I have a used fuel pump can it be used to make a smoke pump and how to controll it?The pump was from a Ram 500 and it is weak, but it still pumps.



Thanks Frank

Pull or cut the red lead to the Rx to disable the BEC power input, match connectors to the motor, add a battery and you're there. I usually swap over to the red JST connectors for the motor side. Check the specs, some of these GWS ESC's have proper lipo cutoff voltages so you can go with a 7.4v 2S pack.

That's the setup I use with old fuel pumps. Easy and inexpensive.

Thanks that's what I was looking for.

That's exactly what I did with my old Ram 500 pump. The nice thing about it is that you can run the pump at whatever speed you want. Initially I put it on a slider to find the right amount of smoke without emptying the smoke tank too soon. Now I have it mixed with throttle and use a mix switch to turn it off and on. It works great.
