hallo
exterior koupling
the axe gave a bit more strengt with the coupling inside the sub
the free running axe demands 2 more pieces of copper to reinforse the tail section

strange point of thinking
the tail section is a bit heavier than the original design

keep up the nice work

I like to make all

I like to make all my designs so that I can disassemble as much as I can. Plus I wanted to use stock components.
That is why I have my motor output shaft going directly out a bulkhead seal like a Subtech BHS-1.
This was easier for me and allowed me to remove everything from the jar cap if necessary.
Having the U-joint on the outside also gave me more room inside on the tech rack.
I am using the bellows type seals or (Robot arms) as I call them for the pushrod outputs.
(Danger Wil Robinson)
I mounted these on the jar cap to short aluminum tubes.
I am using a stainless steel prop shaft and two copper bearings.
Except for the inside tech rack, polishing the brass and final assembly of the tail it is close to being done.
I only have about 8 HRS and maybe $15 in parts. This is fun!!.

Kinda reminds me of the Nautilus from the movie "Captain Nemo and the Underwater City." Her stern planes were set on long trusses.

Now if I can only find a round plastic clear jar of the right size, that would be cool!!
It would look like something from a old SiFi movie. BD.

Thanks Scott. I will check

Thanks Scott. I will check that out.
This is a very basic drawing of what I am thinking.
I have included a photo of the servo tray as well.
Very simple!
I am thinking of putting the ESC on the inside of the front bulkhead and the R/X on the outside of the same bulkhead. BD.
