Yesterday we took number one son's home made tri-copter for another spin. Last time it flew very well, and so we thought we'd add a GoPro camera to see what kind of pictures we could get. We fitted the camera by the simple process of just sticking it on the front plate of the device. This seemed to work OK, although for the first few shots we had the battery wire in the frame.
Turned out that there was more than enough lift to take the camera into the air, although it is a tiny bit more wobbly than we'd have liked. The video came out pretty well, all things considered.
