RE: JR Tx compatible with a Futaba Rx?
Not sure about he 35mega hurts lol. but I used Jr reciever with my Futaba had to revers the polarity inside reciver but that is not hard to do. You just move it to make it a positive reciver instead of negative. Jr 6000 but like i said don't know about 35 mine was 72 Now it is Spektrum DX7. Man the recievers are high lol.
Edited to put polarity in had it worded even i didn't understand lol.
