air vacuum pump for my WTC

[wroozee]

I am building the revel 1/72 VIIC u-boat. I see caswell has an air vacuum pump that is 6 volts and also has both an inlet and outlet tube connection.
My question is, does this pump need a clippard type valve to release the pressure in the bladder, or does this pump have this feature built in?

No, no pump installed dump-valve provided. So, if you're going to do the RCABS thing, you'll either need to install a solenoid or mechanical (servo driven) dump-valve.

Forget RCABS for the little type-7 -- unless you're a genius, like me, you won't be able to get enough bag in there to displace the water needed to yank that hull up to designed waterline.

Man, Andy! ... I don't know sometimes.

It's like teaching donkey's differential calculus.

It shouldn't be this hard.
