This is good to know. I've managed to gather several Kraft FM modules and receivers which are somewhat scarce. Can you provide some model numbers for the JR and Airtronics stuff?

any am reciever will work with the kraft am module if you look hard enough you can find a fm module and then you can use current jr or airtronics shift recievers as well as servos.there are kraft narrow band rx out there as well.I have had 3 radios serviced the past year by radio south since aquiring them used and while the cost is more than a new radio I prefer the kraft 7z tx and the mark lll 7cs never had any interference problems with kraft since i started flying in 1971,only crashes i had were either pilot error or batteriers going dead in the flight pack and once in the tx,this was before cycklers were available.
