| - The ParkZone™ J-3 Cub is a ready-to-fly, scale R/C electric park flyer-sized airplane distributed by ParkZone, a division of Horizon Hobby of Champaign, Illinois, USA. A slightly different version is sold under the Kyosho brand. The J-3 is constructed of foam with a polymer outer skin. The fuselage consists of two thinly molded halves with an internal framework of plastic. The wing and control surfaces are polymer with a foam core. Control surfaces are limited to elevator and rudder; the model steers via rudder alone. Steel pushrods with adjustable plastic clevises activate the control surfaces. ParkZone's "SmartTrak" software mixes a slight amount of up elevator with rudder input. Experienced pilots can easily disable the system with the removal of a small jumper on the onboard electronics system. Propulsion is via a geared 370 electric motor with a seven-cell, 600mAh nickel metal hydride battery pack. The Kyosho version utilizes a 280 motor in the same basic gearbox. Electronics are ParkZone's proprietary 27 MHz three-channel proportional FM system. Servos are standard micro-sized; it is possible to install off-the-shelf discrete electronics in the J-3. The Kyosho uses a standard discrete four-channel system. Both the ParkZone and Kyosho versions are sold as complete, ready-to-fly packages which include a DC peak battery charger designed to plug into an automotive cigarette lighter socket. ParkZone includes eight heavy-duty AA batteries for the transmitter while Kyosho provides an instructional video. Cruising speed is rated at 20 mph/32 kph.
