I dropped the prop back to them on Thursday am and Thursday pm they couriered it back to me all done and correct this time 25mm out of the short section of rear prop and 19 CM out of the long rear section.
Oddly enough my oppliger gear kit came with a 25mm spacer for the front prop but I already had a complete new prop made to suit anyway.
I have the really strong reyland uprated cover and the clutch is super light, really pleased with that.
