i. To initiate the mission, flip the top left switch on the Taranis remote to 

swap from "nanocl" to "Auto" Flight mode.

ii. HyDrone or EchoBoat will start on its mission shortly after switching from 

Manual to  Auto  mode  on  the  Taranis  remote.  “Write  WPs”  alone  will 

NOT  start  the mission.

Important: AutoNav 

does not 

have collision avoidance. User should flip to manual mode for 

obstacle avoidance and maintain line of sight on the USV always.  

AutoNav 

does

 have a return to home function. It is not set up on the transmitter. To activate, 

click back onto Flight Data. Below the HUD, click on Action Tab. Click RTL(Return to Launch) 

BE AWARE, IT WILL HEAD DIRECTLY TO THE POINT YOU ARMED. If there are objects in 

the way or you armed on shore, it will try and go through it.
