Here's a vintage Kraft single stick transmitter that I used to fly some vintage planes, like the Top Dawg, Upstart, and Goldberg Skylark. The transmitter was modified by Pete Waters by installing a Futaba narrow band module on 72.590 {Channel 50). It operated fine the last time I flew with it, which was about 10 years ago. Current serviceability is unknown. Thanks for looking and please see the other vintage transmitters and old radio control items I will be listing this week.
