Step 7. Set up a flight battery timer
Tap on Timer 1 in the Model / Timers section, and select Edit. In this example we are
configuring a Down counting timer, with a Start Value of 5 minutes. The countdown will
start at 2 minutes, and will be called out via speech at 30 second intervals and then every
second from 10 seconds remaining. The timer will run whenever the throttle is not idle
(throttle absolute option), provided it is not being held in reset.
In the example the timer is reset by switch SA-down, which is our throttle hold switch. It is
not persistent, so it will also be reset at power on.
This setup can be used to warn you when it is time to land, with the start value chosen so
that approximately 30% of battery capacity remains. LiPo type batteries do not tolerate
being over-discharged.
