Magical frames? Sounds like DJI was involved.
Can't you just use less arms and mount stuff into the hex-holes in the center board instead of octo-holes?

Hi Koolkikikat,

I'm sorry, I didn't weight the frame. I already put it together.
The frame is very stiff, not to much wieght.

You can see my hexa in this video at 0:28seconds):
Teaser Riverstone (2 min 56 sec)










Don't mind the discription at goodluckbuy. The octa is a octocopter and you can not use it as a hexacopter. If you want to make it as an hexacopter then you need to buy the hexacopter.
If you still want to turn the octa in a hexacopter then you need to remove two arms like I did.
It looks like a reall spider now, accept for the two missing arms. ( a spider has 8 )

You don't feel is in the flight charastics, and you now have a clear view in front of it.

I bought this frame at GLB http://www.goodluckbuy.com/professio...wheelbase.html I just starting building it last night. What sold me were the 22mm tubes. I cut the tubes so that I'll have a 800mm wheelbase and can use 15 inch props, which I also bought at GLB http://www.goodluckbuy.com/1540-15x4...r-2-pairs.html

I'm very satified so far. Someone here was saying that the CF frames at GLB where just CF veneer on GF, but I can faintly see the CF weave pattern on the inside of my tubes. I can't say about the bases plates as they are finished on both sides.

My frame, without motor mounts, battery plate and landing gear is 535g

Nice Remy, 1st pics Ive seen of the GF version, cant beat the price with the carbon twice as much and 100grms less, the GF version is much better value!

Jab, you did a great job with your Octo setup and your video was worth a thousand words.
I have a big 800mm CF Hexa on the way and a 3-axis gimbal to fly a Canon 60D. Do you
think that I would be better off using the 4822 490kv which will give me the option to go with
4S to 6S depending which size props give the best lift performance?

Should work.. Assuming 15" is ideal on 4S and using linear math you get:
4S - 15"
5S - 12"
6S - 10"

But considering the 490kv motor is running cold to the touch with 15" and 4S, I am guessing 12" and 6S would be fine. 13" might be pushing things a bit.

Jab: What flight time's do you get on your setup... ?

Got a spare AV130, some 40 amp esc's and WKM that I am thinking about putting in the same setup as the one your are using....

Thanks

I just got my new 4S 8000mah batteries, so I haven't tested them yet.
But I got 10min flights testing with 4S 6600mah and no payload. AUW 3.8kg and landing at 14v (3.5v cell). So depending on how much overhead I get when I add payload, I estimate 15-20min flights using 4S 16000mah and AUW 6kg.

My " Fake" cinestar Copy Clone BARGAIN


I thought id chip in to the snobbery argument about " Fake frames".. I bought the carbon (Fake carbon) Whatever frame and think its a steal for the price. Concidering the truely rediculous price the cinestar frame is , and for what extra.. a few bits of rubber damping.. woweee.. any one with an ounce of common sense can add a plate with some dampers on it to the frame and get a great frame for a way less than the cost of th e cinestar and enough change to stick a DJI wookong on it.. Yee haa i love mine, and as im not planning on working for steven Speilberg any time in the near future its plenty good enough for my needs.. But hey if you have money to burn follow the sheep.. Err I mean crowd and buy a frame that costs 3 times what its worth and leave the bargains to us cheapskates, who will be laughing all the way to the bank..

Oh and it flies too...

Can someone tell me the thickness of the tubing walls and base plates on the "fake" frame. I'm just curious because the Cinestar frame, of which we have built two for customers, uses 4mm carbon plate for the base plates and tubing with 2.5 mm wall thickness. They tubes appear to be spiral wound with a cloth outer layer. Pretty good stuff.

Nice video and photo.

Regarding motor mounts that clamp on to tubes - is there a trick to making sure the mounts are all in the same plane, perfectly perpendicular to the ground? In my case I had to mount the motor to the mounting plate before I could mount it on the tube. So I couldn't use a level. I just made sure that the ends of the motor mount bolts sat flat on the floor. But I was wondering if there is a more precise method.

My fake frame uses 22mm by 1mm thick tubing, and everything else is 2mm thick. I can't imagine needing 4mm thick, but 2mm thick tubing would be nice.
