I might have created a foil that makes sense ?!

I kept modifying FX73 and FX 75 separately and then combined them.
CL max is 1.7
Tad thicker..
This has lift 1.716 Cl MAX
The foils won't work in re 200000 area...for the R/C model so this fx73 blended with hq3510 and Aguilar seems to work;
If you doubt my ability to switch foil into other re-area..then here ios my present to the aircombat hobbyist..my vision for the 1/12 scale P-51D as 10% ( thinnest the rules allow ). Its re 200000 Dd is 0.011.
Some of the Cl/Cd_alpha figures as a chart;
