So I decided to build a QuadCopter. Sure I could’ve gone to HobbyKing and bought a DJI Flame wheel for all of $12, but where’s the fun in that? Instead I’ve been a reader of the FliteTest blog for a while and came across some pretty simple plans for a folding Quadcopter: The Black Forest Quad.
I’m also a big fan of the whole DIY aspect of the RC hobby so this fit right in. The guy’s build in flite test is way cleaner than my own, but it still get’s the job done. I’m using the HobbyKing KK2.0 flight controller currently with this guy. I’d like to upgrade to a better board with GPS and more programmable features (MultiWii Pro), but I just want to get the hang of things first with the KK2.0.
First flights went pretty well, It took a little tuning with the PI controller (Who’d think the most boring subject from Engineering school is actually very practical and useful). I took it out to a bigger field to really test it out, it has a TON of power. A little too much in fact, I gunned it one time and the controller thought something else was happening than the quad going straight up and the thing flipped and crashed (woo first crash!).
Q Brain 4 x 20A Brushless Quadcopter ESC 2-4S 3A SBEC
ZIPPY Flightmax 2000mAh 3S1P 45C
4 x Turnigy D2836/11 750KV Brushless Outrunner Motor
Hobbyking KK2.0 Multi-rotor LCD Flight Control Board
1045 Slow Fly Electric Props (10″ x 4.5 deg)
1/8″ Plywood for frame
3/8″ Wood Spars for Arms
M4 Bolts and Nuts all around
And that’s really all there is to it. Total cost was around $130 or so. The arms and props are pretty break pretty easily by design. Those things will break, they’re cheap and easy to replace and save the more critical components. I still need to make a better mount for the receiver, protection for the board, and a few small other things. Eventually I’d like to mount a camera and FPV gear once I start getting things dialed in.
