I just picked up the Slot.it CA29A Audi, 4WD LMP car, and it’s a great car. I did remove the magnet, and had to fix one of the one-way bearings on the front wheels, which had been installed backward, but after I got that taken care, and after running the car in for a bit, it’s a great running car. It loves the technical course of my track, and should provide more consistent lapping overall on any track.
I look forward to more 4WD cars from slot it. I think this system works really well, and provides good versatility for other types of cars. I expect that other brands, especially those that already use slot.it parts, will adopt this for their 4WD cars at some point.
