off the deep end i think i was gettting between 8100-8200 but i need to double check that figure for you. As this was the last prop i test and with the others ones i kept all these figures in my head as i usually write them all down..... Tipover that 18 x Mejzlik was night and day. I say this because sometimes a prop only does one or two things better than the next or sometimes it very very hard to see the difference. with this swap out it was very easy to see a difference......
