Not sure yet if the motors will be directly linked to the small gear...
Or as in this picture, connected with a rod that will be supported by bearings.
The first version (directly connected) is more space saving and will probably be the solution.
The pipe will not be as long as in the pictures, obviously, and the bulkheads will be aligned.
Rods were added to support and give the aft strength.
Originally the thought was to give the 4 long rods the same fitting-solution as the two new ones have. (built in)
Unfortunately I forgot that and just now realized it.. Maybe I will remake the end plug in the future.
Cheers for now! Hoping to get a lot more done the upcoming week
