Has anyone been messing around with the Buwizz motors?
Hi, I did this, with the 42077 rally car.
Picked up second hand for about £30.
It’s been pretty interesting as a project honestly, I managed to cram two L-motors under the lego V6 in the back, and a servo under the dash. The stock kit suspension is pretty hard, so, I experimented with adjusting the geometry a bit to get that rally-car nose to the sky when accelerating feel. It’s entertainingly rubbish handling. Even with the BuWizz in the front it understeers a bit, but has lots of torque. Key is making sure the driveline to the diff is all fairly captive, so that you don’t lose any gears under torque.
Donuts aren’t a problem on our kitchen floor:

If you use the Brick Controller 2 app, you can control the BuWizz with a Bluetooth game controller, rather than touchscreen, which is a lot more satisfying. I’m using an 8BitDo SF30 Pro.
I’m keen to have a go at building something like the tracked racers using some bits I’ve got laying around.
