I was taught to fly polyhedral gliders with rudder and spoilers on the left stick and elevator on the right. That way I can have my left thumb on the stick when I launch. If something goes wrong just after releasing the plane, I don't have to hunt for the stick before making corrections.

This worked so well that I continue to fly all my gliders that way, with coupled ailerons/rudder or just rudder on the left stick with the flaps or spoilers.

Having the elevator on the right stick by itself makes it easier to keep the airspeed right when I circle in bumpy air.

I fly power planes with the normal mode 2. It took me a few flights to get used to mode 2, but switching back and forth hasn't been a problem since.

I'm a bit hesitant to fly someone else's glider if it's set up mode 2, though. I have to make believe it's a deadstick power plane.
