Airfoil for Built-up RC plane wing

The flat bottom airfoil for my canard search and rescue radio control plane. Designed for moderate drag with a high lift incentive. 21 cm long with a 2.5cm thickness made for 1mm carbon rod for bracing and an 85mm carbon fiber square tube main spar.

Recommended to be cut out of wood, however for the sake of prototyping the .stl file has a thickness of 4mm and takes around 20mins to print depending on printer capabilities.
