RE: Picco P-zero 0.8cc
Graham,
I've also seen that APC info - about the centered hole being in the rear of the prop.
What does not make sence is that the reducer they send you only fits in the front - making the front hole primary?
I use the front hole if using a spacer (small props), and use the rear hole if reaming the prop,
Not to infer that I am a back door man...
