Ok, you have got me worried. I have about 45 hours tail time out of 800+, and fly about 10 hours tw a year. I have never learned to wheal it on, despite having checked out at a number of clubs with a number of instructors. When I have asked, most people take the view it is not done on the sort of a/c they have. I have very little problem landing 3 point on tarmac up to 15k cw in a Jodel, and have recently managed 13k no problem in a Cub on grass.
Two questions;
What would I gain from doing a wheeler?
How long will it take the average pilot to learn?
