The newer Radial A Pack motor came with a nice spinner nut and a short motor shaft. I bought a bunch of HQ 6x4.6 props, but they are all too thick with about a 9 mm hub, so the nut barely threads onto the shaft. Are APC 6x3 props thinner at the hub? I happen to have some triblade Gemfan 6045BN which have 7.5 mm hub to fit the A radial motor now, but what 2 blade props are suppose to fit this motor? Can the hub be safely "milled" down fit the motor? Application will be Mighty Minis and the Commuter.
