Auto Credit Based on MetalManiac54's Old Engine Challenge [CLOSED]

I didn't saw any rules about parts except old engine, so i built this plane.

Only default designer's functions is used.
All characteristics is at 57 meters ASL while controlled by default ai.
Max speed is 401.65m/s (1446km/h).
Fuel time is 1556 seconds at full throttle.
These engines uses thruster settings, so it works like a jet, and can fly faster than sound without any problems.
Max sustained g-force is 20.

    @trios21 You probably forgot about wings.
    SP can't really calculate real-time aerodynamics, so it calculates very long expression, i proved that for std wing it uses aspect ratio and airfoil.
    I'm still not sure about reynolds number, because most of numbers is pre-calculated in designer, so probably it uses chord instead.
    Calculated number is multiplied in-flight by second power of IAS, cosine of Angle of Slip, Angle of attack multiplied by sort of polynom given by airfoil, and wing area.
    So, to increase glide ratio(and thus decrease drag) you need
    minimal wing chord,
    maximal aspect ratio, (at some point it will start to flap it's wings)
    Symmetric airfoil,
    minimal angle of slip,
    angle of attack between 0 and 3 deegres.

    @trios21 https://en.wikipedia.org/wiki/Sears%E2%80%93Haack_body ,
    and some knowledge about SP wing physics.

    how did you get so little drag

    @redcrafter idk then. Gears have drag and weight, but it still must be able to fly.

    fuck that i added some 1 2 i cant even get in the air like yall can

    @redcrafter If it's because of landing gears you can start in air.
