It will turn a love of flying into a passion for flight. Once in the bi-plane cockpit, you can’t wait to get intothe air. Cruise speed is an invigorating 70 mph, with exceptional stability for hands-off flight capability.

Construction of the FP-404

These bi-planes are available either as a complete kit—which contains everything you need except instruments, paint, varnish and pilot restraint system—or in “pay as you build” partial kits. Aircraft-quality materials are supplied throughout; you simply epoxy the wooden pieces together over the full-size plans.

After the woodwork is completed, it is sealed with polyurethane varnish, covered with heat-shrinkable aircraft fabric, sealed and painted to provide a long-lasting durable airframe.

The average builder can assemble a FP-404 in 500 hours using normal household tools.

Airborne Adventure

The FP-404 represents a reborn era in airborne adventure. This bi-plane aircraft is a throw-back to seat-of-the-pants flying, complete with minimal instruments and bare-necessity controls. The sports car of light-planes, the FP-404 is a flying experience that will leave you flying.

Featuring short wings, full-span ailerons and a semisymmetrical airfoil, the aircraft answers commands instantaneously. Geodetic wood construction and additional bracing contribute to exceptional structural strength, enough to withstand higher Gs than most lightplanes.

For experimental models, a 50 horsepower Rotax engine pours out more than enough power for exhilarating, 800 feet-per-minute climbs and turns that will push you back in your seat. The plane is as responsive as you are aggressive.
