Well, as some may notice, some of my challenge planes might surpass the speed limits of said challenge because of its design.
Ex: My M.A Firefox
This plane surpasses the speed limit of the Advanced trainer challenge because of its low drag profile and low weight.
This comes because of my building style, for you to understand my style in fighter challenges I prior 3 things:
Low drag profile:
I tweak every detail possible to reduce drag in my airplane, such as Air intake design, fuselage Length and wide. Also I try to keep balance with the cockpit, so you can still use the plane like you where in a real like cockpit and still have the lower drag possible with said configuration.
Lowest wheight possible: Every pound counts, as a fighter, it must be lightweight to ensure good fuel economy under low fuel conditions.
Also this affects the acceleration, so I try to remove everything that is unnecessary mass, this goes along with the Drag model, to keep balance between a low drag profile and low wheight.
Maneuvrability:
I adjust every aspect possible to ensure a good turning radius without the plane stalling due to game physics, this covers the wings design, wing profile, center of mass in relative to center of lift and Thrust, Etc. Also I try to ensure that the plane can keep a straight line flight without need of keyboard, wich sometimes may conflict with the max turning rate possible.
And last but not least:Realistic wing design: If thres something that I love is making they plane flyable under real life conditions, such as max speed, wing stress, max G-force that the plane can support and wing design relative to max speed.
This sometimes may end in exceeding the speed limit of certain challenges, I hope you guys can now understand why my planes have inferior turning rate in comparison to others in the same speed conditions or completely the opposite.
