I have a new challenge for you all! I haven't done a challenge in a while, and probably not for WWII aircraft, so I decided to give this a go. So! here are the rules for the challenge:
1: No rotary Cannons(Minigun, so use the tank cannon with a caliber up to 50mm) or guided missiles.
2: The maximum engine count must be 2 engines
2a: The legacy propeller engine, known in the XML as Engine-Prop-2, would be considered forced induction, and one per engine must be used to consider such forced induction.

As the Messerschmitt Me-262 was a jet fighter, jet engines are allowed, but the only jets allowed are the Blasto J-15 and J-50s. The aircraft cannot exceed Mach 0.9@IAS(1,103 km/h, 595 kts, 685 mph), and past Mach 0.8(if you can XML mod) the maneuverability must decrease.

Maximum turret armament would be 2 wing guns(For XML modders, 17mm, or 1.34 wing gun bullet scale as the maximum bullet diameter)

Minimum gun armament to be considered a heavy fighter would be four wing guns and one cannon, or three cannons.

Challenge will expire on Veteran's Day, 2021, or if 10 aircraft are made in this challenge and I can access them based on the auto-credit.

How I will judge the aircraft:

I will test every single one of the ten aircraft made.

A dive from 20k feet to 5k feet, 1 point every 10 mph(dive speed)
A climb from that dive, and a point every 25 feet(to test energy retention)

Durability would be how many hits an aircraft would take before it can not fly with any control, or plummet to the ground. An additional 25 points will be given for redundancy measures(2 tailfins, placing fuselage blocks in other fuselage blocks and reinforcing the connections)

Then I will test in a dogfight in a list based on how recent the aircraft was uploaded. the aircraft with the most points wins the challenge, and will be upvoted and placed on my favorites list, the second place spot will simply be upvoted. For non-xml-modders out there who are looking to "Supercharge/Turbocharge" the aircraft, I will provide the "Superchargers/turbochargers" for you to work with.
