I have a pair of APC propellers arriving Wednesday from Horizon, they were supposed to be here tomorrow but were shipped from their California facility, so they will not make Monday. The .25" hole is going to be problematic as they need to be 7mm for the .66 FrankinSaito. I have a B&B reamer with a .25" pilot but it is 8mm. So, I'll have to fudge some way. Pictured is the 13 x 7 it will be accompanied by a 13 x 6.
Regular Sport propeller.
