The app uses a slider control or manual value entry to specify the weight on the cars wheels. The aim of the slider control is that once the user is used to using the slider input, that method of input will be quicker than manual value entry.
Weight balance is a critical part of car setup, as it has a major impact on car handling.
In addition to the app, 4 micro scales are required - one for each wheel of the car being balanced. It's recommended that the micro scales support weights of up to 1000g for balancing RC cars. This weight limit should be fine for 1/10 on-road and off-road cars. Higher weight limit scales may be required for larger cars.
