Product Information:
The Backup Capacitor flight control system is an emergency backup power control device for hobby models, helping to ensure a safe landing in the event of a main receiver power outage.
Main Uses:
Emergency Backup Power:
In the case of your aircraft losing power during flight, the backup capacitor will automatically activate to power the receiver, ensuring continued control over the servos and enabling the aircraft to be safely piloted to the ground.
Dual Control Mechanisms:
- Switch Button Control - Activate or deactivate the backup capacitor's power supply using a physical button.
- Throttle Signal Control - Control is achieved through a 3 pin wire connected to the backup capacitor (orange signal wire). When the throttle frequency is within the range of 50hz to 600hz, a throttle signal value greater that 1500 indicates that the system is in the "on" state. A value less than 1500 indicates that the system is in the "off" state.
Important Notes:
Starting and Shutting Down with Throttle Signal Control:
- Starting - When controlling with the throttle signal, ensure the throttle signal value is set above 1500 before starting the aircraft to activate the backup capacitor's power supply.
- Shutting Down - When shutting down the aircraft, set the throttle value below 1500 to deactivate the backup capacitor's power supply.
Backup Capacitor Charging State:
- Pressing the switch button during the charging process of the backup capacitor will do nothing and will not affect the charging state.
- If you need to turn off the system after the backup capacitor is powered down, this can be achieved by pressing the switch button.
Product Features Summary:
- Provides an emergency backup power source during aircraft flight.
- Dual control methods for increased flexibility and safety.
- Simple and versatile throttle signal control, compatible with a wide range of frequencies.
- Safety measures during the charging state of the backup capacitor.
LED Indicator:
- After the backup capacitor is connected to the receiver, it starts to flash a red light for self-test (for about 3 seconds), and starts to charge automatically after the self-test is completed.
- Charging process, the three blue lights will flash in turn, until all three blue lights are lit, at which point the backup capacitor is fully charged.
