Light 'n Tight - Av Bay Build - Wild Child

Did your main charge fire?

Mark, the main charge didn't fire. When I ran the vacuum test, it fired both times. So it should have worked.

So I took things apart and put a meter on the lighting device and it registered in the K ohms. Before the flight, it was about 2 ohms. So perhaps it burned but didn't fire the pyrogen. I also think that the little battery was at the end of it's limit, since it had already "flown" twice before it's actual flight.

I tried to launch it a second time, but I burned the igniter and then the MAWD started a continuous tone (low voltage indicator). At that point, I reluctantly called it a day.

Lesson learned: Fly the same battery once or at most twice, because batteries are cheaper than the rocket it is flying in

you should try a li-ion battery
They are very light (about 20grams) and reliable (I have done up to 10 flights without recharging)

Yes, batteries are cheap. One or two flights top. I also was wondering if you possibly broke a wire trying to get everything buttoned up in the av bay.

That's a possibility Mark. The frustration level was getting pretty high during the assembly, so excessive force was possible causing a wire break. I didn't pay attention to the beeps to see if there were three or two for continuity. Again, I'm so new at this that it's all part of the learning curve. Looking back on things now, just getting it back with no damage was somewhat amazing. There is no substitute for experience, and that is definitely true with flying dual deploy.

They look nice, but there is absolutely no volume available for a standard 9V battery in this av bay. As it is, the A10 battery barely fits.

A 9V li-po may fit, but I haven't researched them to find one that meets the voltage/amp envelope for the MAWD.

If anyone has a suggestion on one, then I'm open. Weight is not the primary consideration now. It's volume.
