[September 16, 2013]

It's been almost a month since I have last been up in the RV. This has mainly been due to being out of town for work for over a week killing 2 weekends, and once I got back, I needed to catch up on things around the house. Work was light this afternoon and the weather was outstanding. I left work early and headed off to the airport.

When I first started the RV, I noticed something strange - the tach reading was 0 RPM. I knew that the tach signal was produced by the EMAG, so I did a quick mag check. Shutting down the Slick mag caused the engine to die. Power cycling the EMAG caused no effect on the engine. Clearly the EMAG wasn't firing.

I shut everything down - engine, master and the backup battery bus. When I restarted, the tach reading was working again. I was scratching my head to what could be wrong. Looking back on what I did, I left the master switch on for a good 5-10 minutes because I checked the fuel level before I pulled the airplane out. Perhaps that caused the PMAG to not start?

I did about 15 minutes worth of aerobatics, then came back and did a bunch of takeoff and landings. Lots of fun was had!

Back in the hangar, I unpacked my newest toy - an Advanced Flight Systems Angle Of Attack meter - the Pro edition. This will work with the Dynon AOA probe, so I don't have to fiddle with installing the original AFS AOA probe kit in the wings.

This was the first concerning issue with the installation - the AOA display is much larger than I thought it would be. There is nowhere in the panel it would fit!

My buddy Steve was at the airport doing an annual on his RV-9. I knew he had the AFS AOA probe also, so I looked at his installation. Steve has a very nice, cleanly laid out panel. Probably one of the best I have ever seen.

Steve has the AOA Sport edition. It is nice and compact in how it mounts to the panel. I might have to trade mine in for the Sport edition if I can't find a suitable place to put it.

Back in my airplane, I sat inside of it trying to figure out the best place to put the AOA meter. After 5 or so minutes of scratching my head, it strikes me - I can relocate the panel lights potentiometers and mount the AOA right next to my EFIS. I will be as close as it can get to my center of vision, and right next to the airspeed readout.

Here is the location I am going to attempt to put it in. I will have to do some filling on my panel where the pot holes are at now. However, they are relatively small holes, and this location is perfect. I am excited!
