Troubleshooting Guide (SAFE™)
Problem Possible Cause Solution
Control surfaces not at
neutral position when
transmitter controls are at
neutral
Control surfaces may not have been
mechanically centered from factory Center control surfaces mechanically by adjusting the U-bends on control
linkages
Aircraft was moved after the flight
battery was connected and before
sensors initialized
Keep the Aircraft upright and immobile
for 5 seconds after connecting the
battery
Aircraft flies inconsistently
from flight to flight Trims are moved too far from
neutral position Neutralize trims and mechanically adjust linkages to center control surfaces
Controls oscillate in flight,
(Aircraft rapidly jumps or
moves)
Propeller is unbalanced, causing
excessive vibration Remove propeller and rebalance or replace it if damaged
Nut on prop shaft is too loose,
causing excessive vibration Tighten the prop shaft nut 1/2 turn
Aircraft does not connect
to transmitter after battery
is connected
Aircraft is not upright and immobile
after battery is connected Keep the Aircraft upright and immobile for 5 seconds after connecting the
battery
Problem Possible Cause Solution
Aircraft will
not respond
to throttle but
responds to
other controls
Throttle stick and/or throttle trim is
too high Reset controls with throttle stick and throttle trim at lowest setting
Throttle channel is reversed Reverse throttle channel on transmitter
Motor is disconnected from receiver Open fuselage and ensure the plug for the
motor is properly installed
Extra propeller
noise or extra
vibration
Damaged propeller, prop shaft or
motor Replace damaged parts
Nut on prop shaft is too loose Tighten the prop shaft nut 1/2 turn
Troubleshooting Guide
Binding Procedure
1. Make sure the flight battery is disconnected from the aircraft. 4
2. Ensure the transmitter is powered OFF.
3. Connect the flight battery to the aircraft and turn the aircraft upright. The
receiver LED will begin to flash (typically after 5 seconds).
4. Make sure the transmitter controls are at neutral and the throttle is in the
low position.

5. Put your transmitter into bind mode by pushing the left control stick
vertically into the case (until it clicks) while powering ON the transmitter.
6. After 5 to 10 seconds, the receiver status LED will become solid,
indicating that the receiver is bound to the transmitter. If the LED does not
turn solid, refer to the Troubleshooting Guide at the end of the manual.
7. Disconnect the flight battery and power the transmitter off.
Re-Binding the RTF Transmitter
Your Sport Cub RTF transmitter comes pre-bound to the aircraft. If you need to re-bind your aircraft, follow
this binding table.

Problem Possible Cause Solution
Reduced flight
time or aircraft
underpowered
Flight battery charge is low Completely recharge flight battery
Propeller is installed backwards Install propeller with numbers facing forward
Flight battery is damaged Replace flight battery and follow flight battery
instructions
Flight conditions may be too cold Make sure battery is warm before use
Battery capacity is too low for flight
conditions Replace battery or use a larger capacity battery
LED on receiver
flashes rapidly
and aircraft
will not bind
to transmitter
(during binding)
Transmitter is too near aircraft during
binding process Power off transmitter, move transmitter a larger distance from aircraft, disconnect and
reconnect flight battery to aircraft and follow
binding instructions
Bind switch or button was not held
while transmitter was powered on Power off transmitter and repeat bind process
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Move aircraft and transmitter to another
location and attempt binding again
LED on receiver
flashes rapidly
and aircraft will
not respond to
transmitter (after
binding)
Less than a 5-second wait between
first powering on transmitter and
connecting flight battery to aircraft
Leaving transmitter on, disconnect and
reconnect flight battery to aircraft
Aircraft is bound to a different model
memory (ModelMatchTM radios only) Select correct model memory on transmitter
and disconnect and reconnect flight battery
to aircraft
Flight battery/transmitter battery
charge is too low Replace/recharge batteries
Transmitter may have been bound to
a different model (or with a different
DSM Protocol)
Select the right transmitter or bind to the new
one
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter
Move aircraft and transmitter to another
location and attempt connecting again
Control surface
does not move Control surface, control horn, linkage or servo damage Replace or repair damaged parts and adjust controls
Wire damaged or connections loose Do a check of wires and connections; connect
or replace as needed
Flight battery charge is low Fully recharge flight battery
Control linkage does not move freely Make sure control linkage moves freely
Controls
reversed Transmitter settings reversed Do the Control Direction Test and adjust controls on transmitter appropriately
Motor loses
power Damage to motor or power components Do a check of motor and power components for damage (replace as needed)
Nut on prop shaft is too tight Loosen prop shaft nut until propeller shaft
turns freely
Motor power
pulses then loss
of power
Battery power is down to the point of
receiver/ESC Low Voltage Cutoff (LVC) Recharge flight battery or replace battery that is no longer performing
Servo locks or
freezes at full
travel
Travel adjust value is set above 100%
overdriving the servo Set Travel adjust to 100% or less and/or set sub trims to Zero and adjust linkages
mechanically
