you could get a really really cheap laptop,and a circuit board like the robtwar guys use,just interfaces with the usb to control the servo board,which in turn controls the servos...your going to need a 1/4 scale servo to be able to crack the throttle open,and overcome the return spring pressure.
OR...just buy a 4 channel radio,or a higherend 2 channel /RC radio,and use that with a recevier to control your throttle,you can just set the throttle with the servo adjustments on the controller...and do whatever you gotta do outside the truck. this would be a cheaper setup,depending on if you have a cheaplaptop yo ucould use.
