I can tell you how mine was set up. The output of the SCUBA tank was teed into
the line from the ground fill port. When I turned on the valve on the SCUBA
tank it was just like admitting high-pressure in air to the ground fill port.
The ground fill port goes to the pop-off regulator valve so it is pretty hard to
overfill the system. You crack the valve on the SCUBA tank and listen for the
pop-off valve to open. When it does the system is full ... unless you have let
the air in too fast. In that case the pop-off valve will release the pressure
long before the system is full. Just be carefull.
Mine was mounted just aft of the ADF eletronics bay. I have to remove the tank
to refill it. Due to the difference in pressures, i.e. 3000 psi for the SCUBA
tank and 750 psi for the aircraft pneumatic system, it isn't really feasable to
refill the SCUBA tank from the aircraft system. My 22 cu-ft SCUBA "pony" bottle
would refill the aircraft system about four times. I made it an annual
inspection item to remove, inspect, and then refill the SCUBA tank if necessary.
I only had to refill it twice in the four years I owned Betty.

The electric trim motors operate individual trim tabs on all three axis. They
are mounted in the elevator/rudder/ailerons. I know that Barry, Rich and I have
them, don't know about others.
In my current CJ I have a SCUBA Pony bottle (the small extra tank divers carry).
The tank is filled from an external high pressure air tank or compressor (I
use a SCUBA tank in my hanger; Al deVere uses a firefighter's high pressure breathing
tank) to about 1,800 PSI. It is plumbed into the main air system so
I can use it to recharge the main system tank in the unlikely event that I inadvertently
leave the air system open after landing and it all bleeds out, or for
whatever reason (flooding, forgetting to turn on the mags, too much oil from
the pre-oiler, etc.). While admitting nothing, it has been "handy" from time
to time. I do not refill it from the onboard compressor as 1) the pressure
is too low, and 2) I don't want to get water into it.
The Kevlar tanks are lighter and stronger and are available in a number of different
sizes (Paintball enthusiasts use them as storage tanks at very high pressures).
They are mounted using "U" shaped brackets. An O2 aircraft quality 40
cubic foot tank at 1,850 PSI weighs under 7 pounds and would last several years
between refills. For more information on these see Mountain High at:
http://www.mtn-high.com/index.phtml?nav_id28&product_id372
I would think that a more generic Kevlar tank would be less expensive.

BTW, I didn't discuss aluminum bottles. Mountain High has a variety and these
tend to be a quarter of the cost of a Kevlar tank. For instance, an 8.7 cubic
foot tank would weigh 4.5 pounds (22.5 pounds for a CJ at +5, 36.0 pounds for
a 52 at +8) and cost $200. Add a bit for the brackets, connectors and installation
and one has a cheap energy source for that extra start when it's just you,
the plane and a self-service gas pump at an ag field, no buildings for a hundred
miles, no phones and the only sound is the wind in your ears.

In my usual inimitable style, I am going to call into question the advisability
of an electric-only pitch trim system. The Mac servos are known for their
reliability but runaway pitch trim can be a real control problem. If it were
me, I would insist on a system that retains manual pitch trim that can override
the electric pitch trim.
Alternatively I would want to run the trim to both limits and determine whether
or not I would be comfortable making a landing with the trim hard against the
limits. If not, I would be looking for a way to have a back-up trim system.

Barry,
So why do you think they call them "Test" flights? Don't forget that
the "Experimental" passenger warning is something that the pilot should
heed too.
Good Luck!

I'll admit to being there. Good thing for tie downs so I could hand prop
it. Not that I recommend it but then I grew up with non-electrical
system puddle-jumpers.
Get *everything* right first and have the aircraft securely nailed down.
After pressure starts building up, set your brake handle, pull throttle
back to low idle, *quickly* untie the ropes and hope the FAA wasn't
watching out there from somewhere in the cornfield.

If I recall this accident correctly the problem (more correctly the start of
the problem) was with the Russian spark plugs blowing out the center of the
plug on take off. Russian plugs seem to have this shortcoming, while the
Chinese plugs do not. I am told it's because they (Russian plugs) have
been overhauled so many times where as the Chinese plugs are new (they do
not overhaul their plugs). Has anyone out there seen this failure in a
Chinese plug?

And one more. If they are seriously over tightened they are distorted and
the center core can blow out.

Strangely enough the CJ comes equipped with a perfectly good pitch trim
system in an aircraft so well balanced one hardly needs it. The roll and yaw
trim, once set, is also totally adequate. Why anyone would want to waste
time and money with a 3 axis electric trim kind of blows me away. OH!! I
forgot! It's needed for the 3 axis autopilot.
How's that for inimitable.

This will be interesting - electric trim failure that is. I suspect
that at normal speed one should easily be able to overcome a run-away
trim servo....I'm going to go full nose up and nose down trim in the
Super Pickle to simulate this with the elevator trim so I have some
peace of mind during my test flights of the project. Furthermore, I'm
going to disable the trim during aerobatic maneuvers just to be on the
safe side. The Mac type servos seem to be very reliable, but I'm
planning for the worst....
Hey, Brian, my mouth hit the floor when I heard what Randy's shop rate
is.....

Maybe it can. I think the minimum requirements for maintenance of the
Experimental category aircraft play a part in this. Just like
everything else, you get what you pay for, and doing it yourself to
save a few bucks isn't always the answer. In the "normal" GA community
the MX requirements are a little more strict...and MX is a little more
standardized.
I'm certainly not advocating stricter requirements for our airplanes,
but perhaps a more concerted effort to educate the operators in our
community....hey, wait, that's a perfect opportunity for a seg-
way....speaking of eduction, Red Star '03 will have a number of
presentations by widely know authorities on systems and operations of
our aircraft. Mark your calendar now to be a part of the largest get
together of our aircraft on the west coast...and perhaps the entire
country.

On my project I have a small air bottle that when left open will
recharge from the main air system. If it is needed, open the stand by
air to charge the system for start, when down from that flight close the
stand by air bottle and it's all ready for next time. After paying $50
for a nitrogen fill at El Paso last year, I had to come up with
something....

Barry
