Smallest Quadrocopter with GoPro

Posted by Melih Karakelle on March 22, 2012 at 3:00am

Hi Guys,

The title is a little bit ambitious but i guess no one tried to lift a GoPro with a 140gr Micro Quadrocopter before :D

The throttle was %80 when flying with half drained 2S LiPO battery, this is why it is a little bit aggressive.


This is my micro quadro setup

3689448968?profile=originalController:Opensource OpenLRS Multi receiver with Gyro and Acc with onboard radio receiver
Firmware: MultiWii v1.9 (modified for OpenLRS onboard receiver)
Frame: MQ-200 microquad frame
 Props: HK 5x3 (black/red) props.
ESCs: FL6A Fast PWM 6A ESC (Hobby King 6A with firware update)
Motors: HK 10gr

Thanks 

Melih

    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 :))

    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?

    @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.

    Very nice.This is rather a GoPro with propellers

    Thanks guys :)

    @Sandro: There is the link of FL6A ESCs: http://www.flytron.com/multicopter-parts/178-fl.html

    We are loading Simon's ESC firmware on HK 6A ESCs. You dont need to buy from us if you have enough programming and soldering skills(pads very very small) , you can make them by your self.
    Standard and Fast PWM ESC difference is huge. My Micro Quad working with every PID value after new ESCs, I guess correcting the position before PID calculations require.

    Nice work! What was the total cost to build excluding the gopro?

  • John Moore March 22, 2012 at 8:29am

    Thats interesting. Im building (when the parts come in) a similar sized quad with the HobbyKing PCB frame and I was wondering if it could hold a GoPro.

    @Melih: That's super cool! When will the upgraded 6AESC be available again on Fly store?

    Thanks sergei. so this means, we can increase the radius a bit to make it fly around 50% throttle. 

    In a scenario like this, is prop size the fist thing we should improve?

    regards,

    Ruwan.

    @Melih, BTW forgot to mention in my last post, your video is great :)

    Cool!

    Ruwan: momentum theory says that theoretical hover power is proportional to 1/r (r being prop radius). Of course this doesn't take into account motor/prop efficiency.
