Yes Dave I do,we have a couple of guys in the club with the frsky system,one with a JR and the other Futaba. They use the old system and they never had a problem.I converted three radios myself a Kraft gold metal series a Futaba FP N six channel and as you saw above the Proline SS . Except the Proline the other two were flown several times and the frsky performed excellent.I used the newer hack module with the three point switch and the non telemetry capable RX's. Later I replaced the frsky with the MLINK from Multiplex as I do have several RX's and I do not need to buy more from FRsky. I am very interested on the conversion of the Kraft SS series 72 and I will give it a try soon. Which SS do you want to convert?

Nick
