A couple of years ago, I put together a quadcopter, but haven’t gotten a chance to play around with it. I decided to dig it out of the closet and hope to learn how to fly it this summer. It’s a 250 mm size quadcopter that is suitable for racing and acrobatics. The parts are the cheapest I could find on Ebay and Hobbyking:
|Glass/Carbon Fibre 250 mm Mini Quadcopter Frame Kit||$25.21|
|EMAX MT1806 2280 KV Motors||$46.54|
|4 EMAX 12A ESCs with SimonK Firmware||$51.05|
|8 pairs of GemFan 5030 Propellers||$17.36|
|CC3D Flight Controller||$20.11|
|Turnigy Nano-Tech 2200 mAh 35-70C 3S LiPo Battery||$26.01|
|ZIPPY Flightmax 2200mAh 35C 3S LiPo Battery||$18.25|
I also got the Turnigy 9X 9-channel transmitter ($140.16 CAD). It got the mode 2 version, but it’s not too difficult to convert to mode 1 controls, as I did. The mode refers to the mapping of throttle, pitch, roll, and yaw to the controls.
Assembling the quadcopter was not too difficult. As seen in the pictures below, I have the battery strapped to the top for now. LibrePilot is the open-source software I used to set up the flight controller. It has a very nice UI and makes calibration easy for someone like me who knows very little about these flying machines.
Did I mention that this thing is suited for racing and acrobatics? Because it’s not stable and very difficult to pilot! Larger quadcopters are typically more stable. I only managed to get it off the ground for a number of seconds today, and broke one of the props. I have a lot to learn!
