I helped when our team did this same thing last year and it worked great! very reliable and sturdy once we got it up and running. If i remember corretly there was a lot of lithium grease involved in that process. One thing that it did with the 2 motors per gearbox was it made a lot of noise from the gears grinding. due to somewhat poor design when 2 motors were used they would naturly spread apart putting pressure on the gears and not aligning them correctly. to achive 4wd we used a idler sprocket and a chain design that is very to explain. but it does use A LOT of chain so it may not be very cheap for a new team. since it is very difficult to describe the chain pattern if you are intrested email me and i will draw it up it paint to give you a better idea.
