Abstract
The model airplane control surface position measurement system and method uses an adjustable ruler scale attached to a support stand in combination with a laser device attached to the trailing edge of a control surface of the model airplane. The laser device may be adjusted to orient the light beam axis to be approximately perpendicular to the control surface hinge axis. The ruler scale may be positioned behind the control surface at a distance from the hinge axis using a positioning rod. The support stand is adjusted to orient the positioning rod perpendicular to the ruler scale at a zero angle deflection mark. The ruler scale is also adjusted such that the laser device light beam is incident at the zero angle deflection mark. The model airplane control surface may then be deflected by the control mechanism and the deflection angle observed on the ruler scale at the point of incidence of the laser device light beam.
