What is the use of all the extra material below the wheels axial?

The module looks supper tall. This will give you a higher center of gravity decreasing performance.

The co-axil looks complex.

I don't see the need for the gears. Most teams that i have seen that don't use shifting go directly from the cim to the co-axie with a timing belt and the majority of reduction in the yoke. Removing the gears will give you a higher mechanical efficiency and less moving parts in the high speed parts of the transmission.

The top of the modules bearing can definitely be using a bushing saving weight and cost. I personal like the thrust bearings riding on the bearing like 1640.

The plates look complex with a lot of milling operations on places that are not holding weight. Mainly where the bearings are why is this? It would be lighter and cheaper not to have to get plates that thick and mill them down even if the beaing plate are not smooth.
Over all a great start
