Quadcopter Take Off

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:

Total$204.53 CAD
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.

LibrePilot’s easy configuration.

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!
