Apparatus for superimposing numerical information on the field of view of binoculars and applicable in the flying of radio-controlled model airplanes is described. Airspeed and angle of attack are sensed by sensors attached to the model airplane, telemetered to ground, and converted to numerical form. An optical system is used to display the numerical information in the field of view of the binoculars used to track the model airplane. The numerical information is focused at infinity by collimating lens enabling the user to see the object and numerical information without refocussing his eyes.
