@Adam, please click the part names above for product links. I didn't calculate the cost because i'm producing the frame and controller(+receiver). I had to buy other parts for testing my equipment.

Something should be is wrong... I own this motor, with 5x3 prop it is not even able to hover its own weight.

At HK the recommended prop is 7x5, which is right. 

Maybe you power it from 3s?

Hi Renato,

No, I'm sure everything working with 2S lipo battery :)
At first balance all motors before usage, bearing resistance is important these small size motors. Then use new HK 5030 props, not old GWS 5030 props. They are better as tea spoon, not as propeller :))

That is really awesome!

 

I was thinking maybe you could go with a lighter, more aerodynamic frame design like this http://www.rcexplorer.se/projects/miniquad/miniquad.html  (scroll all the way to the bottom for the final frame design).  And there's at least an inch or two of motor wire that could be shortened, not that it's much. Of course, for someone wanting a mini-quad to lift just a gopro... use the KK board, it's light and uses very little power, and you can use it for half the hub if you're willing to hot glue or epoxy it to the arms.

How is the quality of these new 5" propellers from HobbyKing? Are they well balanced? The fake GWS 5" propellers they had before where very very bad!

@Flying Monkey,
My setup is 140gr and including 50gr battery + 15gr antenna and connectors, this is less than you suggested :)
OpenLRS Multi board including receiver and controller and weight is only 7gr ;)
I'm using 16gr version(20gr with antenna) of it now, I can remove these extras.

@Jan, Quality 10 times better than tea spoons(gws 5030) :)
But already have a very small balance problem. I balanced all of them with 10x10mm size 3M transparent paper band. And they are very quite and efficent props.

I wasn't suggesting that the AUW was lighter... but that his carbon frame might be lighter than a flat piece of wood. Your arms look shorter too so his frame might of shed some weight there.  I do like his idea of using magnet wire for the motors.  What frequency is your antenna? Is it something that could be remade as a dipole? My homemade antennas are definately lighter that the stock ones I usually get.  Integrated LRS receiver and gyro/accelerometer control board? Wow, I gotta check this out...

Hi Melih,

I have one question, how do you attach the propeller to the shaft of the motor? "as far as I can see in the photo, you didn't use the propeller saver" 

Regards.

@Flying Monkey: It is UHF(433) antenna but it is working with piece of wire without antenna in few hundred meters

@Juan: These propellers coming with 1.5mm reference hole. I used 2mm drill for changing the diameter first. Then i used very very very(very) small CA drop for fixing it on the shaft.

I forgot to sharing my first flight video :)
