I did a whole lot of laps with my M05 this weekend. I'm still running kit tires. When I first got it out on the track, the thing just spun out. I swapped the front and rear tires, which helped, then sauced the rear tires. .. Viola, a car that pushed lightly.

Since I installed the 3 racing gear diff, the car wanders a bit on the straight. I wonder why that is. I can sorta control it... But it requires some real attention.

I really need to figure out how to do sidewall gluing properly.
