Something to keep in mind with the APC's is that the electric props use the larger REAR portion of the hole to locate the prop, and you absolutely HAVE to sand the rear of the hub if uyou are going to spin the bejeezus out of them. The mold flashing makes then run out of true and mimicks an out of balance vibration.
Actually, if you have a look at APC's website you will find that they specify that the larger rear hole is the one that is centered, not the smaller front hole.

Yep, that's what Isaid.
ETA:The spacers fit the rear. If you guys are getting them in the front somehow, I'm curious to know how unless you have an arbor press.
