So I got a 2013 Z3 with the 409 and smashed my prop this weekend. I ended up buying a spare Acme 1589 (only fitting prop they had) which is less than desirable, but the top end I gained from the 2419 it had installed was impressive. While at the shop (Liberty in Lake Havasu) they mentioned they started carrying Powertech props because they are just as good as Acme but a fair bit cheaper. I’m writing this post asking if anyone has tried a Powertech and if so, would you buy one as a replacement. I wanted to try a 1235 but am also looking for other recommendations. I stay at low altitudes normally, under 2000’ and am upgrading to have about 2,000+ lbs ballast. Any input would be appreciated.
