more problems with my spektrum

[chris edwards 3]

hi all

have been flying today, untill after about 1 hour i went to turn the plane on and fire her up, but i had no responce from the surfaces at all, after taking the wing off and looking at the reciver (AR6210), and there were no llights on it even thogh the battery fill had plenty of power.

After much head scrating we manedged to re bind the reciver to the transmitter and every thing was fine after this.

i would like to know how this would have happened and how i can avoid it happening again.

[Paul Marsh]

My DX8 has done that a few times. Flew a model at a show, needed to fly it again 5 mins later, but it lost it's bind. Not only that model but two or three others. No problem, as the switch socket was JR, and re-bound via the charge jack. Still annoying, though...

The only reason is that I may had inadvertantly pressed the "Bind/Trainer" on the TX whilst switching on, if only a second will lose it's bind.

[Reno Racer]

Thats why i jumped ship to Futaba. Now T6J and T8J, and have none of the confidence loss I had with Spectrum DX7, particulary with AR500s.

[Paul Marsh]

...because you have to press the bind on the rx, then switch the TX on. No buttons on the tx to mess the bind. The Futaba method seems a much better way to establish a bind.

The rx that lost it's bind was a AR7000 and a couple of UM BNF models.

I've been using a DX6i for 2 years now and never experienced any loss of binding

Me too, 3yrs+ without a binding issue. As far as I am aware, any 'loss of bind' has eventually been established to have been as a result of incorrectly binding the Rx in the first place or operator error thereafter.

Have a read of this thread, Chris, and see if that helps. It's worth doing a search on 'bind' here - there are many other threads discussing issues.

It's worth mentioning that the procedure has to be explicitly followed - there are no short cuts!

Timbo has always stated that once bound a system cannot "unbind" itself unless the operator does something wrong.

With his experiance, I would not dispute this, as he knew his stuff, so I would say that either it was not bound correctly in the first place, or the bind button on the TX was pressed incorrectly.

I have flown Spekky for 5 yrs and never had a glitch or any binding problems

Are you certain that it is genuine Spektrum gear?

The problem sounds very much the same as the one a pal of mine had HERE.

[harris]

Another reason to avoid buying Spektrum!

[Garry Pollard]

Rather a broad sweeping statement without I notice any justificatoin for the remark harris.If the article is read it would be plain to see that they were talking about cloned Spekky, not the genuine article, which has been sold in their thousands over a long period, with I may add the best after sales service I have ever come across.

I repeat my previous statment that I have flown Specktrum gear for 5 yrs with no problems.

I am a big believer in the saying "If its not broken , dont fix it "

How do you know it's " the best after sales service I have ever come across" if you have had "Spektrum gear with no problems for 5 yrs" ?????

I think harris's comment is justified! If you cannot tell genuine from fake it's up to the genuine maker to do something before a serious problem arises. Hologram labels perhaps?

[Garry Pollard]

I may have been flying Specktrum for 5 yrs kc, but I have been flying R/C for over 40 yrs, so feel I have my fair share of different makes, and Specktum have come out on top of the poll for best aftersales service many times on this forum

I feel the way to go if you want genuine gear, go to a genuine LMS, or some outlet you know you can trust.

There is always a way.

You can also lose bind if you inadvertantly switch off the tranny before the model.

[Pete B]

Come on,gents, you two know better than to feed the trolls..........

Back on topic, have you made any progress, Chris?

Pete

[Garry Pollard]

Thats a new one on me Alan, and has never happened to me, and I do often turn off the TX before the RX

I do believe the manual states that it doesnt matter which one is turned off first. but must admit it is a long time since I read it, so dont take that as gospel

Garry

[crispin church]

even in uk spektrum / horizon i found to be very good i sent problem AR500 back and had new AR600 in replacement

have had no probs with AR6200 or AR6110 and orange rx

using DX6I

No experience of that either, Alan. If you read the thread I linked to earlier, it is clear that binding can only be made/changed/lost when the signal and - pins are connected.

The convention amongst most of us for safe operation is always Tx on first, off last, even though Spekky say it can be done either way.

thanks for the help on this matter, but at the club i fly at it was not just my radio that was having problems a few other people were having problems with there remote( some so bad the plane was lost) and some one said that there might have been some interference in the area some where.

also after talking to othere club member they said that it has also happend to them before.

[crispin church]

do you have any army personal using radio near the long range stuff can cause interference to anything

[chris edwards 3]

not that i know of, but id an old listening station close to the feild. also at the time there were alot of real planes flying over head.

there is also a area of our feild that is famous for interfeing with 35 meg

i had been using the plane and remote for ding some training and had the trainer switch, pressed up for most of the flight, but as so as i let go i had control no problem.

From personal experience I would say that interference on 2.4gHz would be highly unlikely.

We fly off an active Royal Marines base (RMB Chivenor in North Devon). Apart from the Army activity, we have the SAR helicopters based there as well. We also have regular RAF visits from all and sundry - Typhoons, Hercules, Hawks etc. etc. There is also radar and ILS constantly in operation. In other words,we operate in an extremely hostile RF environment - probably as busy as they come.

The only times we have lost RC aircraft on site have been put down to either brown outs caused by low Rx battery voltage or through other, mechanical, failures.

I must add, however, that the planes lost through brown outs have all been on Spektrum.

This is probably a factor of Spektrum being the most popular system for people taking up the hobby, or who are replacing old 35mHz stuff , not being familiar with it.

[Olly P]

I would also like to add than most, if not all 'long range stuff' is either HF, or direct sat comm, niether of which will touch 2.4Ghz.

[crispin church]

on our site we had army radio truck with a sat dish on and when any one flew in line with the way the dish was pointing the signal was lost we was within 60 meters

and when none of us flew that side of the airfield there was no probs

[YakMad]

I had the same problem with some Spectrum receivers losing bind but only in certain models and one model in particular did it on a regular basis. This had me puzzled and very worried until I realised these models all had heavy duty switches with 3 wire cables. The loss of bind was being caused by a short across the signal and ground wires which put the receivers into bind mode. My solution is to ensure that the signal wire is removed from male plug going to the battery connection on the receiver so that there is no chance of a short putting the receiver into bind mode, I have not had any problems since.
