Trouble Shooting Guide
Problem
Possible Cause
Solution
Unit does not operate
There is no link between the transmitter and receiver
Re-Bind the system following directions in this manual
No GPS lock. (or operating indoor without disabling
GPS)
Move to outside and power on aircraft or disable GPS in the aircraft
Transmitter AA batteries are depleted or installed
incorrectly as indicated by a dim or unlit LED on the
transmitter or the low battery alarm
Check polarity installation or replace with fresh AA batteries
No electrical connection
Push connectors together until they are secure
Flight battery is not charged
Fully charge the battery
Crash has damaged the radio inside the fuselage
Replace the fuselage or receiver
Aircraft keeps turning in one
direction
Rudder or rudder trim is not adjusted correctly
Adjust stick trims, then land and manually adjust aileron and/or rud-
der linkages so no transmitter trim is required
Aileron or aileron trim is not adjusted correctly
Adjust stick trims or manually adjust aileron positions
Aircraft turns when on the
ground, but fl ies straight in
the air
Nose gear linkage is out of adjustment
Adjust the nose gear steering linkage on the rudder servo arm so the
model steers straight on the ground when the rudder control is at
neutral
Aircraft does not land on
heading set on initial takeoff
Compass is out of calibration
Calibrate the compass using the “Compass Calibration Procedure”
located in this manual
GPS Function not operating
properly
The compass has been exposed to a magnetic source. Deactivate GPS system while in fl ight and land the aircraft. Remove
any possible magnetic sources such as cameras, camera mounts,
speakers ect. Unplug and reconnect fl ight battery to reactivate GPS
system for next fl ight. Perform compass calibration before fl ying
again.
Aircraft is difficult to control
Wing or tail is damaged
Replace damaged part
Damaged propeller
Land immediately and replace damaged propeller
Center of Gravity is behind the recommended location
Shift battery forward, do not fl y until correct Center of Gravity loca-
tion is achieved
Aircraft nose rises steeply at
half throttle
Wind is too gusty or strong
Postpone flying until the wind calms down
Elevator is trimmed ‘up’ too much
If trim must adjusted more than 4 clicks when pushing the trim but-
ton, adjust push rod length
Battery is not installed in the correct position.
Move forward approximately 1/2”
Aircraft will not climb
Battery is not fully charged
Fully charge battery before flying
Elevator may be trimmed ‘down’
Adjust elevator trim ‘up’
Propeller damaged or installed incorrectly
Land immediately, replace or install propeller correctly
Aircraft is diffi cult to launch
in the wind
Launching the aircraft down wind or into a cross wind
Always launch the aircraft directly into the wind
Flight time is too short
Battery is not fully charged
Recharge battery
Flying at full throttle for the entire fl ight
Fly at just above half throttle to increase fl ying time
Wind speed too fast for safe fl ight
Fly on a calmer day
Propeller damaged
Replace propeller
Aircraft vibrates
Propeller, spinner or motor damaged
Tighten or replace parts
Rudder, ailerons or elevator
do not move freely
Damaged or blocked push rods or hinges
Repair damage or blockage
Aircraft will not Bind (during
binding) to transmitter
Transmitter is too near aircraft during binding process
Move powered transmitter a few feet from aircraft, disconnect and
reconnect battery to aircraft
Aircraft or transmitter is too near a large metal object,
wireless source or another transmitter
Move the aircraft and transmitter to another location and
attempt binding again
Bind plug is not installed correctly
Install bind plug and bind aircraft to transmitter
Flight battery/Transmitter battery charge is too low
Replace/recharge batteries
Aircraft will not connect
(after binding) to transmitter
Transmitter is too near aircraft during connecting
process
Move powered transmitter a few feet from aircraft, disconnect and
reconnect battery to aircraft
Aircraft or transmitter is too near a large metal object,
wireless source or another transmitter
Move the aircraft and transmitter to another location and attempt
connecting again
Bind plug is left installed
Rebind transmitter to aircraft and remove bind plug before
cycling power
Aircraft battery/Transmitter battery charge is too low
Replace/recharge batteries
Transmitter may have been bound to a different model
(using different DSM Protocol)
Bind aircraft to transmitter
After being properly adjust-
ed, aileron and/or rudder are
not in neutral position when
battery is plugged in
Model was moved during initial power on
Unplug fl ight battery and reconnect, keeping model immobile for at
least 5 seconds
