Canadian Manufacturer Updates Composite Kitplane Design
By ANN Correspondent Juan Jimenez
Partenair Design Inc., a Montreal-based kitplane manufacturer,
introduced the Mystere Mark II today at Sun-N-Fun 2003. The Mark II
is an update of the original Mystere Mark I, a sleek, fighter-like
low-wing homebuilt composite aircraft with tandem seating for two
and a pusher engine configuration.

Externally, the aircraft's looks have not changed, but company
officials told ANN that they have made the following changes.
The engine installation has been modified by raising it four
inches higher than on the Mark I design. This allows the Mark II to
use a 70 inch prop versus the 61 inch maximum propeller diameter on
the Mark I. This new propeller configuration improves takeoff
performance and results in an additional 8 mph increase in cruise
airspeed. In keeping with most pusher propeller configurations, the
designer continues to recommend only wood or composite props for
the aircraft.
The engine cowl has been modified with the addition of NACA
scoops at the top for improved engine cooling. The propeller
installation also helps to draw air through the cowling to further
improve the flow over the cylinders.

The company also reports that they have five customer aircraft
under construction - one in Italy and four in Montreal, at the
company's customer assistance center. The kit price remains at
$27,500. There is a fast build option available for an additional
$6,000, but at press time the company is offering free fast build
options to the next five customers to purchase kits. The customer
assistance center, located in Montreal, is meant to help the
customer get up to speed in the skills needed to complete the
aircraft, and is estimated to cut some 300 hours or so off the
total estimated build time of 1,500 hours.
The kit price does not include engine, instrumentation,
upholstery or paint, but it does include all the jigs for
construction of the aircraft. In fact, the boxes for shipment of
the kit parts are the jigs! This clever feature helps the builder
to correctly set up and complete the aircraft components without
having to build, rent or beg for borrowed jigs.
