Here is my scratch-built Bi-Copter doing flips!

I haven't seen any other Bi-Copters doing these maneuvers.

MultiWii Flip controller
17g metal gear servos
3000kv blue wonder motors
5x3 props
2 or 3s lipo.

Motors are directly mounted to the the servos, nice low slop setup.
Turned gains way down on outputs to servo driven channels (pitch and yaw on a bi-copter).

Enjoy!

I just finished building and flying this micro quad from BlueSkyRC. Clean!

Turnigy Multistar 1704-1900Kv brushless motors
Hobbyking 12a ESCs simonk
3s 460mah lipo
Multiwii Flip controller with Lemon RX

I built this multirotor using the Flitetest Anycopter hub and the new V-tail kit.

Flies great, pretty fun setup, easy to see orientation.

Finally built a mini tcopter and i'm loving it.

I enjoy building and flying multirotors of all different configurations.
