Why do you need a speed control for the motor? Couldn't you just add a contact to the trigger, so right as you start to pull it the motor turns on.(kinda like the nightfinder and it's light)
Going from zero to full destroyed the gears. It has to charge up because of the friction. This thing really was not designed for these rpms. I'll dig out the battery/motor and find out what the power values are, thanks.
