Not CX but here goes. Passing 10000ft I removed the weight (sorry mass)/ speed flip cards from the bulldog clip and placed them on the pedestal as per normal. Capt tells me to make sure I hold the bulldog clip open so I don't ruffle the edges of the cards. I understand he is now a very famous trainer in FR.
The same gentleman was somewhat nervous should something go wrong and a little lacking in real technical knowledge, I suspect that may be in common with some of the STCs mentioned here.
