We are actually using a ratcheting strap similar to one you would use on a trailer. We are connecting the strap to the catapult and then fastening the other end to a wheel and axel which we plan on driving it with the motor gearbox combo as earlier described. I don't have experience with this kind of thing so any additional guidance would be appreciated. Thanks.
