Aircraft wing showing the KFm2 Step Aircraft wing showing the KFm3 Step. The Kline–Fogleman airfoil or KF airfoil is a simple airfoil design with single or multiple steps along the length of the wing. The purpose of the step, it is claimed, is to allow some of the displaced air to fall into a pocket behind the step and become part of the ...

Early versions merely constrained the model to fly in a circle but offered no control. This is known as round-the-pole flying.The origins of control-line flight are obscure, but the first person to use a recognizable system that manipulated the control surfaces on the model is generally considered to be Oba St. Clair, in June 1936, near Gresham, Oregon.

The position of all three axes, with the right-hand rule for describing the angle of its rotations. An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.

F1B Model by Stepan Stepanchuk. Free flight is the segment of model aviation involving aircraft with no active external control after launch. Free flight is the original form of hobby aeromodeling, with the competitive objective being to build and launch a self controlling aircraft that will consistently achieve the longest flight duration over multiple competition rounds, within various class ...
The Kitfox Model 4 was a new design introduced in 1991. It incorporated a laminar flow airfoil, new flaperon design, metal flaperon attach brackets and a new 2:1 differential aileron control system. The gross weight of the Kitfox Model 4-1050 was the same as the Model 3, 1,050 lb (476 kg).
