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 adjustable? 

 

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

 

On take-off with the Subie, do you have to keep adding pitch on rollout 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.  Ross Farnham's SDS site has a lot of good information on his use of the IVO on his Turbo Subie 6A...

 

Blue skies,
