Guys,

Does anyone know what it means when my AR7600 and remote Rx flash orange blips after being power on. I've even seen the Rx go solid orange and the remote Rx flash orange. However, most of the time it's both together. I'm wondering if I'm getting some interference from inside my home? It doesn't always happen.

I'm not referring to the fast flashing prior to binding. The Rx has already been bound. However, when I rebind, it goes solid everytime. It's after shutting down the power and powering up is when it happens.

The battery has plenty of charge. I am running Deans plugs with no switching harness, but I'm careful when plugging them together.

Any help would be greatly appreciated

Turn your TX off while your heli is off then you will have a solid LED.

Blinking indicates the loss of signal on RX.

This is very nice tool for signal loss trouble shooting tool while you are flying.

Not quite true. The flashing orange means loss of power (it has nothing to do with loss of signal). You actually caused the loss of power by switching the Rx off and turning it back on. (Power went to zero for some period of time.) As dalong2362 said, if you also turn off the Tx then power everything back on, all will be fine.

The intended purpose is: Before a flight, turn Tx on then Rx, all lights will be solid. After a flight, if the orange lights are flashing, it indicates that the voltage dropped below minimum level during the flight.

The problem is the electronics cannot differentiate between what you did and the problem it is meant to detect.

I had that problem even tho I did the proper turn on sequence.
Turned out the servos pull a hefty slug of current during the initial power up and the current surge over long wiring from battery to recv caused a short power drop. My solution was to use heavier wiring and deans connectors, and no switch.
If this is an electric with a BEC, use heavy wires from BEC to rec.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I'm rather sure I have been powering off my transmitter after powering off the Rx, then powering up the Tx again before powering up the Rx. Hmmm, I suppose I may be making this mistake. I do recall trying to repower the Rx without powering down the Tx in order to try to isloate the problem. I'll retest tonight..

GyroFreak, was your problem consistent? Meaning did it happen upon every power up? I actually shortened all of my servo wiring. However, the only long wire (about 8" to 10" long) extends from my ESC to the Rx throttle channel.

I'm running 3 digital JR micro servos for cyclic, a logitech 2100T gyro along with a JR tail servo in a MiniTitan E325. I'm also running the stock motor and stock ESC with integrated BEC. This equipment is being powered by a 3C Lipo pack.

No, it wasn't consistent. Maybe 2 out of 5 would blink.
Try using heavy duty servo wires from your BEC to recv, or just shorten it for a test if possible. 8 to 10 inches with small servo wires could be a problem.
It's worth a try and easy to do.

By replacing the servo wire, do you mean try replacing the throttle channel wire that came equipped with the ESC with a thicker gauge wire, all the way to the Rx?

I may first try to power everything up one channel at a time. Meaning, first I'll power up the Rx without any servos or gyro. Then add one channel at a time.

Does anyone know if my home wireless router could be causing the problem since it only happens upon power up?

Yes, but your method of testing without servos would be much better to isolate the problem.
My BEC on a gasser was different allowing separate wiring, yours has the wiring already installed from the BEC to throttle. So hopefully that is not the problem.

Hey guys,

I have found that if I power off the Tx after powering down the Rx before powering up the Rx again, no blinking. However, the remote Rx has flashed yellow minutes after seeing a solid orange on both the Rx and the remote Rx?

I'm also experiencing a strange issue the AR7600 and my gyro. It's a Logitech 2100T that utilizes a setup mode that recognizes your Rx. For some reason, the Gyro is seeing the AR7600 as a JR Rx??

To be sure it wasn't the gyro, I plugged a AR9100 into the Gyro and the Gyro recognized it as a JR Rx, like it should.

I'm thinking I need to have a chat with Spektrum...Oh great, I can't wait to sit on hold for an hour. There customer service is really begining to blow!
