The trigger is the key component of the controller: when it wears out or breaks, control over the car ceases to be precise. With the Professor Motor (PMTR2018) replacement trigger, you regain the original response without having to replace the entire controller.
Restore the exact control of your Professor Motor controller with the original replacement trigger
The controller is an extension of your hand on the track, and the trigger is its most critical contact point. Over time, continuous use in club sessions or home practice takes its toll on this part. The reference PMTR2018 is the original replacement trigger from Professor Motor, specifically designed to restore the controller's functionality to factory condition.
Function and performance
The trigger acts as the mechanical drive element for the controller's potentiometer: any play, deformation, or breakage in this part directly translates to a loss of linearity in throttle response. Replacing it with the original component ensures that the response curve is exactly as Professor Motor designed for their controllers.
Compatibility
This reference corresponds to the official Professor Motor catalogue. Before placing your order, check that your Professor Motor controller model is compatible with the reference PMTR2018. If you have any doubts, consult your controller's documentation or contact us.
Assembly and preparation
Replacing the trigger is a straightforward task that does not require advanced electronics knowledge. With basic workshop tools — the appropriate screwdriver and some patience — any enthusiast can perform it in a few minutes. We recommend taking advantage of the disassembly to check the condition of the potentiometer and the internal connections of the controller.
Common errors
- Forcing the assembly without verifying the correct orientation of the trigger can damage the controller housing.
- Do not confuse trigger wear with a potentiometer issue: if the response remains erratic after the change, the cause may be something else.
- Always use original spare parts to maintain the mechanical tolerances intended by the manufacturer.
Frequently asked questions
How do I know if my Professor Motor controller is compatible with the PMTR2018?
Check the exact model of your Professor Motor controller and compare it with the reference PMTR2018 in the manufacturer's official catalogue. If you have any doubts, write to us and we will help you confirm it before placing your order.
Is it difficult to change the trigger on the controller?
No. It is a basic mechanical operation. Simply open the controller casing with the appropriate screwdriver, remove the worn trigger, and install the new one while respecting the original orientation. No electronics knowledge is required.
Is it worth repairing the controller instead of buying a new one?
In most cases, yes. Professor Motor controllers are quality equipment whose lifespan can be significantly extended with proper maintenance. Changing a worn part is always more efficient than replacing the entire unit.
Can I take advantage of the disassembly to perform other checks?
It is a good idea. With the controller open, check the condition of the potentiometer, the connections, and the cable. A complete preventive check can save you problems in the next racing session.
