Good connectors but for what you are going to lift I would not trust it. I've seen S800s have the XT60 desolder from sustained high current.

Does anyone know if GLB removed the 25mm version of the octocopter from they're site? I cant seem to find it anymore, at the same time I noticed that omgfly has increased the price on theirs to $495.

Seems so.
But do you really need the 25mm version? The 22mm is plenty rigid enough. Using 25mm tubes only adds weight, and makes repair more expensive.

indeed it looks that 25mm is only in RTF version.

I bought the 25mm and indeed it seems to be overkill. 22mm or maybe 16mm should be more than enough.

500 bucks for a CF Octo frame? I'll take it! Haven't seen anything this cheap anywhere else.

Thanks Jab! I wasn't sure yet about which version to get, I figured the original cinestar frame used the 25mm so i thought of going with that. Im gonna be using dual 5000 6s packs and carrying a Canon 7D so I wanna be sure it can handle the weight. One other thing, are the kits sold at GLB the same as the ones from Omgfly?

As long as the frame is rigid enough, lift capacity is decided by motors and propellers. Lifting a camera like 7D is what octo's are "made" for.
Judging by the pictures, the omgfly frame and the goodluckbuy one are the same.

Very good quality, just had to pay 40 to customs with DHL.
Very interesting posts Papajeff, what flight controller will you be using?
And other question: is it necessary to flash the escs? haven't done that yet..
Hey Luciole, How did that booy 2 axis gimbal workout for you? Do you like it?

JetFire, I am also interested in finding out if Luciole likes his Booy 2 gimbal
from Good Luck Buy. I am so surprised that they have such a large selection
of camera gimbals and MRC products.

Not sure what motors you are using but if they draw more than 10a(guessing they are since you are using expensive 50a ESC's)you will melt that cheap distro board.

I take the distro boards (whatever make) and sand off all the plastic coating, then you are left with large traces of + and -

then lay gobs of solder all along the nice wide traces.... then you have a nice light efficient board good for lots more amps than originally designed for... how many amps? who knows but its loads better than before.

Indeed Papajeff, they even have one with the fancy white ball for under $400!! I did however end up purchasing the 2 Axis Booy gimbal for my Octo and hopefully should have it soon. But if you have a chance Luciole let us know your thoughts on the gimbal. Thanks!

Tony, thanks for the heads up on the power dist board. I'm using the HL 48-22-490kv motors which run
at <12A with a max of 17A. I never thought that I might have a problem with that $4.00 HK board. My
motor wires are about 16 guage and that is the extension size that I used and the 3.5mm gold pin
connectors were a perfect fit.

I did add solder to each (F) connector on the board and never thought that I could develope enough heat
to "un-solder" a connection. However, you ought to know with your MRC experience. Do you suggest
changing it out for another option, because I certainly do not want any problems like this with such an
expensive MRC.

Yeah, the ICE 50's are overkill, but with their new "multi-rotor" catagory on their Castle Link, I thought that
they would give me the ability to test using 4S to 6S and 10" to 15" props to see which combination would
be the best for this big Octo.

Jeff,
I'll be using the PowerHungrySystems Distro Board on mine. Although I am using eRC 25 motors and eRC 65A ESC's which will be more power.

Here's a link to the board. http://www.hobby-lobby.com/multi_rot...41392_prd1.htm

Hi guys,
well haven't flown it yet, I just received my simonk flashed escs and have to maiden my hexa now.
However I tested the gimbal and even though it's great quality for this price, it might need modification on the roll axis cause it's not moving fast enough (small gearwheel driving a long belt) so i'll either need a faster servo or a bigger gearwheel.
Also i'm a beginner at using belt driven gimbals so i've to find out the best way to stabilise it since I can't use the Naza gimbal outputs. For testing i'm thinking about using a plane stabiliser (Fy-20A) but not sure wether it's a good choice...
Some pics of my advance on this amazing frame:
