Excalibur II Now in Production September 1998
The most noticeable difference between the Excalibur II and a Challenger is the pusher engine on the Excalibur is mounted upright, allowing the 52-hp Rotax 503 dual carb engine to use its own integral gearbox rather than an after-market belt drive added on. As a result, the extra boom tube clearance permitted by the upright engine allows the Excalibur to swing a larger propeller - a 66-inch wood prop from Tennessee Propellers. The Rotax B gearbox is standard, with either the C or E boxes as options.
The landing gear system is also different, using bungee shock cord main gear suspension. Manual main wheel brakes are standard, with Hegar-style aluminum wheels and tires.
A different and smaller fiberglass nose cone is used with a LexanŽ windshield (either tinted or clear), while the opposite end has a larger rudder surface.
Other features include: electric start, 10-gallon fuel tank, streamlined aluminum struts and military-type seat belts and shoulder harnesses.
Options include: 60-hp HKS 700E air-cooled 4-stroke, or Rotax 582, 65 hp, water cooled 2-stroke engine, instruments (ASI, altimeter, tach, dual CHT dual EGT, panel-mounted compass, ignition switch), standard or amphibious floats, fiberglass wheel pants, BRS ballstic emergency parachute, doors, strobe lights and paint materials.
Construction is 6061-T6 and 2024-T3 aluminum tube airframe with chromoly steel weldments where needed, stainless steel pop rivets and AN or military spec hardware. Wings and surfaces are covered with Superflite fabric. No welding or machining is necessary and all the critical work is completed at the factory.
The kit for the Excalibur II features prebuilt tail surfaces, wings, ailerons end fuselage, and all the controls are already installed. Build time for the kit is estimated at 150 to 200 hours.
