Paul,
 Have you seen the Aerocomposites cs units?
 http://www.aerocomposites.com/or
 the MT, or Hoffman, for weight.....all are composite blade, oil fed
 constant
 speed units. Lighter weights. I've heard good reports from aerobatic (and
 seaplane) pilots running some of them, esp the aerocomposite ones.

 MT and Hoffman have electric versions as well.

 Paul, others.

 I have heard good things about Aero Composites but they are unwilling to
 make a electric version.
 This begs the question.   Are electric C/S props  adequate for non
 acrobatic flying?  If so it seems a shame to add the weight and
 complexity of a belt driven prop governor, plus the hassles of the
 hollow prop, shaft seals and  hoses etc.

 Mark Steitle runs one so lets ask him. Mark how well does it work?

 Paul,

 Bobby Hughes and I are both running 3-blade M/T electric props and we're
 both very happy with it.  I get great takeoff & climb performance (6800 -
 7200 rpm) and once at a safe altitude, I can dial it back for a more
 economical cruise climb (6000 rpm), and finally to economy cruise
 (5100-5200
 engine rpm).  The best feature is that I can change the prop pitch in
 flight
 if I want go fast.

 Not having an adjustable prop would be like riding a centrifugal clutch
 Cushman motor scooter, if you remember what those were like.

Mark,

Is you prop constant speed or electric in flight adjustable ? Are you
flying
WOT all the time and regulating rpm with pitch ? This is how we flew a
Glastar with an electric NSI prop.

John,
It is a constant speed.  But it will allow you to switch and fly in MANUAL
mode if needed.  I don't fly aerobatics, but I don't think this prop would
work well for that as it takes longer to adjust than a hydraulic prop.  But
that isn't a problem in the type of flying I do.
