testing flight time and quality with various batteries

[larryleibo]

i received my 2 zippy 2800 s and my multistar 4000 and tested them
please not i have stock everything,except a tray for 2 batteries and i has a y configuration to hold 2 batteries, see image.
results

2200 single battery 9 safe minutes
2200 2 batteries on outside tray 18 min
2800 single 12 minutes
2800 2 batteries 21 minutes
4000 1 battery 18 minutes

by the way, this was the first time i flew without prop guards. it flies so much better without the prop guards, longer time and more stable.

Larry, what voltage were you landing at...was it always the same?

There you go Larry, start graphing...

I use 1.65 first warning
10.55 second warning
But I put another external warning light when any call reaches 3.70
So I have 3 warnings
I also took off prop guards and have even longer flights

I have never used prop guards, but I get 12 min till auto land on the stock 2200 battery. Is anyone else getting times like this? My first flight when I got it was 16 min till auto land. On my 1st flight I was just hovering around and going up n down checking things out. 16 min is still impressive with stock battery and voltage settings. Down to 12 min now and holding although I usually land at 11 min

I am around 11-12 min with stock and 2200 pulse. Don't k ow what the next battery will be the 4000 seems Nice. Is it more sluggish with the extra weight?

I would imagine it is more sluggish because of the extra weight. I don't have the advantage of being agile at my elevation. The air is so thin, the wind blows so much, and I'm flying quite aggressively (or so I'm told) that I can't really answer that question.

I do know, for my situation, the 4000 is a great power source.

FYI: It does have a bit of trouble discharging at the rate I suck it up. Sometimes I have to fly gentle to allow it to keep up. Great flight times though. Best I've found so far.

The 4000 will fit in the battery compartment with very little modification to the opening. Ya just need to find a way to keep it secured so it doesn't try to leave.

My vote is in favor of trying it. It made me smile

sorry for the delay in response.
the multistar fits in my battery compartment barely, after i dremeled the opening a bit , it fits nicely in the compartment but the door dioes not close well enought to make me feel secure
so i took a piece of bicyle inner tube and cut a piece about 8 inches and screwed in in under the camera housing and glued a jewelry clasp to the body and use the rubber strip as a safety strap.

i did see a larger door from shapewuys and considering buying it but dont buy it in white.
