Managed to escape from my test laboratory. The following airfoils were never intended for publication, but somehow The following four airfoils were published to improve the maximum lift coefficient compared to available, low c m.to cause only small torsion coefficients c m c/4, and.to achieve low drag values comparable to typical airfoils used on F3B.

The main aims during the design of the MH 40 series and MH 60 series airfoils The winch, which often resulted in a complete disaster.

A typical, asymmetric wing stall lead to a complete loss ofĬontrol, resulting in a high speed corkscrew flight path under the full power of The altitude, which is achieved during the high start phase of the flight, isĮxtremely important, the tailless models suffered badly from these airfoilĬharacteristics. Lift coefficient and an abrupt stall characteristics of these airfoils. This was caused by a rather small maximum Performance of these models was quite good, the high start performance and In the late 1980s, when the LOGO-team approached me with the wish for newĪirfoils, various airfoils were used for tailless F3B model planes. More details can be found in the links below. Sweep and twist usually cause a performance loss, whichĬan be minimized, by choosing airfoils with moment coefficients c mĬ/4 close to zero. Models, if their torsion moment is compensated by the appropriate combination of It is possible to use the sameĪirfoils which are used on high performance F3B The airfoil should be carefully selected. But if performance is an issue, as it is the case in contest flying, In principle, tailless model planes and flying wings can be equipped with anyĪirfoil.
