Curtiss Jenny Kit # SIGRC93ARF Assembly Instructions America’s Most Famous World War I Airplane ... The Curtiss Jenny originated in 1914 in response to the U.S. Army’s desire for a “modern” trainer, an airplane with an enclosed fuselage with the engine mounted on the front. Prior to the Jenny, the Army had been flying primarily open-to-the-wind pusher airplanes, and their accident fatality record was gruesome.

Chargers: If your transmitter has rechargeable batteries, use the charger that is supplied or recommended by the manufacturer. This is usually a slow charger (overnight). Although there will be some variation from transmitter to transmitter, the average fully charged transmitter battery will provide around two hours of operation.
4...Use 5-minute epoxy to glue the plywood Firewall, (4) Cowl Mounts, Servo Tray, Tailskid, and aluminum Wing Tubes in place in the fuselage. Firewall & Cowl Mounts Servo Tray Be sure the firewall is seated snugly into the recess molded in the front of the fuselage. This provides built-in down and right thrust to the motor. Glue the servo tray in with the grain running across the fuselage. The wing tubes should stick out an equal amount on each side of the fuselage. Tail Skid Wing Tubes 5...
To apply the decals, leave the clear plastic in position while you cut the individual marking from the main sheet. Then remove the clear plastic and place the decal on the model in the desired position, adhesive side down. Make sure you get the decal exactly where you want it. The light tack adhesive allows the decal to be picked up and repositioned if necessary. With the decal in the proper position, use a brush to generously apply cold tap water to the paper.
To operate the system, first turn the transmitter on and place the throttle stick in the low position. Now plug the airborne battery into the input side of the electronic speed control and the system is operational (see NOTICE: below). Test the system by moving the right stick on the transmitter, which should move the rudder and elevator servos. Initially, the motor is not armed and will not function when you move the throttle stick.
16...Finally, plug the servos and electronic speed control into the receiver. Place the receiver in the fuselage beneath the servos. The electronic speed controller sits on the bottom of the fuselage in the battery compartment, between the servos and the firewall. Plug the battery into the system and check the radio for proper operation. If the servos move in the wrong direction, use the servo reversing switches on your transmitter to change the direction of travel.
