Thanks Jon.

I will need those with 10mm shaft hole though. Motor max power is around 4000+ watts (5.8 hp) so hoping to get 12lbs of thrust. I am away now till late Saturday night and then back hopefully for some slope soaring on Sunday at Win Green.
I will let you know when we are likely to meet again. I will post up shortly what the prop is for. Waiting on HK for 10 SWG silicon cable
