Has anyone used the TechnoKats Dual Motor Gear Switching Assembly. If so, how has worked? Did you go right off of their standards or did you do it another way? Has anyone had troubles with the small hed-heads on the shaft’s of the drill motors and the Fisher Price motors? If so, how do you deal with it?
I can say that it worked great for us…but i dont know how many teams have used it this year with the new motors and all, but i have one word of warning…just make sure you keep your eyes on the welds and the little hex nuts or u could possibly strip it out…your robot however will still run but it wont drive/sound quite right 
One thing I know that has worked very well for many teams is just the single motor mount designs, but those arent really helpful again this year with the new motors…
