Multicopterbuilders, ((old school terrain surfing))

I have been flying quads for about 3 1/2 years now, way before there was such thing as a mini quad, we flew the tbs disco, qav 400, mb epic 380, qx9, which were all a ton of fun, I enjoy flying long lines, all most like stretching out a roller coaster, most this video was filmed in the San Andreas Fault in SO cal, and other parts was filmed in the Salton Sea.
