Drone 1-2-3: An autonomously flying wing glider

Drone 1-2-3 is a glider drone based on the Alula urban flying wing (parts already there), a Walkera WK-2801 PRO R/C (in my attic) and an Arduino based auto-pilot for stabilization and navigation.

So far the only parts that needed to be ordered were: A Mini APM v3.1 (ArduPilot 2.6) and an external compass/GPS (Ublox NEO 6M GPS HMC5883L). Total costs: Less than 47 euro, including (free) shipping and (delivery free of) taxes.

Steps in this project:

1. Build the plane (trim and fly)

2. Make it remotely controlled (R/C)

3. Teach it to fly autonomously


The secondary goal of this project is: Extended flight time (longer than a day?). The coexisting primary goals are planet domination, colonizing of space and sheer fun.


Feb 16, 2015 - R/C equipment tested - Check!

After not using it for 5 years, the Li-Po battery pack of the transmitter was showing no signs of life anymore. Luckily I found an AA battery holder for 8 cells to replace it. For the time being that will do fine.

The (less critical) Ni-MH receiver battery was still in good condition. I charged/discharged it a few times and it holds approximately 286mAh x 4.8V (which is okay for an advertised nominal capacity of 300mAh).

Everything was connected, switched-on, binded, and worked fine :-)
