I've been wondering the same thing for controlling via radio, but I've avoided buying multi-channel devices that can cause the price to sky-rocket. Do you suppose there is any way to combine a few different frequencies (maybe 27MHz, 49MHz, etc) salvaged from cheap RC toys and use RC potentiometors to remotely control with skid steering? It is definately not the most reliable way, but it would be homemade and cheat.
What do you think?
