Vanquish VS4-10 Large Spur Gear Cover (VFD)

thingiverse

This is a large spur gear cover for the Vanquish VS4-10 Pro with the VFD tranny. It can house a much larger spur than the stock cover. I believe this can fit up to a 66T sput but I can only confirm a 64T spur will fit. The stock spur gear is a 56T. This was created with the volt up gear down mantra in mind. Due to the spur being divorced gearing down is very easy, there are no driveshafts or other parts in the way. I have a feeling 5-6S may be possible though I've settled on 4S and I've only taken advantage of half of the extra space available. Im using a 60T pinion and a 14T pinion which give a pretty normal wheelspeed good for crawling and some more demanding terrain but if you want you can get very low. Kimbrough and RC4WD makes some larger spur gears that fit the VS4-10, just look for the 3 bolt Axial bolt pattern (AX10, Wraith etc.) One item that may need modification is the motor plate, the slotted holes potentially need extending depending on the spur and pinion size. I do this the wrong way by running a drill bit and pulling it into the material (dont try this at home). To use a 64T spur and 9T pinion I had to extend each slot by 1.5mm or so. This prints in 2 pieces and the first one to go on is most likely smaller than the spur. You can squeeze the back half and get it to clear your spur gear (one side at a time) or remove the spur gear and put the first half of the cover on then re-install the spur. This requires two 8mm M2 screws to fasten the 2 halves of the cover together More info in my RCCrawler Build thread http://www.rccrawler.com/forum/vanquish-products-vs4-10-origin/613485-vs-4-s-build-volt-up-gear-down.html#post5979544
