We learned a few good things too. First off the motors we used were meh for this class. Can push a beetle but not a mantis without teaming up. Perhaps we could overvolt them a tad... but I'm afraid they would blow up. Secondly we really need to glue the tires on, ha! I was super happy with our chassis, which we printed out of PLA (!) and was able to survive (mostly) a direct hit on the base from Plan F (!!!). Cuttingboard/UHMW wedges worked out awesomely. Scorpion Mini ESCs are pretty great too. Overall we are super happy with the results! We ordered the parts a couple weeks ago, designed the first rev of the chassis on Wednesday, bolted it together Thursday and redesigned it for rev 2 which we printed and assembled on Friday. If anyone is wondering, I used 1mm nozzles, 0.5mm layers, 2 layer top/bottom/perimeters, and 15% fast-honeycomb infill. Print time was about 7 hours on a gMax 1.5xt+ printer.

If there is interest I can post the STL files for the chassis & motor mounts. Could be made even cheaper if you use a cheaper esc (found some on ebay but didn't know if they had BECs?) or cheaper hubs or cutting boards (these were from Sweden! ha, I liked the color...).
