Skycat Flight Terminator is a combination of a trigger and flight terminator. It disconnects any low current power cable during ejection, typically the autopilot power source (+ side). Most modern ESCs shut motors down once the signal from the autopilot is lost.

The unit listens to a PWM signal from your Drone's radio and, upon command, transfers energy from a Drone battery or dedicated battery to the launcher. Two or more triggers are supported for redundancy.

Reliability is the first priority of the Skycat Flight Terminator. The autopilot will not shut down even in the case of a total power loss to the terminator, which is usually not the case with common electronic flight termination systems. The relay conducts power when it's in mechanical resting state - that is without controlling power.

When the parachute is ejected, electricity is conducted to the launcher's Fuse® release mechanism and to the relay at the same time.

The relay can handle maximum 10A / 12V and it is manufactured by Bosch, a German quality manufacturer of reliable and proven relays commonly used in the automotive industry.


  • Parachute battery: 2S - 4S
  • Receiver voltage range: 4.9V - 6.1V
  • Receiver wire length: 15cm / 5.9in
  • Before using the flight terminator, always check how your aircraft's ESCs behave when the autopilot power cable is disconnected. Some ESCs shut down immediately while others may have a delay or keep running in failsafe mode.
