You control the help SAFE™ technology provides while you learn to ﬂy.

As your ﬂying skills grow, decrease SAFE technology assistance. Change

aircraft response at any time by moving the Channel 5 (SAFE Flight mode)

switch on your transmitter.

IMPORTANT: These instructions are for the included DX5e transmitter

(or similar transmitters) with a 3-position switch for Channel 5. If you ﬂy this

aircraft with a Spektrum transmitter other than the included DX5e, refer to

Optional Transmitter Setup and Receiver Setup.

Panic Recovery Mode

If you get into distress while ﬂying in any mode, pull and hold the Trainer

(Panic) Switch and move the control sticks to their neutral position. The

SAFE technology will return the aircraft to a stable attitude, if the aircraft is

at a sufﬁcient height with no obstacles in its path. Release the Panic Switch

to turn off Panic mode and return the current SAFE ﬂight mode. If you get

into trouble and need to go back to Beginner mode for maximum stability,

remember to fully move back the Channel 5 switch.

Activating SAFE Technology

SAFE technology is not active until you advance the throttle past 25%.

Once the SAFE technology is active, the control surfaces may move on the

aircraft. This is normal. The SAFE technology will remain active until the ESC

is turned off.

Understanding Oscillation

In some ﬂight conditions, you may see oscillation. If oscillation

occurs, decrease the airspeed. If oscillation still persists, refer to the

Troubleshooting Guide for more information.

CAUTION: Flying in level forward ﬂight and calm wind conditions

at full throttle in any mode or long high-speed dives may result in strong

oscillation that can damage the aircraft.

If there is oscillation in any mode, decrease throttle immediately. If

oscillation persists, refer to the Troubleshooting Guide.

CAUTION: Beginner, Intermediate, and Panic modes are intended

for the training environment. Flying continuous high-G maneuvers (such

as loops) in Experienced mode for an extended period of time may lead to

inconsistent ﬂight envelope and Panic mode behavior. If this occurs, land in

Experienced mode and power cycle the receiver before ﬂying again.

Launch and Landing Assistance

Take off and landings can be better managed by using the Beginner mode.

If the model is launched incorrectly, or is landing at a less than perfect

attitude, pull and hold the Panic Switch. The model can correct and help to

prevent a crash.

See the Take Off and Landing sections in this manual.

IMPORTANT: A level runway is required for takeoffs in Beginner mode due

to throttle climb assistance.

Failsafe

In the unlikely loss of radio connection, failsafe will turn the aircraft in a

descending circle to the ground, unless the radio connection is restored.

SAFE Technology makes this aircraft a better learning tool,

but you must set yourself up for success in ﬂying:

•SAFE technology is designed as ﬂight assistance, not an autopilot. The pilot

is always in control and required to ﬂy the aircraft at all times

•Follow the instructions provided in this manual to maintain your aircraft in

top ﬂying condition

•Seek qualiﬁed model ﬂying instruction through your local model ﬂying club. A

qualiﬁed ﬂight instructor can propel your advancement in this hobby

•Wind and environment can affect SAFE technology ﬂight performance

•Ensure you have no distractions so you beneﬁt from every moment of ﬂight time

•You must still ﬂy the aircraft away from obstacles and at an altitude that will

allow for a safe recovery
