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
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 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
Aircraft banks steeper in
one direction when Virtual
Instructor is set on Training
Step 1 or 2 Incorrect trim when Virtual Instructor is set on Training
Step 1 or 2 Slide aileron and rudder trim 3 clicks in the direction that the model
banks less steep
Stick trim is used to achieve fl ight trim, affecting Vir-
tual Instructor Land and mechanically adjust aileron and/or rudder linkages for
fl ight trim without trim on the transmitter
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
Incorrect Virtual Instructor
response Loose receiver Align and secure receiver in fuselage
