Well ya..but its not so esay to work with Carbon fiber. Lets see.

+1 very true

extra safety

After the results of the poll, am even more confused.
all have the same votes

Satyasir, if you were at my place, what would you have bought?

I believe in custom building. Till now i have built 2 frames 3 rd one i am working one from last 2 months. And its almost final i will start working on it in couple of weeks time.

please upload pics. i only saw first built of yours which is in the forum
and great. I faced problems with loosening of motorss. really a big issue. also problem with landing gear, how do you build that?

Sadly i did not bother to take the images of the second frame hence i dont have anything to share sorry

About loosening the motors use loctite, i used to face this problem a lot but then i used loctite. Which prevent the screw from loosening.

Landing gear: First i used the acrylic sheets to build the landing gear which was very awesome light weight and sturdy too. But sometimes it was very hard to cut them.

Then i discovered these http://www.hobbyking.com/hobbyking/store/__22995__Turnigy_Talon_Carbon_Fiber_Landing_Gear_2pcs_bag_.html which i used in my second frame and they where fantastic. I am planning to use either same landing gears in my new frame or the landing mechanism of the X525 frame http://www.hobbyking.com/hobbyking/store/__22800__Hobbyking_X525_V3_Glass_Fiber_Quadcopter_Frame_600mm.html

One question: why are you going into heavy lifters? why don't you first atleast try you hands on a small to medium quad? 450 - 550 mid size quads. Do you that, when the quad size is increased the after crash cost is increased drastically

My one suggestion would be to first try your hands on a 450 size quad get used to fly quad and then go for heavy lifters. You should know how quad behaves in wind. This is just my advice as i believe in doing things step by step. Please don't get offended

i dont get offended sir. I appreciate your reply.

Ya, I know I should go step by step. But as my quad wasnt soo stable, I am going for a hexa. I think I can do basic flying easily. my last hexa was flying okay as per the frame I built. ( the only problem was nowhere to put the battery and so you see the battery's sticker came off due to using tape)

I want to lift a small sony camera and I want to fly stable. so I went into heavy lifters.

My first built( which failed) and second build were quads only.  Kk2 wasnt a good board even though it was plug and play.
I now will order Arduflyer with GPS and telemetry from adiboy today or tomorrow.

I hope GPS will be stable. I dont mind wasting time in tuning PID because this project was initiated for learning and research.

By the way, are you ok with the batteries? they work perfect?

Haven't tested the batteries yet very busy these days. Work and Store have to manage both

okie.
so x800 is better or HAL?

x800 looks cooler! and it folds....

Rahul why you sayig that your first quad is a failure.. I am flying the similar quad perfectly now.. with cheap 18amp hk esc and kk 5.5 board..

x800. done then. sorry guys who voted for HAL and tarot

@arun bhaiya, well failed means, I couldnt fly it well and it wasnt very stable. motors had bit too much thrust for that frame,it flew to fast., right?
and you are a professional sir, expert at this, you can even fly broken quadcopter( kidding ) , you are good at this bhaiya
plz upload vids.

You are true a bit over reacting to the controls.. but I liked it very much.. good to learn as I am a beginner.. I can fly it without worries.. cost me only 5k to build..

haha. and to me it cost around 12k
where did you place the battery?

I fitted a 450size heli landing gear.. and fixed under..

okay bhaiya. great idea.

See i suggested you buy the x800 in the beginning itself, its a good frame according to reviews . And for CF it is quite cheap.

Ya, you win
But I agree with arun bhaiya that the landing gear is bad. looks like cheap 14$ one available on ebay

Well then you will have to take some landing gear building lessons then
http://oddcopter.com/2011/12/13/inexpensive-quadcopter-landing-gear/ - its for a quad but it will work, just use 7075(Very hard only machinable) grade aluminum if you can find it or T6061 grade(Quite hard but bendable by hand at high applied force, bout half your body weight to bend it(25-35 kg).

Even arun sirs idea is great and as i see you wont be using DSLR and stuff so way to go arun sir

What about this? with a gimbal.?
