Some months ago, Dario Lopez, a local director calls me to take some aerial video for a short film he was developing... Of course I said yes!!
Before the filming, we were talking and he explain me what he wanted. It´s a funny short film (a "crazy" charlie's angels version) and he wanted to use a GoPro camera (at maximun FOV) for some action sequences with a jeep.
I decided to modify a quadcopter frame for this task because we wanted to have a clean images (with no motors, no arms, no props, no landing gear) and achieve this with a GoPro at 720p in a quadcopter is not an easy task. I made an asymmetric frame with the front arms at 115º. With this angle and the camera tilted down slightly we could get "clean" images. I needed to move back the battery to adjust the C.G. and I needed to adjust the PID values with the pitch axis a bit higher than roll for compensate this config. But the overall result is that the quad flys very well... I used original arducopter parts (plates, short arms, motor mounts and battery mount).
Thanks to Dario (the director) for call me because it was a nice experience. It was very funny to be the aerial camera following the director instruction :-)
And the work finished in a spanish way with a fantastic launch...
