I've just finished uploading a few new rocket aerial photos. Most of them are from a new payload design using an electronic timer. The timer was supplied by Daniel Franklin. Since it requires less physical space than the "servo and lever" mechanism in my previous payloads, I was able to fit the entire thing into a 2.6" airframe tube. This results in a more aerodynamic configuration than the previous boxy design.

Eventually I'll post some construction photos of the payload.
