ZMR250 Build – Part 3 – Motor & ESC Test

In this video I let Grace take the controls of the motor and test it mounted to the 4mm arm. The first thing I noticed was the motor stuttered at low throttle. Looking closely at the bottom of the motor mount I noticed the circlip on the motor shaft was stuck against the side of the hole cut through the arm for the motor shaft. For this test I simply centred the motor so the circlip spins freely however I think the better long term solution is to enlarge the hole.

Gracie gets a chance to check out the running lights on the PDB and quite likes them.
