Who makes this gearbox, and how much does this baby weigh? Does it have
its own oil reservoir? I understand this set up is what the Marcotte
unit needs as well.......

The gearbox on the Eagle540 has its own oil pump / filter / cooler and
the 
[McCauley] prop governor is mounted directly to it. It uses its own oil
supply 
(designed for gears instead of engines) to spray-lubricate the gears and
its 
pump provides clean, cooled oil to the prop governor for its final
pressure 
boost.  One nice thing about having a closed lubrication system for the 
gearbox is that you can use oil which is optimized for that purpose, and

tracking its separate oil pressure and temperature provides some warm
fuzzies 
re the condition of the gear box.  Just thought I'd share the data
point.

  Hi Ed,
  No, this will utilize the typical oil driven type cs prop governors
  found on 99% of aircraft now. It will be fed and will supply oil to
the
  prop hub just like most typical cs props-just like Mistral's unit and
  the Marcotte unit (but much more economical, if we can pull it off). I
  want to use a Whirlwind type prop-they use Hartzell type cs hubs. It
  will have a typical SAE cs type prop flange. Use any cs prop. It is
  based on a planetary reduction in production for other uses
  (helicopters) in Eastern Europe.
