Tips to maximize range:
10) Prepare for Calibration
This process will take into account your gate size, video transmitter, track layout and lap time
The calibration process sets the sensitivity of the RaceTracker. It can be though of as a bubble. When your quads video transmitter passes through the bubble, the RaceTracker will trigger a lap.
Hold the quad 1.5 - 3.0 gate lengths from the RaceTracker when calibrating. The calibration will take into account this distance and the Video Transmitter power. So it will be different for each setup.
11) Calibrate the RaceTracker
Ignore the presets, power on your Quad to the same frequency as the RaceTracker and tap calibrate
