I believe Tamiya has a basic/entry level ESC for upgrade trucks like wild dagger, twin detonator. This ESC cannot handle modified motor, be sure that you run either silver can 540, sport-tuned 540 - black can, or 27 stock racing motor.

Here is the link to this speed control:

Hope this is helpful.
