How can I modify a brushless esc to be controlled with a potentiometer?


Hi, I have some applications that could make good use of these small brushless motors in some of my projects but the problem is: how can I modify the esc to be controlled with a potentiometer? I am into the helicopter scene and have a strong background in electric motors and a fairly good background in electronics and electronic control systems. Any help would be greatly appreciated! Thanks in advance!!

Don't know if this will help but I think there is still a device on the rc market
that will allow you to plug the controller into a small circuit board and control the
ESC with the potentiometer on that board. It was marketed as a way to control
servos, for example, when setting up a plane without having to use a radio. I still
have one that I bought years ago but I've never tried it with an ESC. I think I got
it from Ace hobby but I'm not sure since there are no markings on the board.

Very easy, buy a servo tester... Some cost as little as 5-6 dollars.
