David:

You are using the high pitch IVO blades I presume (I've read they have= a "+" on the hub. Is your set up for fixed pitch or in-flight adjust= able?

If In-flight adjustable, did you hook up an amp meter to your prop con= trol toggle switch circuit so you can get an idea of the amount of pitch yo= u have set in?

On take-off with the Subie, do you have to keep adding pitch on rollou= t to keep the engine from over-speeding?

Thanks for any info...I also will be flying behind an IVO (someday) so= am curious what others are finding out about using them on RV's. Ros= s Farnham's SDS site has a lot of good information on his use of the IVO on= his Turbo Subie 6A...

Blue skies,

Doug
