Dual Motor Pull Back Truck with Rear Long-Travel Suspension

[DamonMM2000]

I built this Lego Technic Pull Back Truck with rear long-travel suspension about a year ago and just got around to filming it now! Two pullback motors drive the rear wheels and off-road tires! In this video, I simply go all action with the editing and test this Lego Pullback Truck in the elements! Please let me know what you think about the editing =)

Nice!

does the suspension ratchet up the motors to work? Or they are still pull back? (Never used a pull back motor)

I have to get some of these motors, this looks fun. Puff of smoke was a nice touch or else I'm going senile.

Thank you, MangaNOID! I'm not quite sure what you mean, but the pull back motors are of the same unit as the rear axle. The rear axle is hinged to the body of the truck, and a single large shock absorber links the rear axle and body (live axle suspension?) The suspension travel is extremely large, anyhow. So I simply spin the rear wheels backwards until I meet resistance before its internal clutch snaps, then I let go and it drives 

Also, I converted the single axles into the circular pieces that could attach to the large wheels securely (I'm forgetting my LEGO terms, lol). These motors are fun to work with! Creating these models are fairly easy, which is probably why I've had time to build quite a few of these instead of working on my Mindstorms project that has been sitting in a box for over a year
