If you are direct driving a mecanum drive or any drive for that manner, make sure you support the shaft in two places. If you don't you'll bend your shaft and destroy your drive train. The tough box series from andy mark does have two support points internally and you can get away with no external supports on the shaft for short distances. However if you use an extended shaft you'll just kill the gear box and the shaft if there is no support on the other end of the shaft. My team used mechanum last year and used the P80 gear boxes with an extended shaft. It was extremely efficient, had good mount points for the encoder, and we had no problems. Hope this helps
