FAILSAFE
If your transmitter can set values for all the channels for failsafe, set the roll &
pitch channels to midstick and the throttle to its lowest setting to stop the motors.
For transmitters that only set failsafe on the throttle channel, set the throttle
to its lowest setting
Be sure to remove the props before testing the failsafe operation.
BATTERIES
The RXD250 has been tested with 3 cell lipos between 1300(30C or larger)
and 2200mAh (20C or larger). Typical flight time is between 4 and 6 minutes.
IMPORTANT!
The flight controller does not have a low voltage cutoff to
protect the lipo from damage. The LEDs on the bottom of the RXD250 will
start flashing when the battery is at 10.2V for a 3S battery. You MUST land
the quadcopter as soon as the LEDs start to flash.
For your first flight, set a timer for 4 minutes. If the LEDs are not flashing at
the end of the flight, the timer setting could be increased to find the optimal
flight time. If the LEDs are flashing at the end of the flight, the timer setting
should be reduced to protect the battery from damage.
We recommend using a voltage monitor/alarm that plugs into the battery’s
balance connector and will sound an alarm when the battery voltage gets low.
WARNING:
Your battery life will be reduced and the battery
can be damaged any time the battery voltage is low enough
for the LEDs to flash. Charging a Lipo battery that is damaged
in any way can pose a fire hazard.
