Yeah i was wondering about that too.Sometimes if you hear that 'rubbing' noise in flight it might be bearings.Rowdog lightly grip the prop tips and rock the prop back and forth,can you feel or hear any movement?

Barry if i remember right you fitted a steel backplate to you 72 because it was sucking air at the upper intake tube where it meets the head? the three 82's i have with the plastic backplate have given no trouble over the years tuning wise one of them has a couple of hundred hours flight time.

popo imagine you are all tucked up in bed and the fairy godmother is perched on the bedside reading you a goodnight story while waving her magic wand..a girlfriend has found me a flouro pink half see through skimpy tu tu dress to wear on 'any sunday' (i'm not allowed to wear any undergarments) while carving up those slow harley riders in the hills.She says it may give them all a sudden attack of limp ***** syndrome but i'm not sure what that means.
