How do I know if my rx is high or low band? It's a futaba fpr127df, got it without crystal.

usually there is a ch number sticker on them when they are sold with a crystal if you bought yours used from someone and they removed the sticker you are kind of out of luck.the only thing you can do is send the tx and rx to futaba or radio south for tuning to each other.

I have a low band futaba rx and need to use ch.50.I called radio south and they said put a crystal in it and go fly.

If you mean the round silver one, Its half gone. Only can see 72.790 on it. Thanks

I fly on 36, at the low end of the high band. Should I risk it???? Passed range check at 30 meters tx annt. down.

do a real range check by walking with the antenae extended all the way until the plane is as far away as you fly .leave the tx and rx on while you walk and touch no controls,a helper should observe that nothing in the plane moves on your walk out.when at the limit cycle all the controls to insure proper operation then there will be no doubt

I think 72.790 is channel 50. Thats high band.

I used this reference after a quick google: http://www.gws.com.tw/english/product/receiver/010.htm

Hi there Venom 290

If you look into the receiver where the crystal goes in, if there is a red color near the plug in it is a high band receiver. No red, it's low band.

Regards,

Dennis

My Feedback: (11)

If there's no red sticker on it that says high or low its possible that it was manufactured before high/low came into vouge, if Tony or Ben (radio south) told you not to worry about it then that would be good enough for me.
