cause a safety hazard! Move the throttle stick and throttle
trim lever to minimum position to stop the glow engine
or shut down the ESC. Once the propeller has stopped
rotating, shut off the ON/OFF power switch in the model,
and disconnect the power battery from the ESC in electric
airplanes. Then turn off the power switch in the Tx.


This radio system includes a “failsafe” function which will

hold the aileron, elevator, and rudder channels at their last
recognized position if the Rx suddenly loses signal from the

Tx. The throttle channel will reduce to a low speed to allow

the model to slowly descend to the ground. When the Rx
regains signal it will automatically resume normal function.
It’s a good idea to test this function on the ground. With the
engine or electric motor unplugged, power the Tx and Rx
and make sure all controls work properly. Turn off power
to the Tx and observe if the airplane’s control surfaces
move to the failsafe settings mentioned above. Re-apply
power to the Tx and confi rm that total control of all aircraft
surfaces is regained.


This device complies with part 15 of the FCC rules. Operation

is subject to the following two conditions.

(1) This device may not cause harmful interference.

(2) This device must accept any interference

received, including interference that may cause
undesired operation.

FCC Rf Radiated Exposure Statement: The equipment
complies with FCC Rf radiation exposure limits set forth
for an uncontrolled environment. This equipment should

be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.






While the SkyFly Max is considered a trainer and is very
easy and forgiving to fl y, if you have never fl own a model

aircraft before, it is strongly suggested that you learn to fl y
with the assistance of an experienced R/C pilot. The following
guidelines will help guide your learning, but should not be
considered a replacement for 1-on-1 instruction.

This model includes a transmitter with a wireless trainer

function that makes training convenient, fun and risk-free.

To use the trainer system, you must fi rst fi nd (or purchase)

a second Tactic TTX404 2.4GHz radio transmitter. The
transmitter is available as a spare part (TACJ0403).

Find a Suitable Flying Site

Find a fl ying site clear of buildings, trees, power lines and
other obstructions. Until you know how much area will be
required and have mastered fl ying your SkyFly Max, a site
at least the size of two or three football fi elds should be
adequate - a fl ying fi eld specifi cally intended for R/C planes

is best. Never fl y near people - especially children who can

wander unpredictably. Consider the wind direction also when
selecting a fi eld. You want to take off and land directly into
the wind if possible.

Perform a Range Check

As a precaution, an operational ground range test should be

performed before the fi rst fl ight each time out. Performing a
range test is a good way to detect problems that could cause
loss of control such as low batteries, defective or damaged
radio components or radio interference. This usually requires
an assistant and should be done at the actual fl ying site you
will be using.

First turn on the transmitter. Check to see that the red light

is lit steady and is not blinking. If it is blinking, replace the
batteries in the transmitter with fresh batteries. Then, install
the fully charged battery into the fuselage and connect it.
Install the canopy (battery hatch).

Remember, use care not to “bump” the throttle stick.
Otherwise, the propeller will turn, possibly causing damage
or injury.

Have an assistant hold the model on the ground, holding it
from the front and making sure to stay clear of the propeller.
Begin walking away from the model, operating the controls
in a predictable pattern (for example: up/down elevator,
right/left aileron, right/left rudder). Perform these checks at
several throttle settings. Have your assistant alert you if the
controls fail to respond or if they move suddenly or erratically.

You should be able to maintain control up to a distance of

approximately 100' [30m].

If the controls respond erratically or if anything else seems
wrong, make certain all the servo wires are securely
connected to the receiver and that the transmitter batteries
are fresh. If you cannot fi nd a mechanical problem with
the model, it is possible that there is radio interference
somewhere in the area. One option would be to try another
range check at an alternate fl ying site.

Monitor Your Flight Time

Monitor and limit your fl ight time using a timer such as the
one on your wrist watch. When the batteries are getting low,
full throttle performance begins to degrade before the ESC
completely cuts off motor power. This may be hard to notice
