These units have not been tested, but I know from experience working and talking with frc118 that they have had module damage due to side loads. Some other designs have addressed this by using much larger cross-sections or creating the wheel saddle from billet....I'm not sure how I'll proceed with this design.

There is no chain tensioning feature designed in. A certain amount of sprocket wear is expected. There is plenty of sprocket wrap to deal with it in my opinion.

Robonauts used #25 chain this season for the final drive without a tensioner.

There is no price on these units. Initial estimates make these far to expensive to manufacture. Miter gears are quite expensive, as are the large turned components.
