Small RC Car drive system help?
I have been looking online all day and i haven't found anything. I am looking to turn a iPod touch case into a small rc car using a canabalized rc toy that I got from a friend. I am using it for mainly its transmitter/receiver and motor controller. All would be well and good but one gear in on of the gearboxes is shot. I have many other hobby motors and two that are the same that I want to use instead but I don't know if I can without putting a gear box on them first or if I can, like I want, attach the axle right to the motor spindle with a jery rigged shaft collar. Just for reference I DO know about building things like this I am on my schools robotics team which I founded but in vex not only are the hookups male instead of female the motors are like servos and they have built in gearboxes (they come as a module). Any ideas or advice would be greatly appreciated and if I could get help asap I would love it. Thanks in advance.
