heavy octo for semi-pro and pro video gear - with arducopter

hey,

is there anyone on forum who have built (or bought) copter for carrying heavy-weight (3+kg) video gear and is using arducopter board to control it? Duran DeV is running droidworx AD8HL and i am trying to contact him to find out about his setup, but anyone else?


would anyone be interested in kind of .. "assisting the build", remotely?

what i need is advise on

- frame (so far looking at droidworx skyjib/AD8HLE, or cinestar 8?)

- motors for that frame (AXI?)

- powerboard (or esc?)

- props (size and manufacturer? i've seen more than one prop braking on my friend's MK, it's really f..ng scary when it happens 30m above the sea)

- i would really like to use arducopter instead of MK - small, compact and developing project (and cheaper, too) + strong engineering community

camera we are aiming towards is fs-100, which (with reasonable lens and battery) weights about 2,5kg..
camera gimbal - av200, no 360pan (at least, not yet).
flight time - 10 minutes in the air in reasonably chill weather would be great..

what did i miss?

budget for frame+motors+powerboards/esc+props should stay within .. ideally 3k€, and i'm located in europe (so when ordering something from USA/Asia i will have to add VAT 20% + custom fees, another 5-10%)

did i miss something? fpv gear i have, tx/rx will probably be spektrum dx8, and i can find good specialists in soldering/electronics (not that i would like to spend too much time in that area)

RTF packages on kopterworx (and anywhere else) are always running MK, usually include lots of stuff i don't need and are above my budget..

example calculation (based on kopterworx.com pricing):
frame: 1x cinestar 8 @ 1750€
motors: 9x kw4pro @ 80€
props: 5x 12x4,5 cf @ 79€/pair (no sure size is enough, but for price indication should be good, i suppose)
powerboard: 2x herkules II power board pro @ 499€

total is 3120 (tax deducted)..

it feels somewhat.. scary? to put tiny (reasonably cheap) arducopter in control of gear with flying cost a bit less than 10k€.. maybe what i need is a bit of .. confidence? :)

thanks in advance,
jk
p.s. in my fleet i have gaui330x to carry gopro, custom-built aluminium hexa (now dead due to frame failure) with arducopter, foxtech carbon hexa frame with arducopter, couple of light planes for fpv (hk epp fpv sub-2m wingspan etc), 450sized and micro heli's.. so i am not a complete beginner - but of course very far from being a professional..

Thanks for getting a SmallSpy Jaan!

As intended as a beginner's multicopter the SmallSpy has the same frame construction as the larger multicopters making it very tough for it's size. It was made lighter with 1.0mm carbon frame plates instead of 1.5mm plates. The landing gear is not as delicate looking as the larger multicopter gear and has also been increased in thickness to 1.5mm from 1.0 on the old version.

Yeap, there is not a great deal of room to neatly fit the four ESCs on this bird. I keep wondering if making the main frame deeper as I did on the larger multis will help. But then the arms will need spacers. Carbon arms will just push the price up :(

I've read that 11 x 3.8 props will give slightly more thrust than 12 x 4.5 as they spin faster. ;)

Hello Paul
The product listing and Assembly Guide for the MegaRadius Camera Mount are being finished in time for the collection of the carbon parts on January 15th.  There will only be 5 in stock and the interest is suggesting they are sold. There is currently no way of taking pre-orders or reserving stock. After that, the next batch will be collected in the first week of February.

I have completed a Megaradius and just need to fine tune things a bit. When I have installed it under my CC octo I will post another video with the electronics working.

so, a bit of an update and question, too :)

i went for cinestar 8 and cs 360 camera gimbal should be here in couple of days (just got email stating that it's shipped).

question - i do get it correctly, do i, that for different camera (assuming that everything else is same, just weight is different) i have to (slightly?) re-tune PID's, right?

is there any simple rule, like "you add weight - rate_p should go xxx up/down and stabilize_p should be yyy bigger/smaller"?

thanks,

jk

Do you know any thing about this motor? http://www.foxtechfpv.com/sunnysky-281411-kv-700-motor-p-382.html

thinking of using it on an oktokopter..

nope.

stuff i've been buying (so far) from foxtechfpv is not bad, actually - so it gives you some hope those motors are at least not bad :) but then again, it all depends on your goals.. i thought i wouldn't risk and went for axi's (but my goal may be very different from yours)

Hi,

which is more stable/better to fly 650mm or 950mm hexa carboncore frame?


My setup is:

- 880kv motors

- 12x4.5 props
