These are my FAVORITE!
I just remember, left aileron, right rudder....you should be lining up with the runway out your side window. There is a "v" in mine in the corner, and I use that as my visual to follow my track all the way down.
I straighten out right before roundout and flare.....
I was afraid of cross controlling with these when i first did them - just watch your a/s.
I would also go up and just practice a TON of short approaches with these!
Congrats on your upcoming checkride!
