Motor produces no torque

[127298256]

So I have a Traxxas stampede 2x2. I have done a lot to it and recently put a new motor and esc on it. But the first thing I noticed is that the motor has very low torque and makes a high pitch sound when you pull the throttle past half way or accelerate fast. It won’t pop wheelies like it used to. I have checked the gear mesh and the entire drivetrain but can’t figure out what is wrong. Any suggestions?

motor? battery cells? gearing? tires?.

If it makes a high pitch sound over half throttle, I would check the 3 tranny gears or spur and pinion. If it is one, it could be your driving style or a bad bearing.

The next think is a loose slipper and or glazed over clutch pads. Remove the nut on the spur and if the 3 pads are glossy, hit them with some sand paper.


What turn or kv is the motor?

Is it so hard to write the 2 or 3 extra words telling which motor and esc you installed?

The motor is not a sidewinder 4.

to be more specific it is a castle 1406 sensored 4 pole brushless motor

Well that is your problem. The 1406 motors are all too high of a KV for a Stampede. Higher KV = less torque. You want this motor https://www.castlecreations.com/en/1-10th-scale-1/castle-1410-sensored-motor-3800kv-060-0065-00
