The only good thing about that crash is that you unequivocally know 1) what caused it and 2) how to avoid it again. Many crashes aren't at all that straightforward.

I hate tear-jerker stories sorry for your loss, at least you are still in good spirits

When i check the voltage on my 2 cell lipo, what voltage should be the no fly volts? do you have too put a load on it to check it?

I check with a 1 or 2 amp load and call it quits at about 6.7 to 6.8 volts from a 2 cell lipo.

Saturday morning I flew my helicopter in my pajamas
How it got in my pajamas I'll never know

You hit the nail on the head there!

There is something to be said for the fact that there is no uncertainty. Just fix the problem and move on with confidence!

I crashed this same bird about a month or so ago. She was up high in the sky in my "playing area" and suddenly she started acting strange. She still responded to inputs, but I could not bring her back to the pad. Heck, I couldn't get her back from flying over the cliff!

I hit throttle hold, and she went to idle, but it didn't help stabilize her at all. So I aborted throttle hold and fought her some more. She was flying level and slowly decending over the cliff. After a while I gave up and hit throttle hold again. She hit the side of the cliff about 1/3 of the way down.

I got very lucky. Since she was level and moving slowly, when I hit throttle hold she practically auto'd in. Very little damage!

But the question on my mind, on everybody's mind, was what caused her to go in?

One of the few things that was broken/missing was one of the double links. Since the crash I've talked to numerous pilots, and we believe that somehow the doublelink came off in flight. That is why she was flying strangely, but still reacting to commands. One of the blades was simply weathervaning or whatever you call it.

Some of the guys said they have seen this before, and at a "normal" field, the pilot was able to bring it in safely - albeit pretty much where the heli was flying.

Anyway, there will always be that uncertainty on a crash like that. So the first post-crash maiden flight can make you quite nervous!
