Thank you for confirming this.

I have found a calulator on RCGroups from May 2005 which generates a
Simplex airfoil from Chord and % camber so I can get the 2 or 3
different templates for a mixed F1L or EZB wing. I opened the *.txt
file in the post listed below with Excel and was able to get tables of X
and Y for airfoils. I used the Graphing function of Excel to plot them,
after adjusting the axes of the graph to give a 1/1 printout. It might
be better to divide metric chords by 25, or perhaps change the step size
in the function, to make the calculator more friendly to chords in mm.
iIt takes a little trial and error to match the height of straight and
diagonal ribs by adjusting the % camber.

Hope you and others find this useful.
