This is a Big Quad-copter! Bergen frame, made in the US. RC timer motors and esc's. Retro fit bottom plate for a 468 tall mount, with camera gimbal. This is a really nice unit for aerial photography. Will carry a smaller dsl with no problem. Tested with a Canon xsi. NO controller, or rx! I have a Naza... for the right price (188.00) i'll include it.
