Optional SAFE+ GPS Upgrade
Flying the Delta Ray One with SAFE+
• Sensor Assisted Flight Envelope (SAFE
®
Plus)technology is designed as fl ight assistance, not an
autopilot. The pilot should fl y the aircraft at all times.
• Start in Beginner mode (Flight Mode switch position 0). As you learn and become more confi dent,
change modes to advance your fl ying skills.
• Fly your aircraft outside in no greater than winds up to 12 mph (16 km/h).
• Always launch your aircraft directly into the wind if possible.
• For indoor fl ight, turn off the GPS to fl y the aircraft inside buildings like a large gymnasium.
• When fl ying in Autoland mode, the aircraft fl ight path may be adjusted with the transmitter controls,
release the controls to let the GPS system resume command.
• The Delta Ray One with SAFE+ technology added does not have obstacle avoidance technology, be
prepared to guide the aircraft if it is headed toward a tree or other object.
In-Flight GPS OFF
The GPS can be turned off during fl ight
at any time by pressing and holding
the trigger while toggling the fl ight
mode switch back and forth three
complete cycles. This will disable all GPS features
(Virtual Fence, Holding Pattern and AutoLand)
and allow pilot to manually control the aircraft.
• If GPS is lost in fl ight or the GPS is installed
backwards the aircraft wags the wing right
then left then pitches up then down then the
motor pulses like low battery.
• If GPS is turned off in fl ight manually you see
the same wag and pitch with no motor pulse.
IMPORTANT:
If you experience GPS signal loss,
perform a compass calibration before your next
fl ight.

release the HP/AL trigger again to exit.
