Motor/Speedo flat spots
 

What are the main things that cause flat spots on motors/speedos etc
Literally a stutter at the bottom end when you hit full power from stand still etc

Is it the speedo or the motor?
Or Sensor wire???

Anyone actually know???

Sounds like cogging to me...

It's a sensor issue. Try cleaning up the sensor board in the motor (they do get mucky, especially in the motors with cooling slots). Also try swapping the sensor lead. If neither of those help, it could be a problem in the ESC - not an easy fix.

try different motor, then different sensor lead, if still there, try resetting speedo.

Thanks guys
