Thrust, lift force, witch motor, battery and propeller ??? in the group ArduCopter User Group"Oliver I'm not an expert in any coptersbut let me put my 2c. Thrust is directly proportional to mass of air your prop is moving , since density is only .83 from sea level, they moving less air with the same speed of props which is limited by…"

What do you use the NIR camera for? Sounds very interesting project."

I already know this link but our precise specifications for 850Kv/880Kv and our propellers are missing. It give an idea witch is helping. My next step will be to experiment directly on site with different…"

I find this very helpful to play around with. http://www.ecalc.ch/xcoptercalc_e.htm
You can change motors props and batteries untill you find a solution.

Waouh, It encourages me to proceed. This also shows that i have probably an other unknown problem that causes my lift problems...
What about cold temperatures and batteries charge?
May you give me more specifications…"

"@Aaron,
Love your volcano copter! I've shown your videos to a few people as an example of people flying in very cold conditions."

I am also testing ArduCopter quads at high altitudes. I have flown the original ArduCopter 1.0 (before 3DR made a frame) and had good success with it on Mt Erebus, where the air pressure was about 650 kPa. See http://youtu.be/JYHDX6IE9-A…"

Torino....sei italiano?? direi forse francese...Anyway, I guess you could need to change also the propellers...you will need more thrust, i will suggest you to use more powerful engines with at least 12x4.5 props.
I have en hexa with…"

I order new 10/45 and 12/45. Today i will buy 4S's
I will make those experiences: at 2000m
1) 12/45 + 850Kv + 3S
1.1) 12/45 + 850Kv + 4S

Basic principle is increase P until it wobbles, then back off 20%.

- 3DR quadcopter for monitoring biodiversity in alps contest
SPYZ00 project
We are an italian aeronautical school.
SPYZ00 project consist in using the 3DR to monitoring the biodiversity in Alps Mountains.
The project is to using 3DR capacity to photographing regulary such spots to studying the vegetation and it's growing. Specialist noticing that the principal problem for biodiversity are the "miss-match". So that mean that such zoologic species are migrating or disappearing with vegetation changes. Actually they notice that some animals are migrating 200m higher in the Alps due to global warming...
Our first step was to studying meteorological conditions to prepare the second phase and flying a drone into mountains conditions.
