Contrary to popular belief, the frontal area of an airplane is not the most important determinant of drag.
Vortex Generators and STOL Performance
One way to solve the problem of flow separation—and stall—is by installing vortex generators on your kit aircraft.

Certain situations and configurations just call out for a ducted-fan installation. Barnaby Wainfan explains the benefits and drawbacks.
Wind Tunnel
Seemingly inconsequential alterations—even mounting an inflight camera on the airframe—can result in big changes to an aircraft’s handling and performance.
Wind Tunnel
Builders are often in a rush to prove the airworthiness of their homebuilt projects, but thorough flight-testing is essential.
Wind Tunnel
Taxi testing may seem to be a mere formality, but it is a vital step toward bringing a new aircraft to flight, and is not without its dangers.
Wind Tunnel
Taking off in an aircraft would seem to be a fairly simple, straightforward maneuver. But in fact it’s complicated, and a combination of factors must be just right for it to work.
