The design of the frame makes it possible to balance motor models with landing gear or wing struts. The fence can be rotated by 180°. An additional pointer is used for this purpose, allowing the exact center of gravity to be set. The frame can be rotated so that it does not interfere.

The ball bearings make it very precise and durable. The rocker itself has stops and therefore has a maximum deflection of 10° in both directions. This means that the model can no longer fall off the rocker, even if the model's battery is removed, for example.

Furthermore, the wing stop has been arranged with a 10° inclination. When the rocker is in the front end position (10°) at the stop, the model can be placed. In the neutral position during weighing, the surface stop no longer interferes.

The engraved scale allows the center of gravity to be set with millimeter precision.

The wooden parts are CNC-milled from high-quality and stable 15 mm birch multiplex. The plug-in system makes the center of gravity scale even more stable and therefore easy to assemble.

The wooden parts are covered with self-adhesive rubber at the contact points so that the model is held securely and not damaged.

Operation

• Set the specified center of gravity for your model using the scale. Depending on the model, the fence can be used in both directions. When adjusting, make sure that the stop rests cleanly on the guide. For heavier models, we recommend fixing the center of gravity scale to the base plate with a screw clamp.
• Move the rocker to the front stop position. It now has a deflection of exactly 10°. In this position, the stop can be used as an adjustment. The advantage of this method is the exact calibration in a defined position. Furthermore, the fence is away from the model during weighing and does not interfere with the process.
• Your model will no longer slip due to the rubber support. If it does, you can always check the correct position by moving the rocker to the front stop. The model can now be balanced. Also check the light gap at the base of the rocker. If the gap is the same on both sides, the center of gravity has been set exactly.
• The rear stop is used to prevent the model from falling if, for example, the battery is completely removed.
