RS Systems 6CH Single Stick Conversion
Posted: 12 Jul 2020, 23:04
When I was in college in the early 70s, I lusted after RS Systems radios. At the time RS radios had the smallest receiver, fastest servos, and used Mil-Spec components; they were the top dog. Of course I had little money then and settled for a pulse proportional rudder-only radio set which I learned to fly with.
Recently the opportunity arose to acquire a 1974 RS 6CH SS radio, and I snapped it up. I've restored it and installed all-new electronics and wiring. The original Electro-Mech RF meter had failed and there are no replacements available, so I replaced it with a digital voltmeter. 3D printing came in handy for this conversion, providing an antenna mount that let me use the original PL-259 type connection; an encoder board mount; a frequency placard to fit into the hole left over from removing the original RF board; and a voltmeter mount.
Many thanks to Phil Green who provided the programmed 7CH Encoder; it performs well. I've added two switches to the top of the TX to control the timer and the throttle cut (I fly electrics these days). At this point I don't intend to use Expo or Rates. Thanks to Martin on this forum for providing the RF Module connections identification. The RF module is a Banggood 4-in-1 multi-protocall unit.
After 46 years I finally have my RS Systems radio!
Attached are a few pix, the last four of which show the TX in its original condition. The voltmeter digits actually look much better than the photo shows.
