The rig flew:
and I noticed a fair amount of swing on the camera, on this 1st flight I got a batch of blurred shots with the basic Auto setting- the default ISO being 200 which slowed the shutter too much. I flew a Didak Explorer 2.7 which was pulling very hard in a 14/15mph Southerly.
For safe transport I cut a ply board to protect the rig, I found it fits nicely into a ipadmini sleeve. The shutter servo is velcro’d onto the rig to keep it flapping loose.
