The only load which I have are mineral water bottles. they are made of PET so the weight is almost only the water inside. I just used the velco to tire them to the boom arm. I often do that for load test and also when i fly over water, i tired the emty nineral water to arms for saverfy just in case it have to landing on water.
I have a eagle tree datalog but it used the T dean connector and my octo used the XT90.

Hmm... Empty PET bottles when filming over water! That's ingenious!

Do up a converter connector.

Maybe coat the bottles with Rain-X .. increases surface tension to make lift-off easier .. less float "stickyness" (lotus effect), and droplets will blow off from rotor "wash". Not so critical for such a large build, but why carry around extra water

With such a huge investment there coatri, maybe a good idea to practice landing, and especially take-off, from water landings. Probably make for some uniquely interesting videos too. I'm really learning to appreciate the metric system .. one milliliter equals one gram equals one cubic centimeter .. making calculating float size versus water displacement really easy.

@prodriverex : I already do converter but busy at this time for filming in An Giang province. Will do test log on next week
@Tayninh68: I can do fly and take off Ok since I flying helicopter for a long time. The empty mineral bottles used as the life buoy in case it have accident in fly over water. This monster have long arms so the bottles are out of the props wind flow.

The otehr priblem is the arms i am using is the tarot 600 tail boom and it is feeble, with hight load it is vibrated. I am waiting for the carbon boom come (hopefully this week dual to terrrible service of POSt in Vietnam, they are in post office for about 2 weeks already but still their) and replace all the boom. Then I will redo all full load test with eagletree.

This is video we do with Y6 copter
Aerial Photography - Hexa Y6 (4 min 5 sec)


and this is the video make with this monster copter in Ca Mau Television station as the demonstration

I will do all the load test and flight time test.
The T3515 also good in 6S but I like the 5S with big carbon props :-)
I will update new test video and also load test by this weekend when I got time.
I do test the W48-22 also , the quad is ready but the weather .

This kit is 3.75kgs without battery anf the gimbal.It flys 20 minutes with 2 packs of 5600mAh 5S 25C GenAce make total flight weight of 5.3kg. I will do full load test by this weekend. The monster is on the way to DALAT city for some waterfall video capture.
Hi caotri.
What are your basic and attitude gains for the wookong in the above vid.

@Paul@SCC : do you mean the first maiden video?
The Basic gain is 135, the attitude gain is 120 as I remember. It has change when I put all the gimbal , camera on.

I decide to convert it to X8 for easier when taking it around for video. With to big size it is hard to bring it to the field and also the limited of license to fly this big object in my country.
Beside that the load is over the need so it will be convert to X8 or come to smaller Octo with props overlapped.

the YsX6 hasa more output for motor control than the dji. with octocopter it still have servo ptz port since the dji is not.
the YS X6 as my feelling is better than the dji in PH.
ysX6 also cheaperthan ths dji in waypoint option also. and you donot need to buy the ground station.

hope this can help

hi,
thanks for the information.

i am pretty new to the octocopter flying - but my background is working in the film industry as a cameraman and i want to built my own octocopter for professional use.

weight wise would it be possible to put a "red epic" or a "canon c300" onto the octocopter?
if yes - what would be an approximate flight time.
if no - could anyone advise me what to get to built a suitable octocopter.

any help is highly appreciated

thank you

this monster octo has do filming with sony fs700.
the red epic semm heavy so the flight time is short. however one derector ask me flight with red epic but i care of flighing with this super expensive camera.
I beleae that for the red epic you should look atbthe axi motor which is more powerfull and also super quality.

Hello Caotri. Exellent monstercopter. I was planning to build a big one my self, and serched the net for others. Then i found yours. The 21,5mm motormount blocks is a smart idea. I belive they are a littlebit smaller, maybe 20mm for fastening the booms tight? Difficult to find equal. Is it possible to buy a bunch of you? Or is there somewhere on the net i can buy them? If i count right, i need 64 pieces, 32 for the motormount and 32 for the center. Thats without spares. I'd like to buy more if there is a way to accomplish this with you.
Best regards André.
