Problem
Unit does not operate
Possible Cause Solution
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
No electrical connection
Check polarity installation or replace with fresh AA batteries
Push connectors together until they are secure
Flight battery is not charged
Crash has damaged the radio inside the fuselage
Rudder or rudder trim is not adjusted correctly Aircraft keeps turning in one direction
Aircraft turns when on the ground, but fl ies straight in the air
Aileron or aileron trim is not adjusted correctly
Nose gear linkage is out of adjustment.
Aircraft is difficult to control Wing or tail is damaged
Damaged propeller
Aircraft nose rises steeply at half throttle
Fully charge the battery
Replace the fuselage or receiver
Adjust stick trims, then land and manually adjust aileron and/or rudder 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
Center of Gravity is behind the recommended location Shift battery forward, do not fl y until correct Center of Gravity location is achieved
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 button, adjust push rod length
Aircraft will not climb
Battery is not installed in the correct position.
Battery is not fully charged
Move forward approximately 1/2”
Fully charge battery before flying
Elevator may be trimmed ‘down’
Propeller damaged or installed incorrectly
Adjust elevator trim ‘up’
Land immediately, replace or install propeller correctly
Launching the aircraft down wind or into a cross wind Always launch the aircraft directly into the wind Aircraft is diffi cult to launch in the wind
Flight time is too short Battery is not fully charged
Flying at full throttle for the entire fl ight
Recharge battery
Fly at just above half throttle to increase fl ying time
Aircraft vibrates
Aircraft banks steeper in one direction when Virtual
Instructor is set on Training
Step 1 or 2
Rudder, ailerons or elevator do not move freely
Aircraft will not Bind (during binding) to transmitter
Wind speed too fast for safe fl ight
Propeller damaged
Propeller, spinner or motor damaged
Incorrect trim when Virtual Instructor is set on Training
Step 1 or 2
Stick trim is used to achieve fl ight trim, affecting Virtual Instructor
Damaged or blocked push rods or hinges
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
Aircraft will not connect
(after binding) to transmitter
After being properly adjusted, aileron and/or rudder are not in neutral position when battery is plugged in
Incorrect Virtual Instructor response
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
Bind plug is not installed correctly
Move the aircraft and transmitter to another location and attempt binding again
Install bind plug and bind aircraft to transmitter
Flight battery/Transmitter battery charge is too low
Transmitter is too near aircraft during connecting process
Replace/recharge batteries
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
Bind aircraft to transmitter Transmitter may have been bound to a different model
(using different DSM Protocol)
Model was moved during initial power on Unplug fl ight battery and reconnect, keeping model immobile for at least 5 seconds
Loose receiver Align and secure receiver in fuselage
