 Redundancy: The redundant propulsion system enables a controlled flight 

even with only 5 functioning motors and 

actively compensates for failure. In worst 

case the system would start to sink automatically.

 Telemetry in realtime: All necessary 

system information such as GPS position, 

height, velocity, battery load, link and GPS 

quality for instance is displayed live. 

 Sensor output check: All important 

sensor values and system parameters are 

checked automatically before each flight. 

If a value is critical, it will be identified and 

interrupt the launching procedure automatically.

 3 Emergency modes: The pilot can 

choose one of three emergency modes to 

determine the automatic landing in case 

of link loss: “Direct landing”, “Comehome 

straight” (at its current height) or “Comehome high” (at max. mission height). As soon 

as the link is reestablished you may take 

control again and continue the flight.
