the correct positions. Check that the throttle stick is in the
lowest possible position, and that the throttle trim is set to
the middle or a lower-than-the-middle position. If you now
have control of the motor, proceed to the next step of the
checklist.
If the blinking red status LED keeps flashing, you do not
have a positive RF link between the transmitter and
receiver. Check to be sure that the transmitter has been
powered on and that the LED indicator on the transmitter
is glowing solid red. If the transmitter is powered on and
functioning properly, disconnect the flight battery from
the receiver unit, then reconnect it. Now the receiver unit
should initialize and arm properly.
Note: In the event you inadvertently enter Bind Mode, the
LED on the receiver will flash red continuously.
If this occurs, cycle the flight battery while the
transmitter is on (if previously bound). If your receiver
unit will not initialize and arm after following the
guidelines as listed above, call the Horizon Support
Team at 1-877-504-0233, Horizon Hobby UK at +44
(0) 1279 641 097 or Horizon Technischer Service,
Germany at +49 4121 46199 66.
Once you have placed the airplane in a safe area, free of
obstructions, and are clear of the propeller, you can safely
begin to power up the model to check for proper operation
of the motor.
• Advance the throttle stick upward slowly, just until the
propeller begins to spin. DO NOT attempt to fly the
airplane at this time. Note the direction the propeller spins.
If viewed from the front of the airplane, the propeller will
spin counterclockwise. If it is spinning backwards,
disconnect the battery and reverse the polarity of the
motor’s input power leads.
Reversing Flight Controls
The transmitter included with the RTF J-3 Cub is the same
transmitter that is included in the PKZ Ember 2, Vapor, and Ultra-
Micro P-51 RTF versions. It also functions identically to the
transmitter included with the E-flite Blade ® mCX and
mSR (MLP4DSM).
Note: For reversing with other transmitters, please
refer to that transmitter’s instruction manual.
Should the J-3 Cub’s electronic components be used in another
aircraft, you may find it necessary to reverse the operation of
flight control surfaces.
Reversing the rudder and elevator operation can be
accomplished by following the steps below.
1. Be certain that the battery is unplugged from the aircraft
and the transmitter is turned off.
2. Push down on the digital trim button for the surface you
would like to reverse.
a. Top elevator trim button—elevator normal
b. Bottom elevator trim button—elevator reverse
c. Left rudder trim button—rudder normal
d. Right rudder trim button—rudder reverse
3. Continue holding the desired digital trim button down and
turn the transmitter on.
4. Hold the digital trim buttons down for approximately five
seconds until tones are heard, confirming the selection.
5. Connect the flight battery and complete the flight
control test, confirming that all surfaces are operating in
the correct direction.
