Haven't owned one, but flown in them before.
Pretty much, they're all about yelling, "wheeeee"
or earning your wings along the way to fighting western imperialism. Looks like Western imperialism won, so yelling whee is pretty much it.
The air thing seems to be the big headache. My mechanic owned/works on a lot of these. From all I can see, they're built like an ox or water buffalo or whatever the soviets would say.
