Calibrating Device for Measuring and Calibrating the Center of Gravity of a Remote Control Aircraft or an Airfoil Thereof

A calibrating device for measuring and calibrating a center of gravity of a remote control aircraft or an airfoil thereof, comprising:

• a crossbar arranged along a longitudinal axis and comprising a longitudinal rail and a slider movably engaged with the longitudinal rail, wherein the longitudinal rail is arranged in an extending direction of the crossbar, wherein the crossbar further comprises a drive member coupled with the longitudinal rail or the slider and driving the slider to move along the longitudinal rail, and wherein the slider comprises a pointer;
• a first support comprising a seat, two receiving portions and an auxiliary support, wherein the two receiving portions are arranged on the seat and are movable along a transverse axis perpendicular to the longitudinal axis, wherein the two receiving portions are aligned with each other along the transverse axis, wherein each of the two receiving portions comprises a load cell, and wherein the auxiliary support is detachably arranged on the two receiving portions;
• a second support comprising a base and a supporting portion arranged on the base, wherein the supporting portion comprises a load cell;
• and
• a control unit electrically coupled with the drive member of the crossbar, the two load cells of the first support, and the load cell of the second support.
