The first photo is a pocket reference for the B-29 line mechanic. During the last several years of dad's life he kept this on the table next to his bed and would refer to it nightly, according to my mom. His life was certainly defined by his time in the military as a flight engineer for the B-17 and B-29.

While he used the printed manual for the '29 he had no such need for the '17, by far his favorite aircraft. He new the location and specs for every rivet, nut and bolt on the '17. Couple of years before he past my siblings and I gave him a ride on the Yankee Lady. I am told that while sitting on a jumpseat, he rattled off the location and min/max readings for every gauge in the airplane from nose to tail. For that flight he started all four engines via the current flight engineer, who was grinning from ear to ear. Dad did this vocally from his jumpseat, eyes closed and ears opened. He remembered the sounds from so long ago.

I put in a couple of shots of this glorious aircraft.

Below are the PCM10's. They include the PCM10, PCM10S, PCM10SX, PCM10SXII, and the PCM10X. All of these radios offer both ppm and pcm modulation. The PCM10 is pcm-z modulation only, while the others have both pcm-s and pcm-z modulation.

Below are the XP8103A and the XP9303A. Later, JR built the X9303 which was a 2.4 Gig radio exclusively, didn't use the J72 module.

The 6 below are the earliest that I have found. I The Apollo is my latest acquisition. Yes, it has the module for rf. The user interface is very simple. There is a single mix for aileron/rudder. A switch turns it on/off and a pot controls the amount of mix. It does have servo reversing. Position of the reversing switch also controls the master for the mix.

Just received a Century 7 Single Stick. Needs to be cleaned up and then I'll post a pic.

I now can focus on the XG11MV and I believe that the collection will be complete. Keep in mind that my focus is on only those radios that were distributed in the US. There are other models out there but were all off shore as I understand it.

I decided to use JR instead of Airtronics for the RF on my single stick. This allows me to maintain compatibility with my JR equipment, including the use of synthesized modules. Further, There are a number of plugin modules that allow the use of 2.4 Gig. I did have to make a few mods to interface the encoder with the JR, but I implemented the mods in such a way that the Airtronics can be reverted back to factory at will.

The Airtronics did not have an access door for the battery. The entire rear panel needed to come off to get at the battery. I have standardized on Li-Fe batteries which require a special charger, not a wall wart. I made a door that allows me access to the battery easily. Since I had already destroyed a JR back panel to get at the module cradle, I used the leftover JR cover on the battery hole.

I do have a stock Airtronics rear panel to use if I ever decide to bring this radio back to stock.
