Abstract: A hand-held movable airplane or boat model is equipped on an outer face with gravity actuated simulations of actual navigational instruments. Two interchangeable compass rose discs are mounted each on a separate split shaft spindle protruding from the model. One disc is asymmetrically weighted to maintain the disc in one orientation while the model, held in a vertical plane, moves and rotates to simulate routes of travel. When used with an indicator on the front center of the model, the weighted disc simulates an azimuth directional gyro. One of the spindles is bored axially to admit an indicator shaft rotatably therethrough. An indicator arrow mounted orthogonally on the outer end of the shaft aligns with an orthogonal extension on the inner end of the shaft below the model.
