Russian Alfa Class

The shaft from the motor to the shaft from the prop, is dead center! using a universal joint to hook them up would be perfect. So why use a dog bone along with a universal joint? The only reason I see is ease of installation only! Why add addition sloppy connections to an already perfect in-line installation with the just universal joint?

Or taper the shaft end to 3mm.

Thanks Tom,

Another good idea!

Will need to reem out the 3mm slightly to get to 1/8"! Piece a cake!

[rwtdiver]

Yes................

OK! It will be done. Going from a 4mm shaft to a 1/8" will be interesting.

Yes................

I'm with Nick on that. And put a universal at the shaft-WTC make-up point. Give that Poor WTC motor seal-bearing a break!

David,

As you can see by the photo, there is already a universal joint from the motor to shaft just before it penetrates the end cap!



Do still think it needs another universal joint on the end of the shaft on the outside just after it leaves the end cap?

Thank you, Nick, David, and Romel!!

I knew I should have not posted that photo until I was finished!!

Rob,

Everything is looking good. Nice work. Are you going to add a support to the main shaft before the connection to the the WTC? It’s a bit long of a connection to not support it in my humble observation.

Looks like it fits perfectly Rob.

Steve,

The control linkages are falling right in-line with the WTC!



The prop shaft is straight in and looks like just a simple dog bone hook up without a universal joint at this point! I hope the bow dive plains go as well!

Next with my Alfa will be the set up on the WTC (70 mm purchased from Nautilus Drydocks) There is a considerable amount of electronic to wiring to do, but with the space the inside the WTC the wiring and addition components will not be a problem!





I will be adding an addition servo to the WTC for the forward dive plains. At this point not sure if it will be outside or inside the cylinder?!

It's all down hill from here Rob. Looking good!

Thank you, Steve!

Now it's setting up the WTC. Linning up the control surface push rods and propulsion shaft.

Romel,

No! Both the upper and lower rudders do function. (David M's photos helped me a great deal in setting up the stern section) However, I did enlarge the bottom ruder by about a 1/4" wider to give me a little better turning radius!?

Rob are you only using the lower rudder ala Kilo class?
