Managed to get a bit done over the bank holiday.  All of the the control cables are now coiled and named, and I have a transport and work frame!  The castors should be here by the end of the week, so once those are attached I'll have a movable frame that I use to work on the cockpit - strip out, connect up the controls, sort out the pots, etc until I build the big permanent frame that will house the hydraulics.
