OS Digital 3-Channel Radio Control System

The OS Digital 3-Channel Radio Control System was my first radio control system. To the right is a photo of my system, that was first installed in a homemade air boat (Cox .049 used for power). The transmitter and the receiver both had a dark blue, metal case.

The pictures below were grabbed from an auction on eBay. It looks exactly like the system I had. I had completely forgotten about the sewn leather case that went on the transmitter. It came in handy once when I left the transmitter sitting on top of my car after loading the airplane and field equipment into the car, then puling out of the driveway and seeing the transmitter bounce off the road. Yikes. The only damage was a hole in the side of the leather case where one corner of the metal case punched through.

Here is a photo of an OS 6 channel radio that went up for bids on eBay in July of 2008. I've been waiting for one of the 3 channel models.
