Speed Controllers

For the last month, I’ve been trying to find a speed controller to control the motors on my tank.

All of the speed controllers with the format I need, are for brushed motors and I need a controller for brushless motors. The speed controller controls the motor speed, and some have a switch to control which way the motor spins. I need two of them to control the motors on both tracks. I didn’t need to use speed controllers on the Lego motors because of how slow they went, but the new motors I’m going to use go a lot faster.

I’ve tried to find a controller that will work on Amazon, Walmart, and Ebay. The brushless controllers I have found, don’t have the right voltage, amperage, or wattage and are mostly for drones and RC cars.
