
