I discovered the marvelous "HORIZON" mode on MultiWii flight controllers. So much fun I built this 330mm quad solely to explore it. Great fun; a bit hard on the equipment (at my skill level).
Equipment:
F330 Glass Fiber quadcopter frame
HobbyKing MultiWii 328p
Turnigy 9x (flashed w/Open9x)
Frsky w/telemetry
4x D822/17 Brushless Outrunner 1100kv
4x HobbyKing F-20A ESC (SimonK flashed)
Turnigy Nanotech 1300mah 3s LiPo
Filmed with GoPro Hero3 WE
I created this video with the YouTube Video Editor (http://www.youtube.com/editor)
