>>991076>RadialsI have no clue, there's a bunch around here in the form of a few warbirds and a couple of Stearmans. But I doubt those or the Avenger and Sea Fury are cheap to maintain in general.
That's single engines anyhow, I know the Ju-52s solved their maintenance costs by having a lot of it be volunteer work. I wish I lived closer, apparently you don't need any prior training for them to teach you to work on those engines.
