Just stick a semi-symmetrical airfoil on it with, thinner at the tips (for the scale look) with flaps and a bit of washout on the tips.
And just learn how to fly it. The wing will always do its best, the pilot is the big variable.
Drilling down to the point--learn how to land it properly using full size airplane techniques adapted to the particular airplane/ flying field.
There is precious little info out there on how any of the commonly used airfoils will act when scaled down to the Re numbers that .60 size models fly at on landing.
So unless you can find hard wind tunnel info (from a reputable wind tunnel--and you won't-- current fully characterized wind tunnels consider operating Re numbers lower than about 10 million as beneath their dignity) on airfoils in the 100,000 Re range there is no point in trying to get overly technical on powered model wing design.
You have nothing to base anything on. But if it makes you feel better tho, go for it.
If you're an average to below average pilot, you'll foul up the landing approach sooner or later, and re-kit it, super trick airfoil or not.
Just my 2 bits.
