The Parker Jeanie's Teenie, or JT-1, is a single-seat, single-engine sport aircraft first built in the United States in 1967 and marketed for homebuilding.
"[2] The cost of materials has increased since the article's publication but the initial popularity of Parker's Jeanie's Teenie was high.
An engineering study produced the requirements for a safe minimal design that Parker then doubled to ensure durability.
[2] Jeanie's Teenie was conceived as an airplane that could be built using only hand tools that would be possessed by the average person in the late 1960s.
The landing gear is a fixed tricycle configuration with nose wheel steering through rudder bar deflection.
This makes ingress/egress of the tight cockpit simpler and prevents leg movements from imparting motion to the stick inflight.
Very little welding is required, and is generally limited to the landing gear, motor mounts, and small control linkages.
[citation needed] The flight characteristics of the design were intended to be quick but not oversensitive, for mild aerobatics and handling in rough air.
With a fuel capacity of seven gallons and a typical cruise power setting, the Jeanie's Teenie has an endurance of nearly three hours.
As the plane was intended for simple, cheap VFR flying, builders should resist the urge to install extraneous equipment or features that would increase the weight of the vehicle.
