Hello group,
I purchased a Starlet with a 2 piece spar last year. I am entertaining the idea of up grading to a one piece for the gross weight increase for aerobatics. The original airfoil is NACA 43012A. From John Corby's notes the original Reynolds Numbers were very high (8x10^6 - 3.8x10^6) for this airplane and that why he choose this airfoil based on those numbers. 1.6x10^6 thru 3x10^6 would cover the speed range of the Starlet. I have came across another airfoil that might have better characteristics: NACA 23112/43012A Hybrid.
I have access to a CNC Router to build rib jigs, so I can very precisely profile an airfoil.
I have attached John Corby's notes for NACA 43012A.
Any information about the characteristics of NACA 23112/43012A Hybrid would be appreciated.
Thanks,
Atpandpa
