simyo

I know this is a old topic, but I recently bought a single buggy motor, and put it in a car frame together with a servo motor on a single 9v AA batery pack and using a v2 receiver. this setup doesn't work because the motor shuts down after some driving, to start up a bit later. l Then I wired my buggy motor to a switch, controlled by a m motor wich is connected the receiver instead the buggy motor. After some driving the batery box shut down. Is there an fix for this without buying a rc unit? because I am low on money. If needed I have spare batery boxes so I can cheat a bit.
