Digital CG Scale V3

A precision digital tuning tool, now with more versatility!

Whether you fly in competitions or are just plain fascinated and exacting with your aircraft tuning, a digital CG scale might be just the tool you are looking for. 

Now featuring new innovations such as adjustable leading edge pegs. This allows the scale to measure a center of gravity all the way down just 15mm from leading edge, great for thin high aspect ratio wings and plank ships. 

The Digital CG Scale V3 also features a much wider yoke, allowing the unit to accept fuselage widths, up to 106mm in diameter and an extendable tail support allowing for even more aircraft types. 

It works like this.

With the plane setting level in the yokes, and the wings leading edge touching the now adjustable vertical pins, the scale weighs the aircraft and calculates the CG similar to the way the CG is calculated for a full scale plane. The LCD display shows both, the all up weight of the aircraft as well as the center of gravity in millimeters from the wing's leading edge. The relatively high capacity of these scales allows you measure your aircraft with the ballast on board. This makes ballast adjustments and CG tuning a snap.

Construction. 

At the heart of the scale are two highly sensitive, bending beam load cells. The load cells are connected to an Arduino CPU and the scales frame and yokes are 3d printed.

The cradles are 4" wide (between the pads) by 4.5" inches deep.

The scales are shipped calibrated and ready to use.
