Had a little fun flying in a local park here in Johannesburg, South Africa. Used a GoPro Hero on my own design anti-vibration mount and my quad running the newly released v2.5 firmware. Click on the photo to go to the youtube video.

Quad specs:

APM2

KDA20-22L motors from Hobbyking, 11x4.7 APC SF props

2 x Super Simple 25-30A ESC's from Hobbyking, two more on the way

2 x Hexfet 25A ESC's from Hobbyking (2 of 4 were DOA)

3S 3000mAh Turnigy 25C

X525 frame

    3692377532?profile=originalHope that makes sense Jonathan, simple and rough but it works great, basically a 10x10mm balsa beam with the camera attached below it, pendulum-like. The dowel stick is a brace to stop the beam (and camera) from rotating, all three contact points mounted on rings of soft car door rubber seal.

    No trouble with the KDA's so far, most others were out of stock at HK when I bought. Tried 3 blade props (see my other blog posts) but they were less efficient than the 2 bladers, so I don't think 2 props per motor would achieve much. Apparently 1 blade is the most efficient (with a counter-weight).

    Thanks Douglas, just one prop per motor, but interesting idea, the motor shaft exends out the motor but I've used the supplied adapter on the other side to connect the props.
