- Page 2 Features: The Xicoy CGMeter Basic allows both weight and balance of aero models of more than 50kg (110lb) weight, being limited by the maximum weight on a single scale of 25kg. Each scale is made from tempered & anodized aluminum and has a resolution of 1g.

Page 3: Electric Connections
Electric connections: Connect the Blue and Red sensors to the yellow main unit using the leads supplied each sensor in its own socket. Connect a battery between 5 and 10 volt on the battery socket as per picture. Connecting your terminal to the CGMeter: Inside the main unit there is a standard Wi-Fi server, like your home router. -
Page 4: Basic Operation
Basic operation: This instrument allows to do several measures, and to do so, it needs to know some data from your plane. Depending on your needs, some of the data is not necessary to be entered. We will describe step by step the measures that can be done, the data to be entered to do these measures and how to take these measures. - Page 5 If the plane you are balancing sits on the ground in nose up/ down attitude, then add some height under the sensors until the plane “looks” like it was flying. For extra accuracy you can measure the wing or tail incidence, but usually not necessary. To calculate where the CG currently is, the instrument needs to know the weight on each scale, plus the distance between the centers of the scales.
- Page 6 Now touch the “Data Entry” tab in the app. This will show a form to enter the data. First optionally you can enter the name of the model. Not necessary, but could help in to remember to what model belong the settings currently in use. Next you should choose the configuration of the landing gear.
- Page 7 Measure using the laser: Place the laser module close to the measuring tape, and move it until the line is centered to the mark of the CG. Annotate the measure (72mm on the picture. Measure using gravity: Don’t worry if you don’t own the laser module, using the gravity the measure is easy to do too.
- Page 8 Now check that the plane is sitting comfortably over the sensors, that is levelled and sensors had been zeroed recently, then scroll to the balance section on the CGMeter App. Now we see that the recently data we just entered (47mm) is displayed as “desired”...
- Page 9 Wet balance: All the measures in previous pages had been done with the fuel tank empty, as is normal practice for the manufacturers of model airplanes to define the recommended CG position with the plane “Dry”. The CGMeter allows showing the CG drift when the plane is fueled, but to have this information, we must feed it with the appropriate data.
- Page 10 Sensor calibration: The sensors come calibrated from factory, but can be easily recalibrated if needed. Procedure is simple, but you need a reference weight, recommended to be over 1 kg (2lb). To measure the exact weight of the plane is important that the sensors be calibrated with a good reference weight, but for to measure the CG it is important that all 3 sensors be calibrated with same reference.
