Alternately, you could also use a cheap ESC to do the same job. A DPDT switch would still be less expensive, even with a cheap servo to actuate the switch.

Depending on your budget, there are some wireless infrared trailer systems that have outputs to run a couple accessories on the trailers, beyond lights. These could be used to run a screw drive also.
