From the man I work for.

***********

I can add to XA's info. The HB engines were used by RS Systems early in their contract with the US Army for the FQM-117B Mig Target Drones. This is the RSG (receiver / servo group) manufactured by RS for those drones. How it got mixed in with the HB engines is anyone's guess. The rotary switch does indeed change the RX to four different frequencies: 25.450 MHZ, 25.534 MHZ, 38.530 MHZ and 41.030 MHZ. (I used to know these by heart but I had to look at the faceplate on my TX - XA is correct it is a bear that weighs a ton - to remember them.) These frequencies were set aside worldwide to use for drones and RPVs.

I was the Training and Field Service Manager at RS and went all over the world to supervise and fly RS's drones. Some of the assignments were beyond cool; ships in the North Atlantic, moving force exercises at the NTC, etc. Lots of good and some bad memories. After RS lost the contract Goldberg won it and hired me to run the whole thing for them as they had never had a military contract before. More memories.

Now I have been at Hobbico / Great Planes for the last fifteen years and will finish my career here. Thanks for the stroll down memory lane.
