Here's a C&S Electronics Falcon III single-channel transmitter that has been converted to simulated escapement control using a Phil Green encoder. I had Jay Mendoza (vintage RC guru) insert a Heathkit GD 47 RF module and the Green encoder inside this case to create a fun working and reliable "single channel" transmitter. I used it to fly a Breathless and a JR Falcon (both electric powered) on several occasions coupling this transmitter with a Traxxas 2216 or Futaba R114H receiver on 27 MHz. One blip/hold for right, two blips/hold for left and fast blips for throttle control (three position), Unfortunately, the antenna is missing now (probably mistakenly sold it with another transmitter) so it is being sold "As Is." Sorry about that but any standard coax mount antenna (27 MHz length) will make the transmitter work just fine. Thanks for looking and please see the other vintage transmitters I will be listing this week.
