70 CLASS F3A STUNTPLANE

OSMOSE 70


No.11854   ARF Kit

□Available : 14 Jun 2008

Latest stunt plane of designed by the 4-time consecutive World Championship winning Paysant-Le Roux is now recreated in 70-class.
Pre-assembled airplane matches the F3A performance of the full-sized version.
Friendly flat speed performance is ideal for intermediate fliers.

Four-time consecutive winner of the F3A World Championships, the world-renowned French champion Paysant-Le Roux's 2007 entry (2nd place) takes to the skies in a easy to manage 2-cycle 46-50 class or 4-cycle 52-70 class engine size. As a scaled down design of his original, naturally Le Roux was involved in ensuring that each section delivered performance over and above its size. The even shape and lightweight of the fuselage combines for easy-to-fly characteristics. The fuselage is pre-covered in high-quality film and given the Le Roux finishing touch with his unique color scheme. Intermediate to advanced fliers will be impressed with the authentic stunt airplane structure, and also the short time needed for completion. While complying with F3A rules, the design allows the fuel tank to be moved closer to the CG position when an engine with pump (sold separately) is loaded. For normal engines, the fuel tank can be positioned up against the bulk head providing a choice of specifications. In addition, higher flanks present a larger surface area for greater power on the knife edge. Also, based on testing by Le Roux, a ‘Canalizer' included as standard draws the airplane down a more consistent line. As the latest 70-class stunt flier designed specially for F3A competition, the OSMOSE takes stunt flying skill to the next level.

Le Roux designed stunt plane realized in 70-class. A scaled down version of the 2007 World Championship entry maintains the original's spirit and performance.

 

Lightweight design matches the performance of the full-size version but with a 2-cycle 46-50 or 4-cycle 52-70 class engine sizes.

 

Fuel tank can be positioned on the center of gravity when mounting engines with a pump. Changes to fuel tank volume have minimal impact on C of G for consistent flight characteristics from takeoff to touch down.

Rudder and elevator servo loaded through a hatch on the bottom of rear fuselage. Excellent for linkage adjustment and maintenance.

 

Aerodynamic design of included two-piece main gear and wheel covers minimizes wind resistance. Limits the excess effect of wind for smoother, more responsive control.

 

Designed by 4-time consecutive F3A World Champion: Christophe Paysant-Le Roux. The skill of the World Champion designer condensed into 70-size.

Surface area, shape and angle of ‘canalizer' are typical of Le Roux's unique design skills. Draws the airplane down a straighter and more consistent line.

 

 

  • 2007 World Championship entry OSMOSE has been realized in a 70-class version.
  • Form and dimensions comply with the latest F3A rules.
  • Almost completely factory-assembled in lightweight balsa. Complete with Le Roux's unique colorful graphics.
  • Rounded shape of the tapered Duralumin main gear reduces wind resistance.
  • Fuel tank positioned as close as possible to the C of G so changes in fuel volume have minimal effect on the C of G position.
  • Fuel tank can be positioned directly behind the bulk head when mounting engine's without a pump.
  • Includes linkage parts expected of stunt airplanes such as push-pull wire linkages.
  • Tail gear unit delivers reliable taxiing and protects the rudder from direct shocks.
