I used to train flies.
A tame, trained fly is pretty rare. Most of them are wild, you know.
I’d teach ‘em barrel rolls, loops, landing on various surfaces, in various aspects. They were naturals at taking off, thank goodness. Didn't have to teach 'em that.
The hardest thing was teaching them to handle stalls. There’s a real aversion to stalling, they just wouldn’t do it.
Had to quit. It took about three weeks to really train one, they only lived 10 days. Was always behind the learning curve. (I think I also quit drinking about the same time.)
