It’s the legs and feet. Our review of speed mods revealed that the most effective drag-reducing change that can be made to fixed-gear airplanes is an aerodynamic fairing over the gear leg and tire. Shown here is the Speed Pant fairing from Laminar Flow Systems, on a Piper Cherokee. On the bottom of the wing to the left of the Speed Pant is Laminar Flow’s fairing that covers the draggy flap hinges.
The implacable laws of aerodynamics mean it costs money to make an airplane faster. Fortunately, there are speed mods that won’t break the bank.
