If you can perfect the shift on the fly and have your low gear have high torque and your high gear have good top speed, you will most likely be a force to rekon with. Reason why? Most 2 speed transmissions have pretty bad low end torque and good top speed. the problem with this is that if you get into a push match then your extra gear is pointless because you cant get away to use it. so a high torque low gear would help you get out of push matches which of this year we all know from now on will happen, and a top speed high gear will help you get away from your oppentes with ease. so the choice is up to you. personaly that is a lot of stuff that has to work in order to just get the robot moving not even to mention the rest of the robot that has to complet the game. my advice, buy a 2 speed transmission from andy mark or some other robotics company, build it and see how it works. then if you think that you can do what a professional company could do it and make it run well in 6 weeks then I say go for it. But as for me and my team will let the big first dogs do that and we will stick with our simple yet effective transimission which has so far got us to the finals two years running. Good luck with your transmission and hope it al works well in the end.
