In the 11-13" diameter range what manufacturer makes the faster or fastest props? Have run the "run of the mill" APC and MAS props and most of the common wood props already. Any suggestions?
It depends. Which engine are you using? What kind of plane is it used on? What fuel are you burning? Lots of other factors. If you are looking for the highest static thrust for a given RPM, you will probably find that the APC gives about the best numbers at max power in the size range that you asked about. If you fall outside the numbers for max RPM, you may find that another prop design (wider blade) may give a higher number. It would help if we knew a little more about what you were trying to accomplish. I'm in Leesburg, so we can get together and try to figure out what you wish to do.
