Optional SAFE+ GPS Upgrade
RTF/BNF Basic
The Delta Ray One receiver includes SAFE technology out of the box.
The Delta Ray One aircraft is upgradable with the addition of the optional EFL9512 GPS module (not

on its own, return home and land by itself, and prevent the model from fl ying too far from the pilot.
IMPORTANT:
Read the information in this manual covering the optional SAFE+ GPS upgrades, and
learn the use of Holding Pattern and Autoland modes before fl ying with GPS. SAFE+ features are only
available with the SAFE+ module installed and properly calibrated.
