Hi guys, im trying to sort out some power issues, with a 90 size, 3G ship.

What does it mean, when both the RX and satellite lights flash in unison ?

Is that a power outage ?

TIA

I would think that the rxs are not binding. Check your manual for possible remedies.

Hi Matey!

I read your problem on archeli, that's a real pain, especially when you just started getting the flybarless going.

The light's flashing is a brownout(Quickconnect condition) as opposed to an RX loss of signal(I originally thought it was caused by an RX loss of signal as well, but apparently not). You can verify it with the spektrum data logger. If you have a bit of a read on here where I was trying to troubleshoot the glitches I was seeing, you'll see a lot of people chime in on the different fault conditions with spektrum and what they mean.

You can get the lights to flash by leaving the TX on, turn on the RX until it connects. Leave the TX on, disconnect the RX battery and then reconnect it. Is this what your lights look like after you land?

The ONLY thing that causes flashing lights is a power outage.

Your battery isnt sufficent to carry the demand under load, or you have a bad switch or something.

Hi Brendon, cheers for that vid mate I was a bit vague on the quick connect /brown out thing. Ive been using spectrum for yonks now, and i dont think about glitches and lockouts and stuff..... it just works for me. This has been my first real issue. According to that vid, one of my AR7000s isnt quickconnect....like its supposed to be , after reterning it to horizon for the quickconnect update.......

Hi Barracuda,
Was using Ar7000 and FP 2500 2s...... ill try now Ar9000 and a outrage NRG 5000 mah 2s ......surely thats gotta be big enough..... The FP lipo performs great.....obviously not great enough tho
8 Amp dualsky reg sound enough ?....kinda starting to doubt it now

cheers

I'm just saying that glitches and signal loss don't cause flashing lights. Power loss does.

If you've got an adaquate power system (it sounds like you do) start looking for loose wires or bad switches, or something thats having a vibration problem.

Hi Chris,

The Lipo should be more than enough power, i'd check to make sure the wiring is up to the task, that maybe the bottle neck. How have you got the battery connected into the AR7000? The AR7100 should be fine as you have a nice big pipe to send the current through but with the AR7000, you probably need two plugs going into it from the RX pack (i.e you have a deans on one end, and two JR plugs on the other going into the reciever, apparently the pins on those things are only good for up to about 5Amps. If your running the align 3G with grunty servos, it's possible it's spiking above this as the servos work a lot harder to centre all the time. I watched this thing from finless bob on power systems which made sense (that is unless your running an external bus like the kiwi or reactor X)). Hope this helps matey, i'm sure your drawing a lot of current with the way you fly so it maybe your issue. Check the exisiting wiring and pins just in case as well. Here is the power systems link that I found handy as well:

It freaks you out a bit when you get a radio issue these days, I was getting used to not having to worry about it anymore until my recent problem!

The light on your rx will blink if you by mistake turn off the transmitter and then turn it back on while the receiver remains on.

You got it backwards.

It will blink if you turn the receiver off and back on without turning off the transmitter.

Like I said, the only time it blinks is if there's a power failure. Whether you turn off the reciever, or it looses power in flight, it doesn't know the difference.
