Gloster Gladiator was the last biplane fighter aircraft of RAF. Its first flight was all the way back in 1934, but it was still in service during early WWII - though even before the war it was actively being replaced by Hurricanes.

Elevators are bigger than on the actual plane due to mass distribution problems - with historically sized elevators the plane slammed its nose into the ground 50% of the time after touching the ground, and even the slightest touch on the brakes would instantly flip it over. Despite my best efforts, it's still extremely prone to flipping over, so use brakes VERY carefully.

The plane is very maneuverable but is very prone to stalls and constantly pitches up without trim. Be careful with the controls.
