====Aerofoils====
Wing profile sections in models vary, depending on type:
* Origami : Göttingen flat-plate, or Jedelsky-form for folded leading edges.
* Compound Origami: Identical with origami, though often with sealed edges – 45% improvement in Cd.
* Profile Performance: Göttingen curved-plate, with profile similar to Göttingen 801.
* Scale Performance: Göttingen 801 or any other wing aerofoil
* Scale Models: This varies on model type (see below)

[[Camber (aerodynamics)|Camber]] of profiles varies, too. In general, the lower the Re, the greater the camber. Origami types will have 'ludicrous' or very high cambers in comparison with more marginally performing scale types, whose escalating masses demand higher flying speeds and so lower induced drag from high camber, though this will vary depending on type being modelled.

In the case of scale performance and scale models, the modellers intent will define the type of aerofoil section chosen. WWI biplanes, if designed for flight performance, will often have curved-plate aerofoils, as these produce a highly cambered surfaces and Coefficient of Lift (Cl) for low gliding airspeeds. WWII monoplanes will often have very scale-like sections, though with increased trailing edge droop to improve camber in comparison with scale counterparts.

Similarly, size, airspeed and mass will have very big impacts on choice of aerofoil, though this is a universal consideration in model plane design, no matter the material.
