Ok, so “we” is really a couple of stunt pilots, some vintage aircraft enthusiasts, and a handful of Russians, but even so, they’re still around.
Don’t get me wrong, I love biplanes as much as the next guy, but I’ve read about the inherent inefficiencies they have- the obvious one, more lift means more induced drag, and how the wings disrupt each other’s airflow. This means a monoplane of similar build (but with different or more wing, though) should do better at EPA mileage tests than a draggy biplane. Of course, this is still information gathered mostly from the intrawebs, but it seems legit.
So, why do we, who live in the modern world of Sukhois and Extras, still have Pitts raising hell in heaven? Instead of dropping in a turbine in your An-2, why not get yourself a Twin Otter? Are these double-decked pilots hiding something from their mono-winged bretheren, or are they just clinging to romantic views of barnstorming?
