Spektrum DX8 issues

My DX8 is from the first batch that came out. Itís been working alright except for the past three weeks. The radio needs to be bind repeatedly after one or two flights. Its been having glitch issues with my AR7100R , JR921 , AR6200 and AR61110E receivers. The last two weeks before the Orlando event I crashed my TREX700N flybarless two Sundays in a row. Itís a bummer not being able to fly at the event, but I just canít trust this radio. Iíll be sending it back to Horizon Hobby along with TREX700 broken parts.
Guys before I get comments on how Iím not using it properly. Let me tell you Iím not new to Spektrum I have been using them since they first came out. Only brownout issue with my DX7 was with the TREX500 when they first came out. This was related to static discharge from the belt not the radio,
The last crash was witness by a good friend of mine Rolando Perez (JR sponsor pilot).
I witness on two occasions at the Orlando flyin Bert Kemmerer loose signal. Once with his nitro machine and once with his electric.
Guys there is a problem!
Thanks
Luis

I swear never to try that trick again! What the hell is only money!

I always tell my friends to wait at least 6 months before buying something new, even if they were tested by pros before. 6 months in the hands of you and me (normal pilots) will say lots. I also have a friend who bought one and 2 months later went back to his DX7

Not every radio system was tested by Pros and works fine right out of the box because it was engineered and manufactured to do so.

Guys, this is a known issue, it is explained in detail by Horizon, if your DX8 belongs to the first batch, you need to send it in.

I was supposed to send mine in, but did not have time to do so before the event.

Mine was in and out of Horizon repair dept. in one day. I have a DX8 that was from the affected batch though I haven't had a problem and couldn't reproduce the issue.

You would have thought Spektrum had learned to do things right the first time by now

...especially when much/most of the engineering and software was already done by others, thus leaving little actual work to do for this new product.

Enjoy things that money can buy IF you don't lose the things money can't buy.

Why do guys have to post the same kaka at multiple sites BEFORE checking with the Vendor? Some folks just like to stir the pot.

I don't think is the customer fault for not returning a product after a recall. If your are not having problems you generally are not in tune with public issues. Specially if a product is so new no one around you is using it.

Some folks just expect their equipment that they bought with hard earned money to work and don't enjoy crashing due to someone else's neglect.

That is all good and true, but in all fairness, the important piece of information was posted.

SEND THE RADIO BACK

That does not compensate the crash losses or the agravations, but the moral as I see it, is an old one:

damn the torpedoes!

DEEP IN THE BOG

The OP is not having issues which relate to the recall. He clearly stated his issue is with the bind between tx and rx being lost after several flights. The OP also does not state that the crashes were caused by this. If you want to read between lines go ahead but I am just stating what is written. Also if you read the horizon dx8 bulletin/recall they only tell you to send it in if you are having the issue. I do find interest in the term horizon to describe the fix as an upgrade. Upgrade to what a correctly working radio.

You say you have one from the first batch. There HAVE been problems with those, well known problems by now. There have been multiple new software releases to fix many issues, some issues required a recall to fix.

Maybe start by downloading and applying the new software to make sure you have the most current load.

Then read the recall bulletin, figure out if your radio is one of the affected lot, if so, send it in.

If you're still not sure about it, send it in, let Horizon Service Center figure it out.

OR

...use your American right to free speech and talk about your questions and concerns as much as you wish in a public forum. Those that are tired of seeing the same posts can simply move on and enjoy their working radios and warm fuzzy feelings. I personally feel really put off when I have to send in equipment for a defect/recall, no matter the type of product: car, tx, engine, esc, refrigerator, cell phone...

Enjoy things that money can buy IF you don't lose the things money can't buy.

shawn,
Me, reading between the lines? If I connected the binding or glitch issue to the recall, my mistake. The OP is clearly blaming the TX for the mishaps though. Is this issue isolated or also related to software? we all would like to know!

I find interesting the OP mentioned of having glitch issues and continued using the TX. Diferent RX used in crash? Did he think the problem would just go away?
Itís been working alright except for the past three weeks.
That alone would set a few alarms off saying DONT USE THAT TX!

What I think is absolutely bad practice is to post any account without 1st going through the radio manufacturer and try solving all issues. Go online and post a mishap if there is no closure, or to make awareness of something new.

I do agree with your point of Horizon terminology or meaning of "upgrade".

I am having the same binding issue with my DX8 and AR7100R. My Trex 700 uses this receiver with the TM1000 telemetry module. It looses bind with the radio (not sure if it's after so many flights or after a period of time that passes.) My DX8 was one of the affected models in the bulletin. It was sent in to Horizon along with all my receivers. My receivers were fine and the DX8 upgraded with a cap and rectifier board.

I haven't tested it since getting my stuff back from Horizon. One thought is that my Trex with the 7100R is on memory 1 in the DX8. I can try moving it to a different memory slot. I'll post a follow up and let you know if it's fixed.

I was experiencing a similar problem with loosing link to the RX though it was with AR6100 type receivers. Changed my binding process to hold the bind button down during the entire bind process until the DX8 restarts and that seems to have solved the problem.

. . . . and the DX8 upgraded with a cap and rectifier board.
Sounds like something may be loosing power somewhere.
Any more details on that ?
