Site: Droptank Mountpoint Cost

Overview

Do the mount-points for drop tanks effect a planes performance? Lets find out!

Testing Parameters:

• Altitude 100-200 feet for all tests.
• Droptank (if equipped) dropped on runway before take off for tests.
• Plane internal fuel was 25% fuel.
• Smallest gun package used in tests unless indicated otherwise.
• Speed measured at edge of radar ring (some planes can go a few mph faster after radar ring).
• Wep used from start if plane had it.
