I just bought a ar 8000x rx from here that was brand new and never seen power, during setup on my machine I noticed that sometimes it would flash the rx light or the sat light and sometime both at the same time. I read all about how it was supposed to show that the power got interupted since the last tx cycle.

I just got done building a new machine and the first flight went fine, refueled and went back up, got about 300 feet up and 200 feet away and the machine rolled on its back and started to piro all the way down to the ground. Nothing I did had any effect. Post crash inspection showed battery level was fine and everything else appeared fine except for the wires got yanked out of the regulator in the crash.

On the bench the rx and sat light will sometimes both flash or just one or the other will flash even when you just turn on the tx and then the rx, other times it boots up just fine and both lights are solid. This is the same way it acted before I flew it for the first time. TX is a 9503 and rx is the AR 8000x

The AR8000 is supposed to be a DSMX receiver. Make sure the satellite connected to it is also a DSMX satellite. If the Satellite is a DSM2 version, you will have problems. You can't mix receiver/satellite types within the same setup.

The three-wire cable between the main RX and the satellite, if not properly mated with all connectors properly seated, can cause weird behavior as you're seeing.

You didn't say WHAT your power system for this set up happens to be, but it must be robust enough to insure that you provide adequate voltage to the system (remaining greater than 3.5VDC under all load conditions).

Caveat Emptor. Are you sure it was new and "never seen power"? It sounds as if you may have bought it used, instead of NIB.

The satellite is the one that matches the rx, it is dsmx.

The power system is a 2300 mah Life pack running through a castle pro bec that just came back from castle from being converted to a v2. Post crash the bec tested fine with the exception that the output power wires were pulled out of the case, and I am assuming it happened on impact.

As for the rx it was advertised as new and never used and appeared to be as advertised.

Two things:
1) The Castle BEC Pro is a crash waiting to happen.

It does NOT matter if the "factory" has checked it out. They are not mechanically designed properly for strain relief on the output wire.
Your wires broke off on the bench before you even got to the field.

2) You don't need a BEC if you have LiFe - their output is low enough to run 6v rated servos directly.

My guess is that one of the output wires were broken and you can't tell. And, the added "confidence" of having a "factory checked" BEC made you think that the BEC couldn't possibly be a problem.

In my case, the wire was broken, but the "strain relief" kept it from falling off. The butt ends of the broken wire would touch and allow the system to power up but the connection would open as soon as the rotor spun up due to vibration.

Too bad for you.

I would tend to follow your line of thinking, but the case on the regulator was broken proving that it took a good hit in the crash. I would like to believe it was the regulator as that would save me sending the rx to hobby services for inspection.

Well, I sent the rx and sat. into Hobby services today to see what they have to say about it. I am running futaba 9252 servos along with a 9254 for the tail so I need to run a bec until I update the servos on that machine.

my friends 700n just crashed running this same Rx. I think it was a lockout but I am not sure. But posted it in the radio thread.
