JR is coming back.

JrPropo was force fed SPEKTRUM protocol DSM/DSM2/DSMX Spektrum gave Horizon the exclusivity in USA only for 5 years initialy and Horizon being the JR USA importer made them start producing radios with it, IMHO this was the downturn of JRPropo. They lost loyal customer base that initial 5 years while their hands were tied, then it took them ??? WAY TOO LONG to come up with their version of 2.4 and Horizon went their seperate way with all out SPEKTRUM branding and manufacturing, Im still amazed how some modelers think Spektrum radios are manufactured from JrPropo of JR fame.
I never had much luck with Spektrum since the Dx7/ 7202 radios, been flying Robbe/FASST modules in my JRPROPO module based trannies ever since the 9303 came out which replaced my pair of 10X. I fly large events, the biggest is FliteFest, if the winds are down and the sun is out there are 80 models airborne as the norm. The have combat 3 times daily and limit it to the first 300 in line. 100 generally never get bound that would be your DSM2 crowd, Then another 100 generally crash on takeoff or shortly afterwards once planes are airborne. With myself and 3 grandsons we never had any issues with FASST modules in JR trannies. I now am testing the Graupner radio and still no issues in this test of all tests.
So....... is Jim Drew XPS the godfather of all things 2.4 spreadrectum??? 8-)

I was shown the , then, new JR in the Radar company (anyone remember them, a great model shop,?) when I was in Hong Kong on BA VC 10 layover. That means it must have been late 70 s. So about 40 years ago. I bought an Apex seven shortly afterwards, I still have it and it still works. In fact I have most of the subsequent transmitters, Apex computer, PCM 10, heli and fixed wing, etc, right through to my current two 12xs and 28 x with its quite superb sticks. Everything still works, although the 12 xs work with the quite brilliant Weatronic RF units. That said, my 28x has proven rock solid and faultless.
Apart from a PCM 10 which died after 30 minutes ( and was promptly replaced by MacGregor) I have never had a JR component fail and that includes hundreds of servos, with, currently 18 models all JR servo equipped. ( with a couple of Ditex and a couple of the amazing new Futaba A 700s.in my Mig 29)
Just for fun, I recently tested one of my first 505 servos with the original Apex tx and Rx. It all worked !
I was recently in two model shops in Tokyo, nothing JR left, completely cleaned out by people who appreciated the brand, and bought everything available when news of JRs problem surfaced.Similarly RC Japan has nothing left.
So, I earnestly hope JR will be back, absolutely first class equpment.

It'll only be real JR if it is made using the best quality components with JR's quality control.
That's what made it a cut above the rest.
I always thought the Dee Force green frog and Team Stupid marketing effort to be a huge turn off for the people who'd used JR for years.
If it's cheap compnents in a JR case, then it isn't going to be JR, is it...
Time will tell.

The only JR item I ever had fail was the JR2700G MG tail servos, it would sharpen the teeth on Heading Hold gyros and then lock up gear train and melt down motor. Starting in 72' I went EK logictrol, MRC, Kraft Futaba then JR in 83'. I like you always felt it was a "Feel the difference" cut above the rest it just worked with smooth gimbals. Very cool history lesson on JR beginings outside US.......

I’m a loyal JR user...never had a failure with their products. I currently fly 3 jets and 2 giant scale gassers on an XG14 with regular and XBus receivers. The link is rock solid...I can fly the gassers to the limit of my vision, which is quite good, with solid control. I’m glad I didn’t jump ship!

protocols using frequency hopping technology just like everyone else.. Some discussion here:

Or google DSM-J. Looks like marketing & money making triumphed over technical merit.

I had a few failures with the MP series servo’s...fail up during the install/setup or shortly after (new)....that was close to end of horizon/jr and horizon service refuse to replace/fix them...but JR America did.....never purchased a JR servo after that....while I used to only buy JR...

Guys, I got advise some time ago on my request for help in setting up an airplane with dual flap servos using a JR 8103 transmitter. I was instructed to use the Glider mode and given good instructions on setting it up. In flying one of the 4 airplanes that I have set up that way today, I noticed that I really need to mix in a little down elevator as the flaps go down to keep it from ballooning up. I have spent the last 4 hours trying to get that done with absolutely no luck.
I am not really experienced with mixing, although I have done some of it in the regular Airplane Mode. But I am really lost while in the Glider Mode. Is anyone out there familiar with this set up? Thanks in advance for any help given. I know that there has to be a way! Chief

Chief,
This is the wrong place to post this type of question. I was able to figure this out when I had an 8103 many years ago. Using the search function I found this old thread: Flap programming the JR 8103
Don't ask me any questions because it's been way too long. The JR8103 was really a crapy radio and had several programming irregularities. Most newer Tx's have flap programs. My advise is to get ditch the 8103.
