[The Swaggy P]

This year really helped out with breaking us out of our losing routine of trying to deal with a stock chassis, as I got a 64", 4 road wheel, track system drawn up on CAD.
The only real issues we had with this chassis were tensioning problems.
At our first competition, week 1, the track came off several times throughout the competition, mostly when we pulled a hard turn.

But after fixing that in time for our second, week 6 competition, the chassis worked extremely well, getting a LOT of traction on the carpet, while still retaining it's turning radius.

But if I could change one thing on that drive system, it would be adding active suspension to each road wheel. Making it possible to keep the chassis from bouncing around so much on the defenses, whilst stabilizing the central boulder launcher.
