RE: What to do with a "retired" trainer?
Trainers are amazingly valuable --- don't get rid of them!!!!!!! Eventually you will come back to these machine, when your skills are fully developed & your appreciation for them returns. New pilots get "bored" with trainers and start looking for the next adventure. When you've had lots of "next adventures" you will take another hard look at these wonderfull machines and start flying them again -- either in stock form, or as hopped-up fun fliers.
