Question
Trainer Cord Compatibility

I have JR radios, a friend has a Spectrum DX6i. Is my trainer cord compatible with his Tx?

Since JR charging cords have a negative center pole, I'm wondering if the trainer cord has the same polarity. Could my Tx battery fry his Tx if we use the cord?

I haven't seen his Tx so I don't even know if the receptacle for the cord is the same.

The trainer cords are compatible. And there's no worry about polarity because no power is transferred via the trainer cord. That's why the student radio needs a fully charged battery of its own.

A little more specific. I have a JR XP9303 with a XPS module. I also have a JR Spectrum 5. Can they be used as slave and master and with what part number cord.

I go to the Horizon web site and according to them there is no such transmitter as a 9303. Also, the manual for my 9303 says to use a DSC cord without giving a part number. If I have a part number, where do I go to buy if Horizon is of no help.

HELP!!

Never heard of a "JR Spectrum 5". Do you by any chance mean a Spektrum DX5e (not JR) ?

If so then the standard Spektrum trainer cord (SPM6805) should work between a DX5e and any JR transmitter. But yours is not a combination I've tried personally.

How you set it up will depend on which TX you intend to be the master and exactly what training facilities it has.

Yes, it is labeled as a Spectrum.

You should know that Horizon is the parent company of JR and Spectrum. Actually the Spectrum is misnamed according to Horizon's naming practice. JR stood for Japanese Radio and since Spectrum is made China, it should be named CR. It's not named CR because who wants to pay big bucks for a Chinese Radio system.

Any way, I'll try the Spectrum trainer cord and see if I have a system.

Thanks

No, JR is a radio manufacturer that existed before Horizon. Back when we came along, it was being imported by Circus Hobbies of Las Vegas (owned by Bill Bennett, who also owned Circus Circus casino). Eventually Hobby Dynamics took that over, and then we bought Hobby Dy. Our Service Center still takes care of old JR customers. We worked very closely with JR for distribution in America until recently; in Europe JR was distributed by competitors such as Graupner and MacGregor. JR is now working with a new distribution company a mile or two up the road called JRAmericas.com. He also owns Advantage Hobby - you've probably seen their ads online too as they carry stuff from both us and Hobbico. It's one of the two hobby shops in town.

Spektrum is a brand name owned by Horizon Hobby. Most of our design work is done in Champaign, with the guys right outside my office door, and we have manufacturing in several countries on multiple continents, not just China.

Don't forget - it's a K. Spektrum is the proper name. And if you're German, it's spelled properly
