What was the problem over 150 mph? What are you using now?
Ref the IVO prop, can you give an opinion on reliability, operation and any problems or worries. I would like to fit one to my Europa for speed range 70 to 180 mph, probably on a 13b, if the RB Aluminum Hsgs work out.

I flew the Ivo Magnum (high pitch version) for awhile on my -4 (ground adjustable only) and tested it at near max pitch (~100").    Takeoff & climb was OK even though static & climb RPM was limited to only ~4000 rpm.   Flight performance will vary greatly based on the aircraft & power to weight ratio.  The -4 is an overpowered hot rod compared to factory planes.  The same setup on a Cessna 172 might be marginal at best.  Over all, the Ivo was great below 150 mph.  Above that it sucked.  Pusher installations seem to have better results with it (because it blows? : > ) sorry...

Folks,

I had a question concerning the electrically adjustable Ivo, If I 
forget to go to fine pitch when landing, what kind of performance can 
I expect if I need to do a go around? Just being cautious and wanting 
to know beforehand. Is there anyone willing to own up to having done 
it already? I'm going to be running a 180 hp 13b in a Cozy MK IV.

Bob
