There’s a little bit of a high-speed arms race within the RC world on YouTube lately. [Michael Rectin] is in on the motion, and he’s been exploring easy methods to 3D print a good set of tires to assist his RC automotive attain greater speeds mph.
His first efforts concerned experiments with TPU. The tires seemed okay, however had little or no traction. He later moved on to VarioShore TPU, a filament able to delivering numerous properties relying on the printing methodology. Printing for the softest, and thus grippiest, attainable tires, [Michael] whipped up some sporty wanting boots for his wheels.
His tires improved over off-road RC tires in a single main means. His design didn’t undergo important ballooning because the rotational velocity elevated. Nonetheless, the VarioShore materials lacked grip in comparison with off-the-shelf rubber RC tires designed for high-speed use. The commercially-available tires additionally supplied a smoother trip.
[Michael] additionally demonstrated some neat tips for high-speed RC driving. He used a modified flight controller to right the automotive’s steering in response to perturbations, and put in a scaling methodology that reduces steering inputs at greater velocity. That didn’t fully cease the carnage although, with some incidents seeing wheels thrown off in huge tumbling crashes.
Electrical-powered RC automobiles can go darn fast lately, however you may need to contemplate jet energy if you wish to break information. Video after the break.
