RE: Okay, who's the Kraft radio guru?
as far as the jr recievers any fm or even rcd will work if they have the jr shift.model numbers that i know are r-600 6 ch and the r-700 7 channel the older rx also if they say abc&w system like the ner-327x are narrow band fm rx.since i have jr transmitters i have not gotten into the airtronics.just remember that am rx should be tuned to the module or transmitter.I do the same with the fm rx and modules also but some say it is not needed but for $40 versus the total cost of a plane and equipment i call it a small price to pay.i enen do it with my current futaba units if i buy a used reciever but that is just me.
here are some of my current working kraft tx and rx and servos waiting to be installed in a j&j eyeball.also the kraft retract amplifier with one retract the other three are in the vertigo ll
