How to fly a Spit 1a correctly!?

[reflected]

Hi,
The 1a has about the same speed as the 109, at least it had IRL.
I have no such problems online. Always close the radiator until the temps go too high. Trim the aircraft so that you don't need constant stick input. Use 3000 RPM for combat, 2,850 for power climb (I sometimes use it in combat too), 2,600 for normal climbing, and 2,100-2,300 for cruise.
When you maneuver in combat, don't pull the stick all the way, because you'll bleed energy. pull it only just as much as it's needed.
