Thanks very much for the advice, everyone. I'll try all of it, but I'm
especially keen to see how 'right wing first' goes.



I can only comment re Discus. Ensuring brakes are unlocked has been
mentioned, but sometimes they will re-lock when first wing is put on, so
unlock again if necessary.
Fix stick central, I use seat back to hold in place.
I assume left wing first arose because of partly inserting locking pin,
with the handle stopping it pushing out again.
