Problem
Unit does not operate There is no link between the transmitter and receiver
Transmitter AA batteries are depleted or installed
incorrectly as indicated by a dim or unlit LED on the
transmitter or the low battery alarm
No electrical connection
Flight battery is not charged
Crash has damaged the radio inside the fuselage
Aircraft keeps turning in one Rudder or rudder trim is not adjusted correctly
direction
Aileron or aileron trim is not adjusted correctly
Aircraft turns when on the Nose gear linkage is out of adjustment.
ground, but fl ies straight in
the air
Aircraft is difficult to control Wing or tail is damaged
Damaged propeller
Center of Gravity is behind the recommended location
Aircraft nose rises steeply at Wind is too gusty or strong
half throttle
Elevator is trimmed 'up' too much
Battery is not installed in the correct position.
Aircraft will not climb Battery is not fully charged
Elevator may be trimmed 'down'
Propeller damaged or installed incorrectly
Aircraft is diffi cult to launch Launching the aircraft down wind or into a cross wind
in the wind
Flight time is too short Battery is not fully charged
Flying at full throttle for the entire fl ight
Wind speed too fast for safe fl ight
Propeller damaged
Aircraft vibrates Propeller, spinner or motor damaged
Aircraft banks steeper in Incorrect trim when Virtual Instructor is set on Training
one direction when Virtual Step 1 or 2
Instructor is set on Training
Stick trim is used to achieve fl ight trim, affecting Vir-

tual Instructor
Rudder, ailerons or elevator Damaged or blocked push rods or hinges
do not move freely
Aircraft will not Bind (during Transmitter is too near aircraft during binding process
binding) to transmitter
Aircraft or transmitter is too near a large metal object,
wireless source or another transmitter
Bind plug is not installed correctly
Flight battery/Transmitter battery charge is too low
Aircraft will not connect Transmitter is too near aircraft during connecting
(after binding) to transmitter process
Aircraft or transmitter is too near a large metal object,
wireless source or another transmitter
Bind plug is left installed
Aircraft battery/Transmitter battery charge is too low
Transmitter may have been bound to a different model
(using different DSM Protocol)
After being properly adjust- Model was moved during initial power on

Possible Cause Solution
Re-Bind the system following directions in this manual
Check polarity installation or replace with fresh AA batteries
Push connectors together until they are secure
Fully charge the battery
Replace the fuselage or receiver
Adjust stick trims, then land and manually adjust aileron and/or rud-
der linkages so no transmitter trim is required
Adjust stick trims or manually adjust aileron positions
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.
Replace damaged part
Land immediately and replace damaged propeller
Shift battery forward, do not fl y until correct Center of Gravity loca-
tion is achieved
Postpone flying until the wind calms down
If trim must adjusted more than 4 clicks when pushing the trim but-
ton, adjust push rod length
Move forward approximately 1/2"
Fully charge battery before flying
Adjust elevator trim 'up'
Land immediately, replace or install propeller correctly
Always launch the aircraft directly into the wind
Recharge battery
Fly at just above half throttle to increase fl ying time
Fly on a calmer day
Replace propeller
Tighten or replace parts
Slide aileron and rudder trim 3 clicks in the direction that the model
banks less steep
Land and mechanically adjust aileron and/or rudder linkages for
fl ight trim without trim on the transmitter
Repair damage or blockage
Move powered transmitter a few feet from aircraft, disconnect and
reconnect battery to aircraft
Move the aircraft and transmitter to another location and
attempt binding again
Install bind plug and bind aircraft to transmitter
Replace/recharge batteries
Move powered transmitter a few feet from aircraft, disconnect and
reconnect battery to aircraft
Move the aircraft and transmitter to another location and attempt
connecting again
Rebind transmitter to aircraft and remove bind plug before
cycling power
Replace/recharge batteries
Bind aircraft to transmitter
Unplug fl ight battery and reconnect, keeping model immobile for at
least 5 seconds
Align and secure receiver in fuselage
