I have a few friends that fly at a field about 60 miles from me and they said that there have been 3 guys out there that are using Spektrum or JR 2.4 that have had issues with losing bind in flight.
Their story is that while flying the aircraft, it loses bind and right before it hit the ground, it rebinds itself.

I told them it is not possible because in order for it to bind certain steps have to be followed in order. First you have to have the bind plug in the battery port, then turn receiver power on. Then you have to hold the bind button on back of transmitter while turning on the power to it.

I told them that they probably just lost signal intermittently and they need to to a good range check but a few of them are in a panic. I have also been informed that if I am still going to be flying my JR 2.4 that I need to stay in close.

I had a hard time not laughing when I heard this because the ones that told me are Futaba guys.

Could be battery issues. Check to see if they have "quick connect". If not, send them in. Without it, it takes up to 3 seconds before the rx will respond after a brown out.

It would seem that someone is pulling your leg. But at least the receivers are smart enough to "rebind just before hitting the ground".

You're right, binding is not something that just comes and goes at random, it's an intentional event.

Now if they happen to be using a transmitter tray and this is a DX7, there is a good possibility that the BIND button on the TX could be accidentally pressed during flight. The button extends past the outline of the TX case and if your tray doesn't have a hole in the right place, the button can be activated.

If this happens when the TX is turned on, the TX goes into bind mode and things get hosed.

But if it gets pressed AFTER TX power has been turned on, it simply goes into reduced output power mode for range checking purposes...that would cause some serious fun at random.

As noted earlier, if they are really seeing problems, it's probably a bad power system in the airframe, one not capable of maintaining voltage under heavy load.

I have hundreds and hundreds of flights with both fixed wing and helicopters using JR and Spektrum equipment. Never a single issue of any kind!! In my opinion, its truely the best equipment money can buy!!!

Thats exactly what it sounds like to me. The receiver is re-booting due to low voltage and (if it takes that long) is likely the old firmware that takes a few seconds to find the correct pair of frequencies

I did not think of the receiver low voltage reboot. I will mention it to them.

I could see that happening to JR stuff but not Futaba.

If it lost 'Bind' it wouldnt recover. Loosing Bind is not common. I think it´ll happen if the receiver bind button is pressed in hte wrong time, but other then that = no.

If you notice loss of control, it would probably be a voltage problem(brown out), and it should have to be with the older type of firmware in the receivers. With the new quick connect you wont even notice a brown out(it recovers that qiuck).

This is a JR guy. I have 1095 flights with Futaba Fasst 2.4 without one problem, on the other hand I've seen a friend's Spektrum system not bind correctly and crashed because of it.

I don't think it's because of Spektrum system not beening good, I thinks it is because of something he did wrong, or didn't do.

I'll add only this NEVER say NEVER.

has any one noticed that if you disconect the satelite receiver on the spektrum/jr receivers that they loose signal for a few seconds? could the cause be a loose satalite receiver cable?

That's interesting - I bought a DX7 when they were first released and had that AR7000 in my Raptor. Never have had a problem but one time I was flying along when I started getting what looked and "felt" like radio hits. I assumed that something was loose mechanically, brought it in quick and shut it down. Couldn't find anything wrong so I was going to power it up and do some tests BUT the RX wouldn't link UP. Turned out that the satellite RX had a loose connection with the main RX.

So bottom line, I was able to finish flying with the satellite RX disconnected but could not re-establish link after the power down. This was with a V 1.0 (or whatever it is) first gen AR7000.

I flown Spektrum Dx7 since almost two years, tre different models, all with AR7000.
Colisng up to 2000 flights. About 1500-1700 with a trex450, 200 with a evo50 and some with my .60 plank.
Never had any glitches or lock outs or brown outs or anything, the first 1200-1300 flights was with first gen of AR7000 without the QC-feature.
It just is rock steady. Two friends also have Spektrum technologi, byt in JR Dsx9. Nop problems there either.
One friend have a Futaba 12Z or something with Fasst 2.4, hes trex got crazy and destroyed itself in a trunk of a car. We dont know the reason, if it was the Fasst system or man made misstake.

Anyhow, I´d guees the both system are about as good. Misshaps will happen regardless of what system you choose.

Are you saying that the helis were in a trunk of a car and destroyed themselves in that?

With the blades folded back and a pin flag pulled out of an AZ Reg the RX will want to drive the blades to the failsafe position. Imagine what would happen.

There is at least one knucklehead on this board that has done that one.

how come the battery pack was plugged in while it was in the trunk of the car?

I made the assumption that this was an electric heli. perhaps an RX that was accidentally turned on is what your friend had in the trunk of his car - So it destroyed electronics?

I was picturing a Trex-450 doing the chicken dance in the trunk of his car.

He was about to fly, or had just flown(dont remember). It was a trex450SE, he made it ready in da trunk before flights, and put it in da trunk after the flights. So it was ready for flight in the trunk, lipo connected. I think he had it in the hand and the engine went to full throttle. He got some soars on the hand, he released the heli in the trunk and it was on full throttle dancing around until it needed a full rebuild . I think he said the Throttle Hold was on, but dont remember 100%.
