How is the CIM motor mounted to the transmission? It appears to just be hanging out there in space.

What’s that extra aluminum plate that the FP (I assume) motor is mounted to? That’s just another plate you’ve got to machine, when you could use the orange outside plate to mount to, if you rearranged a few things.

I, personally, like the usage of 1/8” plate.

It appears that you’re extending the 8mm output shaft from the CIM motor. If this is so, what does your adapter look like on the inside? I don’t know… I would try to avoid this, if at all possible. It just seems like it’s asking for trouble, and it seems like it’d be hard to repair if it failed at an event.

Also, if you wanted to machine the dog-shifting area on just a manual mil (if you’ve got access to one) I would suggest going to a square shaped dog, like Team #716’s transmission (among others). It seems easier for students to machine, but if you’re sending it to a shop for them to build you don’t have that problem.

I think you could get away with a thinner dog, thus reducing the size and weight of the transmission, too.

It looks good, though. You’ve got a great step on a lot of teams having gone through this designing already. Good luck on your revisions and eventual fabrication (if you go with a derivation of this design).
