On a serious note, how are people taking care of a constant speed prop
through the PSRUs that they are using?  It seems to me that the 13B
will be happiest at about 4500-5000 RPM all the time, and a constant
speed prop would be a good way to get there.  Not to mention that a
Cozy has a rather long ground roll without it.

Well mostly they are not. Some are fooling around with the IVO
electric prop. I am thinking of going with a German MT or Hoffman
or one from NZ called an Airmaster. All are electric.

I guess I need to put two cents in here.  You didn't mention Marcotte.   If
the PRSU is already purchased(please excuse my ignorance) the Marcotte has
the ability to use Hydrolic props and there is a governor which mounts on the
V belt.[???]  If the PRSU is already purchased, its a mute discussion.  Sorry to
waist your time. Jim

Opps, I forgot Jim and the Marcotte here. Sorry Jim.
