Mini Track Loader (CAT297, scale 1:35)

thingiverse

Time to start my first RC project. The cute mini track loader from Zedpi, is the one to remix! Also liked the bluetooth addition from Backmann, this sould be inside. Looking to real life mini track loaders, the mechanics of the main beam work a bit different. So that's why I started from scratch and try to copy the Caterpillar 279D2, scale 1:35. The pivot point of the main beam is, beside rotating, also moving a bit in horizontal direction. This allows the bucket to move almost vertical, instead of a circulair motion. Nice! So that's what has to be done first. The cylinder is replaced with rack & pinion. I also want to drive both main beams (left & right), having a more balanced system and hopefully generating a bit more lift. I still did not figure out: * The best (compact) way having both pinion's attached to one shaft. (Currently they are placed on a M2 shaft, but this will require glue to hold them in place. Not very handy, since the total design is far from finished and need to be opened again and again.) * Wheels & Track's.. If you have some suggestions, please let me know ;)
