Today after about three weeks of false starts, I finally got everything sorted out so I could get Zog flying. In previous weeks, there were issues with holding Zog firmly in place, with a minimum of armature, which could be easily removed from the frame.
Magnets from an old hard drive hold the horizontal stick in place.
Glued to that stick is a stick terminated with an alligator clip.
Without the glue, the clip was bending under the weight of Zog down there.
Here are the frames taken today, more than half of which were removed / merged with others to make Zog fly:
