Pete, I hadn't though of that.

I cycled the battery and it showed 112 minutes of charge left. After the cycling, the second discharge showed 120 minutes at 500ma, correct reading for a 1000mah pack. After the cycling, and skinning the cover off and checking individual cells, all were exactly the same voltage. I then plugged in a full complement of S3151 digital servos, seven total and set the transmitter on servo test. I let it run the servos for close to 20 minutes, I stalled one or more and even then I couldn't get the full red light. I could get a lot of yellows and a red flicker now and then, but that was it. As soon as I was through testing the servos, I took individual cell voltage checks again and I found two that were 0.13 vots lower that the other three. I don't know just what to think about this. The battery has been on the shelf for a few days now, so I'll check it out one more time. I still don't trust it at this point.

Conclusion is that I don't know what happened. Pete, thinking back over the switch as an issue, I'm not so sure that was the problem. For the failure I saw to be the switch, it would have to have gone bad part way down the runway, and then healed it's self. I've retired from the Computer industry, haveing spent 30 years in service. The switches that fail will always fail on make, or the toggle will break. Once they are made, they are good until they are turned off. That, and the fact that the switch in the harness is a DPDT wired in parallel, providing two sets of contacts, it doesn't seem likely that the switch was the fail point. Not impossible though. As I was writing this though, the thought of a broken wire would fit the bill nicely. Viberation would make the contact break and then a wiggle would make it again. I'll check it out

The plane is the first one I had built in over 30 years and there were a couple things in the linkages that I discovered I hadn't done correctly, IE the horns were to far back from the hinge lines. I'm taking this oppoturnity to fix all of this before it goes in the air again. I need to add the switch harness to my list I guess.
