Brushless Motor on go slow!
 

Was using the B4 at the weekend in wet/muddy conditions, it was fine until i stopped and then the car would not move and the motor struggled to turn. My Xcelorin speedo was also flashing all the lights, indicating a problem with the sensor cable. I left it in the airing cupboard for a few days and just tried it. Now the ESC seems fine and the green light comes on when i accelerate, but on full throttle the car only just moves. I have tried a new sensor lead, recalibrating the esc and 2 different radio types, all with the same result. The motor is still pretty muddy and my next step is to strip it down and give it a clean. Just wondered if anyone else has seen this before and could offer any advice.

Cheers

i would say it would have to be the motor is the esc showing that you are at full throttle when the stick is all the way up?

Yeah think so, also plugged the esc into a laptop and throttle is not limited in any way. Have taken the end off the motor and can't see anything obvious wrong :blush:

took the rotor out which is meant to be sintered and it has what seems to be a fine coating of glue over it in places??
Is there a way i can use a voltmeter on the ESC connections to the motor to make sure the right amount of power is getting through?

Think i have sorted it, may not come as a complete surprise, but i reset the Xcelorin speedo and all is well. Thought i should update, just in case anyone else ever has the same problem

Just out of interest what motor is it in the back of your b4?

7.5, which feels perfect to me
