Corner Weight System

Thank you for purchasing SkyRC Corner Weight System. This Corner Weight System is designed for serious
racers to measure their cars’ corner weight distribution easily, and make necessary weight adjustment to
balance their cars for the best performance.

Corner weight scales allow precise car weight distribution which is critical to on track success. The four corners
of the car may be bearing different amounts of the car weight. The unequal corner weights can be felt as the car
rolling more when turning in one direction than the other. The car’s stability is compromised which will adversely
affect its balance. A well balanced car is generally easier to drive quicker due to increased the car’s stability.

To make sure weight percentages are correct, computerised scale system must be used. Correct chassis setup
separates the front runners from the followers. Corner Weight Scales provide the necessary data for anyone to
become a chassis expert.

Ideally the car should have 50% of its weight on the Left Front and Right Rear tires, and 50% on the Right Front
and Left Rear. If your car's diagonal corner weights are not equal then its handling will be unbalanced--it will turn
better in one direction than in the other (all other things being equal).

This product consist of one main unit and four separate scales, the maximum weight limit for each scale is 2000
grams.
