If you know how you might post them here.
Might help others.

I had an issue once with the switchglo. Had to get another. Not saying this is your problem but since you have one you want to look at all possibilities.

I wonder how a Switchglo could cause glitches?

Mine is just Y'd into the throttle.

I wonder too. Talked to them and they had me send mine back. Got a new one. Problem went away.

Mac : I have one / or had one of those switches in a Fatti : spooked the heck out of me do to the low budget dipped vinyl insulation and the kung foo wire under neath it : Even the charge portion of the switch inside the ribbon contractor

Just my two cent's : The insulation is soft, paper thin, I had several component's that used the same wire - spooky

I was alway's re working component's do to that funky stuff. Vibration, fretting, shrinkage, black wire disease, poor solder joint from low lead solder substitutes.

Every thing from on board meter's, servo tab's, pin's, you name it.

Stuff is like a ghost. Think your answer is inside that piece of High Quality -

My mate had signal problems when doing pre flight checks turned out it was the switch glow....

Is the switch glow adjusted that way that it kicks in below a certain throttle or only for starting?

If it kicks in on low throttle generally it might have drawn the voltage temporary down and led to the vbar reset.

Lets make it clear, Switchglo is only a suggestion to check. Once mine was replaced, I installed the new one in the same location and it has been flawless for YEARS. I just fired my 600N and flew it the other day.

I'm looking for the emails I sent to Switchglo. It was really a long time ago and haven't found anything yet. If I remember correctly it was causing some servo interaction.

It wasn't an intermittent problem if I remember correctly. It was messing something up as soon as you turned it on.

3 year with my 700n, no switch, no regulator, no problems.

What I did was run a lead directly to my RX from the LiFe pack but the positive lead was ran down to the landing gear leg. I then put in an EC3 connector. To turn on the RX, I plug in an EC3 as a jumper.

No switch to fail, no regulator, cheap, light, reliable.

that is the route I took with my LiFe, except I used a deans connector.

Its all earth!

Ernie,
Over the years I have found that simplification to the power system is the key to a long life. THe elimination of small switches and such just keeps one more small part out of the overall equation. Even if you take apart a "heavy duty" switch, you will see that they are very fragile and with the vibration on a nitro, you are just asking for it.....just a matter of time.
In my Avant, I went with HV servos and a 2s lipo direct with a Deans plug.....never had any issues. Now I see you may not be using all HV servos so a LIFe pack would be the way to go or the 2s and regulator route. Personally if I had to choose, I would go with the LIFe direct....not because I don't like lipos (I love them ;D ), it is just that is the least amount of wiring and things to go wrong.
If the VBAR saw a low voltage situation, it would freak out, just as any other piece of electronics trying to operate below its operating voltage and when that happens, ANYTHING goes. You can never predict the behavior of a piece of electronics IN a LV situation.
Get rid of all the switches (ESPECIALLY the one that welded shut, which means there was way too much amperage being pulled through it) and go direct connections. You will be way happier for it.......Ron

After reading this entire post, I would recommend you not fly that battery again. Find someone who has a Radio West Mountain Computerized Battery Analyzer (CBA) to test that battery under load.

I have one that I use to test all my batteries. After their first charge I discharge them using the CBA and I file the graph. Once a year I go through all my batteries and compare them to their original graphs. Or when I suspect a bad battery.

The switch was NOT welded shut.
Every post is important in these type of threads.

Thank you all for your tips though.

Not welded shut but you did describe faulty operation. Does it look like the internal parts are worn or melted or anything. I'm only asking as I think it would be nice to know the true cause. Might be worth your while to try to duplicate the failure if that's possible anymore. As mentioned, there are a lot of suspects.

As for the failure, here's some things that stand out for me.
The switchglow was indicating LV.
The battery was near full charge.

1. loose connection in battery or very high IR.
2. loose connection in switch
3. something drawing excessive amps. A fully charged lipo should be able to supply enough amps to make some serious heat in those little wires and switch. If nothing was hot or melted and you verify the battery can supply good amperage, you might rule out excessive current draw....and also rule out everything downstream of the switch.

Assuming it was the switch, if you are set on using one, you might consider getting a good quality toggle switch. Not out of the hobby industry. Or, just use a plug outside the canopy. Adding parts increases probability.

I had both of the Hobbico life packs that you use fail under load. I no longer use them any more. One of the cells would play up and not hold a charge and then fail under load.

Dont know if you found I cause but just letting you know.
