Default RE: NACA numbering scheme
Other than a general confirmation of the type of airfoil, with no explanation as to what's different about it, I found this on a Bulgarian site..

I'd use a 2414 myself.
..
Looked in Profili.... presuming the "R" is some "revised" designator for an NACA 2114, and plotted a 2414 on top... I got this.
Not enough difference to be concerned about for model size.
