Building/finding 2 pound-Carrying Quad?

Hi there!

First, I'm a newbie to this forum so I apologize if I did something wrong. All forums are different.

I'm here because I need help finding a quad, or figuring out the parts I need to build a quad.

I want to be able to lift 2 pounds(Or as much as possible)on top of the quads weight. I have found some parts, but I feel that the quad would be a little big for my second quad. Those parts are here: custom Quad Parts.txt
And Help finding parts is appreciated.

For a prebuilt RTF, I want GPS capabilities if possible. I was looking at the Quanum nova, But couldn't find the max weight carrying limits. I want to carry close to 2 pounds, so it may not be the Nova. http://www.hobbyking.com/hobbyking/...Waypoint_QuadCopter_Mode_1_Ready_to_Fly_.html

I want this to be under $300 for the build, and can give a little for prebuilt ready to fly model(with transmitter).

BUT HERE'S THE HEAVY HITTER. I want to be able to control the quads board with an arduino style micro controller, in place of the receiver. This may be a problem for RTF quads, But any AMP flight board is compatible I believe.

I appreciate any help I receive.

Thanks,
Technopro

Hi mate what you need to do is the weight of the quad plus the weight of what you want to lift then add 1/2 again, then divide by the number of motors ,this will give you the figure of how much thrust each motor must make to lift ,so 6 or 8 motors may be a better way to go once you know how many motors you need it will be easier to find the multirotor for the job
 
Thanks Holtneil. I did more research and I'm building up a plan towards the use of the AMP 2.6. I am looking into propellers(13x10) and prop mounts.

I believe the quad will be about a KG and a half(about 3 pounds max.) with a payload of about another pound and a half max. I need to find what the thrust generated is. Would it be this number at the end of the stats?
Motor: NTM Prop Drive Series 42-38 750kv
Prop Tests:
13x10 - 11.1V - 344W - 31A - 1.79kg
13x10 - 14.8v - 740W - 50A - 2.8kg
14 x 6 - 11.1V - 403W - 36A - 2.23kg
14 x 6 - 14.8v - 785W - 53A - 3.05kg

Thanks,
Tech
 
Hi Yes , the first number is prop size, then battery volts , then the watts used ,then amps used ( max power test normally) then its thrust
Batteries are a 3 cell then 4 cell , the only thing i will say about the NTM motors they are nice and powerful but they are not light , I had some 1100kv on a 450 quad it would go from on the floor to 80 feet in 3 seconds but eats battery
If you go with the motors your going to need some mega ESC the max will be about 60 amps to play safe
 
Hi my quad is 700mm and i use 650kv heavy lift pan motors and 14x5.5 props , low kv motors will spin a bigger prop, a high kv motor needs a smaller prop, what happens is the same as a 4 bladed helicopter head ,if the rotor speed is fast the following blade will not get any lift due to the air its hitting is still dirty from the from prop, so if you spin a bigger prop at really high speed you will not get the full lift ,and it will eat battery power , take a look at some of these motors Tiger motors aka T motors, Agm and emax same just different name , sunny sky , may be look at a lower kv with the max size prop you can fit on the frame
 
Thanks for the help so far!
I was looking at this frame:
http://www.hobbyking.com/hobbyking/...ber_Quadcopter_Frame_550mm_US_Warehouse_.html
With the NTM Prop Drive Series 42-38 750kv / 785w, spinning 13x10 props on a 4s battery. Frame says it can take up to 11 but people claim it can do 13 fine. Opinions?

Any 13x10 props out there? I cant find any on hobby king.

With this setup, I can add skins and other equipment to it and still have plenty of maneuvering.
