While I'm catching up on the status of things....
The plane is fine. In the annual this spring, we dug into the hydraulic system. The hoses were original, and pretty stiff. The flap up/down control was super-stuff. It turns out I was wrong about the diagnosis of that; it was the cable, not the pump. That's fixed. The retraction speed is fixed. We don't really know what the problem is with the pump that had been in there, but I bought another one and that one worked fine. I still have the bad pump to try to figure out what was up.
The brakes still act slightly funny; it will be interesting to find out if it's better or worse when it's cold. We'd decided that the old problem with the mag checks might have been a weak plug, so we put a massive back in the bottom of #2. However, a couple of flights later, I had another bad mag check, so bought and installed a brand new fine-wire plug there, and it's been fine ever since.
I need to take it down to Knoxville tomorrow to get its IFR sign-off. After that, I can start flying it more, potentially.
