Fleery - as it was your statement on aerofoil sections used in trainers (I assume we're only discussing SE a/c) which prompted my response I'm obliged to pursue this point to the bitter end. From memory:
The Warriors use a 6 series section, as do the the odd Tomahawk, Grumman and Cardinal.
AMDT: there's the GAW-1 in the above list - developed by NASA from knowledge of supercritical sections, it promised fantastic CLMAX and low drag but the designers of little aeroplanes didn't read the fine print - at low Reynolds Numbers its worse than a 23015.
Sections on the aircraft below are not related to the 6 series at all.
Cessnas use a 23 series. The Airtourer at Civil has a 4412/23012. Decathlons have a 1412.
If we count the Pitts as a trainer its got one wing as a 6 series and the other a 4 digit series.
