WHAT 3-BLADE PROP EQUALS 15X8 2-BLADE?
How does one convert from a known two-blade size to a three-blade? If I wish to change from a 15X8(Master Airscrew black) two blade, what 3-blade size would I use? Will there be a performance loss/gain going from two to three blades? I'm interested in maintaining better performance in the higher speed range. The aplication is a Bruce Tharpe Engineering Delta Vortex using an OS 91 FX.
