W W! C l model.
I've always wanted to see an Akula in 1/144 scale.
How about an Alfa or Delta III/IV in the same scale as a future build.

Aha! Maybe we will produce the Alfa or Delta III/IV in the same scale in future

Lin,

I bet a Delta 4

Lin,

I bet a Delta 4 would be a very popular model.
How bout some closeups of the guts on the Akula.
How big is it?

Thanks for you suggest, but I can't understand]How bout some closeups of the guts on the Akula.[/u]

This AKULA size: Length 768mm, Beam: 80mm

Nice sub ut ifyou want

Nice sub ut ifyou want it to turn sharper make the bottom rudder one piece as I do on mine the sub will much more funner to run without to much loss in scaleness.

I like your sub, good job!

Inside RCABS

Can you provide drawings how your ballast system works. From what I can deduce from your pics your inside RCABS is like a Piston-based ballast system but instead of a rigid piston you're using an inflatable rubber diaphragm to push out the water. Is that correct?

That's a very nice demo.

That's a very nice demo.
Hmmm. Wonder if we can substitute a floating piston instead of a bladder in there? Sort of a Piston/ RCABS hybrid.
Any comments?

Aha!
Good idea!
That's easy, I can do it like your said. and I can extend the RCABS tank too. Thanks for your suggest

I've experimented with a piston

I've experimented with a piston using compressed air. It works, but something you need to bear in mind is the friction of the piston seal causes a bit of a delayed action, or in other words, the piston can carry on travelling along the bore for a little while after you stop the air pump.

This can make things a bit awkward if you're fine trimming. An alternative would be to try the same method, but use a bellows instead of a piston.
