A Jumping Mini 4WD Car Snaps an Axle After Adding 32 Rubber Bands

A maker added a linkage and rubber bands to make a Mini 4WD car jump. The first version held its legs in place with a cable tie, which had to be cut with nippers to release the jump.

A second version introduced remote-controlled release and achieved more stable jumps, but increasing the number of rubber bands to 32 dislodged a press-fit axle. Jumping while driving remains a goal for the next version.
