Next thing to consider is construction. I want simplicity and ease of repair / modification and the only aerofoil to use here is the KF (Kline–Fogleman) type that uses a series of steps in the basic form to create a rudimentary aerofoil shape. These are idea for small, light model aircraft as they word well and are extremely easy to make.
The shape I am opting for is a KFm-3, this type gives me a nice thick wing to play with with a decent shape. It is non symmetrical because I have no intention to do full aerobatics, but the lower section should help flow around the leading edge during pitch up.
Power will be from a centre 6" pushing propeller, and the control will be from 2x mixed elevons. These elevons will have a slight upward angle to provide a level of effective 'washout' to the wing. This is essential to maintain control of the wing in the event of a deep stall and on landing.
Because fine control is needed with a flying wing, a fair bit of reinforcement will be employed...
