I have the Schrader valve installed on the airplane. My concern is putting
3000psi into a 700lb system. Does anyone out there know how much pressure
is at the regulator on a scuba system?

As far as I know this depends on the size of the bottle..big bottle 200 bars
(2900 psi..) or small bottle 300 bars (4300 psi)

The 1st stage (connected to the bottle) of an ordinary regulator can handle
easily 5000psi or more. I have pony tanks that are rated for 3600psi and i
t was common practice for us to often over pressurize our low pressure stee
l tanks to over 4000psi. Normal rental tanks are aluminum 80 cu-ft and 3000
psi. The 1st stage basically drops the amount of air going to the 2nd stage
(part going into your mouth) to about 150psi. The bigger concern is the ta
nk. Tanks are rated in psi. Divers normally care more about volume then psi
.
If you look at a scuba tank, it will be marked with a series of codes. The
first and second marking show the regulatory agency and the material of the
tank. An example would be DOT - 3AA, meaning the cylinder was made in comp
liance with DOT regulations, and it is made of 3AA-type steel. 3A and 3AA d
esignate steel; AL aluminum. The third marking, usually also on the first l
ine, shows the service pressure in pounds per square inch. That can be as l
ow as 1,500 psi and as high as 4,500 psi. If you see a "+" sign after the h
ydrostatic test symbol on a steel tank, that means the tank can be filled u
p to 10% above its service pressure. Aluminum tanks should never be filled
above service pressure and never have a "+" stenciled on them.
Each tank's on/off valve contain a thin copper "burst disk" that's designed
to burst and release pressure if the tank is over pressurized or gets too
hot (usually by filling it too quickly).

I have a gage on my filling apparatus, but still the airplane pops
off when it's had it. No worry there.

This has never been a problem for me ... all I do is slowly open the main valve
on the scuba tank ... you can see the pressure build up on the gauge in the cockpit.
The pressure relief valve will pop off if the pressure exceeds its maximum.

Same for me
I open slowly the valve of my 6L and 200bars bottle and stop a little before 55
(50)bars
The full pressure is build by the compressor unless you want to test the release
valve of tour plane which shall be calibrated around 55 bars.
You may want to build pressure in your safety air system then don't open your main
air valve and there will be a shuttle valve directing the pressure im the
safety bottle. (hope my English is fine!!!)
Don't open too fast or you will blow your system up. But if you do it normally
there is no risk.
Just open your mouth when disconnecting the bottle house from the port as there
is a loud noise of air release and you don't want to blow tour ears also....

Here's a post of two fighter pilots dogfighting. The one on the right is in a
fixed base sim and the one on the left is in a centrifuge based sim (so he's getting
actual in-flight g's). Interesting to see the stark difference in workload.
It could be confused with Yak vs CJ though.
