VStabi Pioneer of Flybarless

During Initialization, the VBar goes through a self-test. The helicopter must be at rest during this test. While the self-test occurs, the V flashes red briefly (Blueline Sensor) or green (Silverline Sensor). When the test is finished, you will see a brief twitching (jump) of the swash plate. Also the V will be lit up continuously, cycling the colors red-blue-green.
