A remote control UAV test system was designed for assessing control level of the flight controllers.During the test, the flight controller should control the UAV to take off, fly according to the setting flight path, spot hover and fixed-point land.The system used IG-500N to acquire real-time UAV flight status and sent it to the computer by radio modem.The software based on labview extracted the data corresponding to every test project and analyzed these data to obtain control level indicators that would be imported into the test report.Experiment results showed that the test results output by the system were consistent with data analysis.So the test report is credible and the system can be used to provide a basis for assessing control level of the flight controllers.
