Didier,
the 2 12v YUASA batteries fit perfectly in the original battery box. I have had
them on both my 18Ts and never had any problem.
Weather permitting why don't you and Dominique come over on Sunday. A three ship
fly over the D-Day landing beaches in Normandy would look (and sound) nice.

Craig,
Check with Doug or Jill at M14P, Inc since the emergency air bottle on
the CJ and 52 are the same. Yes, the tests mentioned definitely apply
to the CJ. In the CJ, either one or both of the emergency air valves
could be leaking. Both are easy to get to on the CJ. So if you don't
find the leak at the bottle, check both valves. One other thing you may
want to check is the flare inside the B-nut on the emergency air bottle.
If the flare was cracked during re-installation, it will not seal up.
But a leak caused by a cracked flare should easily show up by spraying
the soapy water on the tubing going into the B nut. Leaking down in two
days is a pretty bad leak. The soapy water tests mentioned should
identify it.....hopefully.

You posted this:
"If your emergency system is leaking, the first place to look is at
the rubber O-ring under the 22 mm nut on the air bottle. A very common
problem particularly if the tank was recently removed from the airplane
and the fittings removed from the tank for inspection or servicing. The
next place to look is the emergency air valve. Remove the output line
from the emergency air valve with the valve completely closed. Spray
soapy water on the output fitting on the valve. If it bubbles, the valve
is leaking internally."
Where does one get the o-ring for the fitting on the emergency air
bottle? My system leaks all emergency air pressure out in two days.
Will do the other tests, but the bottle was removed and reinstalled once
or twice in the recent past. ALso verify this info would be for a CJ
not a Yak.

One last thing to check Craig is spray soapy water on the external air
fill port opening and see if it bubbles. If it does, you have a bad
check valve which keeps the emergency system from leaking air back out
the external air fill port. This is also not uncommon.

Got the prop balanced today at Kregg Victory's place. Well worth the travel. What
a difference, really noticeable during throttle advancement for takeoff. Great
job Kregg!
