Currently running a 70in Whirlwind ground adjustable on my 912is. Overall I'm very happy with the performance. I tend to run it slightly favoring climb performance.

I've been considering upgrading to the airmaster, my main goal is squeezing a bit of cruise performance out of it (I currently get about 104 mph, 5500 RPM, grove gear, 26's). However I do not want to give up any of my take off performance, and it would be great to gain a bit of course!

In flight adjustable seems like an obvious choice and I would like the groups opinions.

That said, I've also been told there may be other props/diameters out there that would improve my performance on both ends over the whirlwind, without the complexity of an in-flight adjustable. Would love thought here too.

Considering all options/opinions!
