Are you using brushless ??? Some motors are notchy don't feel smooth. Just the way they are

[oldenoughtoknowbetter]

yeh its a brushless. put same motor in different car with no issues at all though. even with throttle fully open it was just not moving

Screws too long and locking the armature? With the motor in and gear on does it roll? Can you spin the drive chain?

[oldenoughtoknowbetter]

screws arent too long its the same im using when swapping the motor with another buggy. when trying to turn the wheels by hand it feels stiff but when applying throttle the buggy hardly moves. theres a clicking noise when i roll the buggy with no motor in

Take motor out again see if drivetrain rotes freely as suggested by Kev B if you can move spur gear round easily and wheels spin it has to be linked to motor

Had one thought, could be something locking the rear diff, You have to watch the 2 screws at the rear that hold the undertray and rear suspension bracket dont go through the motor mount and lock the rear diff and belt.

finally sorted transmission issues. only problem is my buggy has the blade driveshafts, one is damaged and seem impossible to find new. any ideas if there are alternatives, must be something else that will fit. the thread is knackered on a rear

[Kev B]

I have some brand new rear blades on packet and the later cvd ones for a Cat ec/98. Also have some used rears I could sell

Rebuilding the diffs now. Using the co axial shafts. At the moment the diffs feel really knotchy.
Does any one know what pro thrust races fit or where to get them from? Thanks

[fidspeed]

Im sure rc bearings do them ihave had metric and imperial thrust bearings from them in past
