Paul,

 Good to see you at Borrego this weekend. My flight back was uneventful. I've done a bit of testing and was unable to reproduce the problem I had prior to departing Brown Field. If I wasn't clear about the problem, what happened is that I discovered that my B controller in the EC2 had completely dumped memory. When I did my preflight runup and switched to B the engine quit. Copying A to B restored the program.

 I had experienced this problem frequently last summer which led to my grounding the airplane for almost 6 months while I completely reviewed my electrical system wire by wire. I ultimately found that the B chip was not fully seated in its socket. After reseating it the problem was gone and hadnt been back for the past 6 months - until sunday. I'm hoping it was an anomaly.

 I'd be interested in your subjective opinion on the relative sound levels of the three airplanes as we departed (my guess is I'm the loudest).

 If you put any video up on You Tube could you drop me an email and let me know? I've been tempted to rejoin your forum on numerous occasions, but between other forums my in box already gets swamped daily.

Thanks Mike. I really enjoyed that flyin. We should make it an annual event.
Chuck Dunlap and Tom Parkes could fly over from Arizona.
Nice place to have a flyin.

I am working on the video as we speak. Your airplane is not noticeably
louder than Dave's. Surprisingly Al's 3 rotor is the quietest of the three.
When I get the video edited I'll put it up on youtube and let everybody know
the address so they can hear the airplanes.

I suspect some of the those aluminum panels on the bottom of the airplane
are vibrating. If it were mine I would get some 1/4 inch thick PVC foam
and bond them to the floor panels with a layer of .025 aluminum on top.
That makes a stiff sandwich panel which would not vibrate and transmit
the noise into the cockpit. You might find PVC foam in  yacht stores.
Etch the aluminum with this kit, also available in yacht stores, or the
epoxy won't stick.

BTW I would uses some clear RTV and glue those CPU's into the sockets.
It is soft enough so you can still get them out if necessary.
I am surprised Tracy did not use a positive lock on the socket
as they are available but not retro fittiable.

Here are some pictures that Robin took.
