Maintenance
The X55 is designed to be modular and low maintenance. It is strongly recommended to follow the table below to regularly inspect the X55 to avoid potential failure. Contact info@arcskytech.com if you have any questions.
Determining Accrued Flight Time
To determine the flight hours, look up STAT_FLTTIME in the parameters using Mission Planner or QGC. This is the total flight time in seconds. To get hours, simply divide by 3600. With Arcsky ArduPilot firmware version 4.3.7 and later, you will see flight hours displayed on the messages tab of QGC and Mission Planner about 1 minute after boot-up.
