Re: speed controller for fisher price

Victors will work just fine with typical R/C gear. Signal drivers are not neccesary. You will have to calibrate them, naturally, but after that they work just peachy. Forward and reverse will work just fine, although reverse will be over a very small area of travel on the trigger. Aircraft receivers are another story- some channels use a normal PWM signal and others don't. I have not been able to figure out a real guideline for them, as I've only played with 2 or 3. For a normal 2 or 3 channel radio you won't have any problem.

You will need to use more then one 7.2 volt battery pack though. 7 volts is not enough to run the victor (the voltage drop as the motor starts turning will shutdown the victor). I suggest you use two in series. The Victor will be no worse for the added voltage and the motor will run faster. I also remove the fan on the Victor.

Go forth, and enjoy the world of overvolted drill motors.
