RE: Dang man

I know you're not bashing specifically, but the post following yours is certainly bashing Spektrum by calling it junk, never buy Spektrum again, etc. etc. I also very much remember the first brown out fix. It was nearly anarchy around here for 6 months whenever the subject of Spektrum was brought up. But you have to admit that nearly every crash where Spektrum RXs are onboard is almost instantly blamed on the Spektrum equipment. No matter what, it has to be a Spektrum issue. I'll bet dollars to donuts that 99% of crashes blamed on Spektrum malfunction is either mechanical failure or pilot error (i.e...didn't adequately charge rx battery, ect.).

I agree radio malfunction is possible in this case. But I think it's likely that something else was the cause. There's several videos comparing a brown out recovery of Spektrum vs Futaba receivers and the Spektrum was quicker every time. You're right though that we don't know what rx was in use. I think most T28s came with an AR500 and I'll bet there aren't many of the older AR500s still out there without the updated software fix for brown out recovery. If I had an older AR500, I would certainly send it in to Horizon for free replacement.

I simply charge my RX batteries and TX for at least 12hours before flying and I've never once had a problem. I also put on a $1 voltwatch from Hobbyking on my bigger nitro model and I've never had a problem with greater than 5 flights at 12 minutes each.

OP stated DX5. I'm guessing he meant DX5e, which is a full range TX.

Let the Spektrum bashing begin....

FWIW, I've never had a single problem with my DX6i, Ar500, Ar6200, and Ar6110e. Nothing, nada, zippo but flawless performance. I've used 4.8V, 6V, and lipo batteries with no issues whatsoever. I also used it with a BNF Blade Heli with zero issues and that is using a 1S 3.7v lipo.

Not bashing, the person has a problem, is looking for answers, I gave them a possible scenario.

And you can't say Spektrum hasn't had their problems with voltage issues. Apparently you don't remember the first brown out fix, add a capacitor to the rx to help with voltage sag. It's still available. Or how bout a personal one, one where the tx after making a setting change would hunt back and forth between the old and new settings unless you rebound the rx, and sometimes even that didn't fix it. Many a retract servo went to an early grave over that one.

And remember he has the most basic one in the line other then the RTF tx's. They have their limits too that aren't as good as the 6i. Range is much different, the 5 is a park flyer set up only, heck if he got it out far enough it could have lost the signal. Or weak batteries in the transmitter which reduces the range. Or even a weak pack in the plane which does you know what when the voltage sags below the rx's threshold.

Not bashing just giving them possible things that could have caused a problem with the items they listed that were being used.

If they had a 72 system, no reboot,but can go into a fail safe, and if it's not set plane does what ever it feels like, no matter what you do with the tx. But weak batteries will cause a loss of transmitter range, or an rx to shut down because the esc or rx pack isn't providing enough power in them too.
If they are using a limited range tx, all it takes it a little too far out and bye bye plane. And the 72 can have hits/ interference issues.

So there you go, both sides, some problems that can happen to each, but since we are talking 2.4 that's all I listed originally. And who knows what rx they had? It could have been one of the old AR6000's with a 1500 foot range.
