When taking off from a boat there needs to be sufficient space, otherwise the drone should be placed on
the water for take-off. Likewise, it is safer and easier to land the SD4 on the water beside the boat rather
than landing on a rocking boat or where there is insufficient space for a safe landing.
If the boat is rocking, the SD4 may not arm its motors in GPS mode. In this case, carefully take-off in
ATTI mode and then switch to GPS mode if there are sufficient satellites.
For safety, it is not recommended to launch or land your SD4 from your hands.
Be aware of the direction of the wind relative to the boat. Even when at anchor, it is possible that the
wind will not be at the nose of the boat.
Always try and take off with the wind so that the drone will be taken safely away from the boat. When
landing the drone onto a boat, if possible land against the wind so that the drone will be held away from
the boat. The controls of the SD4 are useful to finely control and balance the drone position.
Water Power-Flip
If the drone becomes inverted on the surface of the water, using the Power-Flip feature, the
drone can be flipped so that it is right-side up.
With the drone floating upside-down, pull both the left and right
joysticks simultaneously down and inwards and maintain this
position for 3 seconds. The drone will now be flipped.
