New Life for JR XP8103 - Using Spektrum DM9 Module!


Hello good people!

EDIT: Providing discussion Thread over at the RADIO section under General Topics:
https://www.rcgroups.com/forums/show...-DM9-Module%21

Just a heads up for those that might have a JR XP-8103 laying around without any use and collecting dust like mine were.

About 4 years ago, I was given two (2) JR XP-8103 Transmitters from a very good friend that moved away and didn't want to move these with him. I have had these in storage for all this time and did the following:

1. Purchased some new 3-Cell, 2500mAH, 3C, Lithium Polymers for both.
2. Purchased Spektrum DM9 2.5G (Spectrum) Band module "JR" compatible.
3. Cleaned the radios and adjusted the sticks and that's it!

The Spektrum DM9 2.4G Module works like a charm, however, you need to place the radio in PPM mode and lucky me it was already when I powered it UP after 4 years in storage.

Now I have the better of both worlds, I can continue flying my older fleet that still has Super Narrow Band 72-Mhz radios and my newer fleet with the DSM-2 and DSM-X receivers. The JR XP-8103 was almost a top-of-the-line radio in it's day so, it's just amazing the quality and wide variation of switches and nubs!
