DSX9 Glitching
 

Hi all. I am having some problems with my JR DSX9 Transmitter, and wondering if anyine has had any similar problems, or can offer any suggestions. It is 2years old, and I have had many trouble free (hundreds) of flights with it in all sorts of models, including around 100 flight now on my Baby Boomer.

Lately I have had some worrying problems. Whilst test flying my F15 it went into hold, fortunatly with minimal damage to the jet. I couldn't fault the Tx on the ground, passing range checks with no problems. FYI, power supply was via a powerbox, with duralite batteries, all redundant.

I was about to blame my JR921Rx fitted to the Jet , then yesterday, I was teaching a friend via a buddy lead flying an electric powered glider. Whilst on long finals it started "glitching". I say glitching, as it was turing on and off, on and off. It did this several times, before I finally regained control, and landed safely.

After landing, we bound my friends Spektrum 6ch radio to his glider, and I flew it to limits of my visability, no problems.....

So I am left with an unknown problem with my TX, and my jet flleet grounded.

I am wondering if bending the TX antenna all the time eventually causes a breakdown in that tiny little grey wire, and subsequent loss of transmitting power? The TX batteries are origional, but the batt meter has never shown anything but a well charged pack.

I really am at a loss here. Any ideas?

Thanks,

Greg

Have you checked the stick wiring? There was an issue with some early radios with the wire rubbing on the sharp, square reg on the Tx back board. Remove the back carefully and check the stick wires.

did you check to see if the lights on the receiver were blinking after the 'hold' incident?

Thanks Dave. I will have a look at the stick wiring today and report back.

KC, I forgot to look at the light on the RX light after incident. I am really kicking myself over that one. As soon as I turned it off, I remembered, but too late........

Hi Greg,

Not a glitching problem but I had a problem with a DSX 9, purchased around 18 months ago, here in Sydney. It worked fine for a couple of months, but then it stated occasionally “not connecting” when switched on. After a couple of tries switching on, it would connect, and then operate as per normal. However, one day I was working with it on the bench setting up a helicopter, and it suddenly went off line completly. This was very concerning as it would have caused a crash had I been flying. This fault was intermittent and could not be easily repeated.

The radio was immediately sent back to O’Reillys, (via the retailer) who simply replaced the complete transmitter free of charge, which I am very grateful for. Great after sales service. The replacement DSX 9 I have has operated faultlessly for over 12 months now.

I would suggest you get the radio checked out by O’Reillys.

Take the back off and look at the ariel connection. The wire is very fine indeed. Also check for any chaffing on any of the wires

I have just spoken with the Australian distributor, O’Reillys, and will be sending it back for them to have a look at. I didn't realise, but it is still in warranty. The warranty period is longer than I thought. The staff at O’Reillys were very helpful.

Thanks guys for all the input.

Cheers,

Greg

Hi Guys. Just a follow up to my TX problem. The Staff at OReillys (Model Flight SA) were terrific. They found my TX had "Reduced range" and replaced the TX. It was 2 years old, and still in warranty. Their turn around was extremly fast. I had a new TX in my hands within 10 days. :D

Subsequent flights proved to be faultless. One thing I did notice was with my Baby Boomer, was the low numbers on the fade counter. I was getting used to see 100+ fades on my old tx, now I see less than 5, normally 0!!

Cheers,

Greg

Greg,

Glad it got sorted out .That was pretty much my positive experince with JR/OReillys when I had a DSX 9 problem. With radios, it is nice to get new gear replacement, instead of a repair. Cudos to them...
