Can I use a R/C controller meant for servos to control a regular motor?

I am building a R/C tank and I need a controller. I have found a few but they only control servos.
I am using a double gearbox to move and steer the tank.

Yes, you can get a servo to motor driver from various sources.

This is one

THere are esc, elect. speed controlers, that plug into a receiver.  there may be one meant for a tank.
