Pros and cons

Pros:

• Good maneuvering energy retention
• Lower wing loading than its Allied opponents, allowing smart use of vertical maneuvers at medium altitude
• Easy to learn MEC with
• Can reach >500km/h IAS at sea level and with good use of MEC
• Near-infinite WEP with MEC
• Quite average in all aspects as a fighter

Cons:

• Doesn’t climb very fast
• Overheats quickly without MEC
• Ailerons compress seriously above 550km/h
• Faces many superior planes in an uptier - weaknesses of the enemies must be exploited to defeat them
