Well ? My front screws were bent. New ones cleaned it right up. No more tweak. Got to hit the track for a couple of quick packs. Nice and straight.
Black/grey tires rotated just as hard as the megenta/pink but was smoother and more consistent. But the rear let go about 5mins in. Pretty much NO forward traction. Gonna throw the pink back on in the back and see what it does. I also moved the servo forward and have on power steering to spare.
Very consistent for the first 5 to 6 mins of a run.
