There are several Arplast propellers flying in the US and Canada. One 
that I sold to a Canadian customer for his 914 Tri-gear for instance. I 
think he's done quite a few hours now. We don't use the Colomban blades 
on the 914 but our wide hi twist blades. They have a 130 mm chord and 
more twist than the standard blade. This compliments the higher speed, 
higher hp and larger reduction ratios used on the Rotax 912S and 914. By 
all means contact me direct off the user group if you are contimplating 
buying a PV50 and want more information.

  Checking the Touchdown website,  The Arplast PV50 comes in two models 
- the Standard, for 1625 pounds sterling, and the Colomban, for aircraft 
capable of greater than 150 MPH (i.e., the 914 Europa XS), for 2050 
pounds sterling.  $2350, $2950 respectively.  Admittedly, cheaper.
  Electrically controlled, like the Airmaster.  Much lighter.

  Are there any Arplast PV50s flying stateside?

    At 2850$ it sounds a bit expensive? The Arplast is only 2320$ 
including blades. Can also offer feathering (but not in the UK due to 
regulation). Weight including blades is 9.2 kgs genuine (20 lbs). Around 
25 props operating on Europas already. Different blades for the 912 and 
912S/914. Also includes a digital pitch indicator.

      John Cliff informed me that my posts on Proplink bounced, so I 
shall reconstitute my post from memory:
      
      Proplink is a very new company that showed a new mechanical VP 
prop hub at Oshkosh 2000.
      (thanks to the poster who - now nameless - first mentioned this on 
this BB).  I e-mailed Brad Dement of Proplink after perusing their 
website at
          http://proplink.org
      This hub is a purely mechanical VP design that accepts either 
Powerfin or Warp Drive blades and is designed for a Rotax 914 at max.  
The prop pitch is directly controlled by a lever on the throttle 
quadrant.  The design allows for full feathering, although the standard 
quadrant limits blade angle to normal CS.  A feathering quadrant is 
being considered by the mfr.  The hub is a three-blade design, with a 
two-blade in the works.  The 3-blade hub weighs 13lbs, for an all-up 
weight including blades of between 18-20 lbs depending on supplier.  A 
weight reduction program is being followed.  The cost of the hub is 
$2850.
      
      This is an interesting alternative for Europa builders who want a 
variable pitch prop, especially motorglider builders who need a 
feathering prop, but would prefer a lighter installation than the MT 
(37?lbs) or the Airmaster (28lbs) and are willing to give up a CS mode.
      
      For those who need only a CS prop, the Whirlwind still stacks up 
as the lightest available, at appx. 12 lbs all up including hydraulic 
governor.  It is only a two blade design.  Indeed, if Whirlwind were to 
ever offer a 3-blade design, it would still be the lightest...
      
      The Proplink's $1100 price advantage over the Airmaster, and $1500 
advantage over the Whirlwind, should be noted.
      
      For your consideration...
