There was an excellent article in the last issue of Kitplanes about Jeff
Ackland's Legend which now has installed a Walter M-601 turboprop with a
beta-capable Hamilton-Standard propeller.  Chuck Berthe wrote the article
and mentioned Jeff's use of flat pitch to restrict the idle-thrust float
which would be induced during landing and also made some mention of using
beta during ground operations.  I'd highly recommend reading the article if
you haven't already.  You might also think about talking to Jeff and asking
him about his testing results when he began his experiments with the beta
abilities of his installation, as while the Legend is only a 2-seater, it's
certainly one of the few experimental aircraft out there which has
performance capabilities up to those of the Lancair IV, and things which he
learned could well apply to your proposed installation.  If you do manage
to contact him, be sure to let us know what comes of your conversations.
