Truth be told, we are making progress. We went from losing it all in just under an hour to being able to keep the pressure for about 9hours. Still far from the book value of 2.5 ATM loss per hour, but at least the Nitrogen will now outlast the fuel... lol. In reality, not taking into consideration usage, how long does a full charge last in your airplane? Thanks for the help.

There is a valve to the right of the front seat and behind the seat and your righ t arm that is connected to the canopy locking mechanism. When you lock the canopy it opens this valve so the canopy seal will inflate when you move th e lever beside your right leg. This is not the valve attached to the pressu rization lever. This valve also releases canopy seal pressure if you unlock the front canopy before you depressurize it. Taking this valve out of the system, I had a charge last over 8 days. This was with the plane static and no use but still pretty significant. If I could find a new valve, I would be golden.

But that took a lot of searching. did you look under the floor at the brake valve? they tend to leak after awhile. You will need to pull the front seat. It is under your left foot. the brake cable from the control stick connects down there. The valve you are looking for is under the one where the cable connects. 2 airlines are connected to it. 19mm, short, bent, twisted wrench and tiny hands. Pretty much leaves you out. If this is the one leaking, on a VERY quiet day you can hear it. Fire cocks leak a lot, emergency brakes leak at the handle/valve.
