Performance Features

  • The "center line thrust" Golden Butterfly trainer is a POWERFUL two-place tandem gyroplane. This exciting HUGE flying machine has been thoroughly tested and has exceeded our expectations.
  • Climb out with a 200 lb. pilot is a whopping 1,500 ft./minute and with two 200 lb. people it still climbs at 800 ft./per minute.
  • By removing one bolt the mast can be folded from 11' high to 7'10". The same bolt can be used to give 4 different pilot Center Of Gravity setting for a 150 lb., 200 lb., 250 lb., or a 300 lb. pilot with superb handling qualities.
  • With a 300 lb. pilot The Golden Butterfly still climes out at an amazing 900 ft./minute. What a ride.
  • The patented G-Force Landing Gear is a needed safety device when the student flares too high. This unique long stroke shock mounted parallelogram landing gear is a break through in gyroplane safety.
  • The mast has a unique shock absorption and spring loaded dampening system that has removed most of the vibration out of the airframe. There is practically no stick shake due to isolation dampeners in the push pull tubes.
  • The Subaru 2.5 engine with a cam grind puts out a whopping 190 HP and drives a huge 76" 3 blade propeller.
  • The Stratomaster glass cockpit display which includes a rotor tachometer is a high tech wonder installed in the instrument panel.
  • The huge all flying 60" tall tail with a 50" wide horizontal stabilizer that centers the propeller blast is a powerful true airfoil combination that gives The Golden Butterfly powerful yaw control to easily overcome a large crosswind component.
  • The instructor in the rear seat also has an instrument panel with airspeed and altitude gauges included.
  • The Golden Butterfly is specifically designed to train students how to fly The Butterfly and Monarch gyroplanes but can also be used for a thousand other tasks, one of which is just pure fun flying in a huge, open frame, gyroplane with a friend.
  • Set up with a climb prop the top speed is 95 mph with a fuel capacity of 15 gallons.

 

Materials

  • The airframe materials kit has pre drilled locator holes that will have to be re drilled to size and some of the tubes will have to be cut to length.
  • The kit is intended for the experimental category where you as the builder fabricate at least 51% of the kit for recreation and education.
  • The cheek plates and various other parts are cut to shape and have undersized locator holes.
  • The front landing gear, landing gear support, joystick, and rotor head washer are made from 4130 Chrome Molly steel and they are heat-treated. All the parts are either powder coated or anodized in this kit.
  • The tail is made using Kevlar.
  • We strive to keep the integrity of the true Amateur Built aircraft kit.

 

NOTE: We are only selling complete experimental aircraft kits, not parts. Each part was designed exclusively for the Golden Butterfly. Use of The Golden Butterfly's parts on any other vehicle is strongly discouraged.

NOTE: The undersized locator holes are pre-drilled for easy location and assembly. The Golden Butterfly can easily be fabricated and assembled using common tools: Vise, drill press, belt sander, cutoff saw, SAE tools, etc.

WARNING: The Golden Butterfly may be as dangerous as any other aircraft and could cause injury or death. Build or fly one at your own risk.
