I have a SpektrumDX7 and an old JR XP6102. Can I use the JR as a buddy box? Do I have to pull out the antenna? Do I have to pull out the crystal? Do I need to turn on the JR? Also, what should I do about the settings on the JR? Will all controls be transmitted from the Spektrum DX7?

Tomorrow, I'm gonna go get a buddy cable and see if it will work. This coming Thursday is my very first flight and I'm gonna make sure I have an experienced pilot to maiden her first.

Spectrum and JR are the same. Whenever you are using a computer radio pick an empty model memory slot for training. I can't remember if the slave has to be on or not, but the battery has to be in it with a charge.....good luck in your trainning and welcome to the addiction

and just to be safe, make sure both radios have the same settings, EPA, expo, channel mixing, etc etc

The slave radio does not have to be turned on as mentioned above, with the slave set on a vacant airplane model memory. Set the master radio your DX7 in P-Link mode, plug in the slave box and you should be good to go!

Is the link cable a special cable or is it the same as the MONO audio cable?

For JR/Spektrum the cable is a simple mono audio cable that can be purchased at Radio Shack.

Not true for Spectrum and JR, is true for Futaba. On Futaba, and I think Hitec, you do not have to have a battery in the slave but in JR and Spectrum, you do.

Thanks,

I will go get the Mono Cable from Radio Shack tomorrow.

Escapade balanced, Lipo battery charged, Fuel ready, troublesome engine finally tuned - ready to maiden.
