I am not going to completely give up on the Esky, just shelve it for a while. I have had a few "Eureka!" moments, but this bird seems to require them weekly! Given I am stuck indoors in a pretty tight area, the FP is the best use of my time for now.
I used to teach skydiving, and The Radd lessons are reminiscent of the course structure: Heading control, hover control, limited fwd movement, etc. Crawl before walk is necessary!
