I'm not a big prep guy... you have to remove the rear axle to take out the magnet (and loosen the motor) so try to get the gears as smooth as possible - note how far the rear tires are set out. On one the crown gear was mounted crooked so I had it swapped. The front wheel height and travel need adjusting. I have them setup a little different on all three and I'm not sure what's best. They are rather loud so I tend to keep them off the track to a large degree.Any tuning tips on scaleauto F1 I assume you did the standard lube and tire prep ?
The braids seem to work fine against the guide so I just widen them. The rear tires are rather hard and look fairly true so I just sanded them a bit overall including the edges. I figure they will get better by turning laps... rather have the car get faster than slower over time.
