they are still working on that and no thats not correct.... Jani said in other post "ose 850kv motors with ArduCopter propellers can lift 433gr each motor with 50% throttle, with 75% throttle they lift 855gr. at 50% current was 3.4Amps with 3S LiPo, 75% 9Amp. (100% thr, 1095gr, 12.2Amp)"

so trying to stay at around 1:2 max 433*4 = ~1700g at 50% thrust.... and i believe with a normal 2200 battery they said its around 1010g built... so that leaves u about 690g easily to lift....

and the upgraded motors you can buy with the larger props push it to something like 4-5kilo's so can lift a good bit.... honestly though quads are meant for leight weight, i doubt anyones gonna be running 700+g cameras on their quad with the stock motors.

jani also said their waiting on all the final items to arrive for final weigh in... and lift characteristics etc.... it all comes down to flight time, battery weight etc on what you can lift i mean technically stock motors theoretically can lift 1095gr at 100% so 4kilo at 100% but you wouldn't have good control with having to keep your throttle near 100% just to generate lift.

Chris,

Thanks for the comment.

The number you've crunch is within the weight horizon I'm looking at for my setup.

I was hinging on Jani's comment in one of the post that says the arducopter was not meant for light rc flying (I took it as light weight) but for aerial photography (that's also where I got the figures used in the post you are commenting) so that's the history of trying to pin down the flying weight.

Incidentally, it took a bit of time for people to answer my post so I snuck into Mike Lombardi's post to hasten things a bit :)

Roger

I see there is 880kv motors available, what is the equation to calculate lift capacity
