DSMX Not Binding?

[Andy from Sandy]

I can only point you to this thread on HeliFreak written mostly by MrMel regarding Spektrum and v-bar. Some of the information looks pertinent to you guys.

Spektrum users - Which mode should I run? READ! - HeliFreak

(it is a long thread)

This looks very similar to people reporting signal errors of one kind or another with the v-bar, so it is not limited to just with the Vortex.

Like the V-Bar the Vortex can only process the signals it receives, if these DSMX sats are not locking in on a siganal then the FBL unit is just an ornament..

Andy Kirby was saying yesterday Andy that he had the same sort of things going on with V BAr and Vortex. What worried me a bit was the failsafe kicking in, was that what happened yesterday when the engine cut? I know I'm having bearing issues and this'll be sorted this week but it sort of makes sense

Perhaps change that to idle position instead of cut position before next week.

[waveydavey]

Already done and that was how I flew but because it's not idling particularly well suddenly going to idle position under load may have been enough to cut

Dave, are you getting any issues when using DSM2's?

[Mark_T]

I tried some more binding tests with the DX8 in forced DSM2 mode, once I got more than 1m away the binding became much more erratic and inconsistent.

Reverted to DSMX and binding was also erratic at that distance. I don't think this is a distance related problem any more than in general with Spektrum binding.

I can confirm my 2 satellites are from different batches if that helps at all.

Not sure I can contribute much more to this at the moment, but if anyone thinks of anything useful I'm happy to help further.

Sorry mate I flew with DSMX, but although it flew okay I am a bit worried now that the engine cutting was down to the failsafe kicking in. No real way to prove it but DSM2 for me is the way forward at the minute

[...] No real way to prove it [...]

You can do some range testing and observe the stats in the flight log menu. It tells you how many times the Vortex had to change over to the other sat and how many times failsafe kicked in. Give both sats a good chance to receiver the signal... don't put one hidden behind the heli frames during the range test.

DSMX Not Binding?

Angelos asked me on Sunday if I could send him my DSMX sats so he could run so tests with them, as the DSMX sats they were using during pre release testing had no issues.
The feed back so far sounds promising.

[waveydavey]

DSM2 no issues whatsoever on the bench, the binding is quick and the startup from the VX1 is best part immediate. I'll do some range testing tomorrow, I was getting about 20 paces away with DSMX before I was losing 1 sat, I'm expecting it to be fine

[Flat Eric]

I am just setting one up on my 700, DSMX sats bind no problem, no hesitation or flickering

Make sure you range check, in fairness we don't know whats causing it, cold, proximity. What I do know is that DSM2 clears almost instantly.

[Angelos]

I've tested all possible combinations using waveydavey's DSMX sats and my collection of Spektrum radios. I was only able to reproduce his binding issue with my DX7 and his DSMX sats. My own DSMX sats work fine. I am continuing to investigate. In the meantime I would advice that you do a range check even if all appears ok during binding.

Did you try forcing a DSMX tx into DSM2 mode?

I was able to get similar results to Dave's using my DSMX satellites with a DX8 forced to DSM2 mode.
