recommended solution for the issue.
If the required solution does not rectify the problem, please contact product support at [email protected] for further assistance.
NOTICE
Unless specifically required, ALWAYS troubleshoot the airplane with the propeller removed.
DISCREPANCY
PROBABLE CAUSE
RECOMMENDED SOLUTION
Motor non-responsive (no ESC
initialization tones audible)
Throttle not at idle and/or throttle trim too high
Lower throttle stick and trim completely. If problem persists, ensure that the sub-trim
and travel adjust are properly set in the radio’s programming
Motor disconnected from ESC
Ensure plugs are fully seated. Check battery and/or plugs for damage and replace any
damaged components found - DO NOT ATTEMPT REPAIR
Motor non-responsive (throttle
calibration tones received)
Throttle channel is reversed
Reverse throttle channel in radio programming
Motor turns in the wrong
direction
The three motor wires are connected incorrectly to
the ESC
Swap any TWO motor wires
Reduced flight time or aircraft
underpowered
Battery not fully charged
Ensure battery is fully charged prior to installing in aircraft
Propeller installed backwards
Install propeller so that the convex side faces forward (tractor configuration)
Battery is too weak or damaged
Remove battery from service completely and replace with a di
ff
erent battery
Ambient temperature is too cold
Ensure battery packs are adequately warm (70°F/21°C) before flight
Battery capacity too small for intended use
Replace battery with one of proper capacity and discharge capacity
ESC reaching preset LVC (low-voltage cuto
ff
)
Recharge flight battery or reduce flight time
Battery’s discharge rating may be too small
Replace battery with one with higher ‘C’ rating
Excessive propeller noise and/
or vibration
Damaged spinner and/or propeller, collet, or motor Replace damaged components - DO NOT ATTEMPT REPAIR
Propeller is not balanced
Balance or replace the propeller
Prop nut is loose
Tighten prop nut with appropriate-sized wrench
Spinner is not fully in place or tightened
Loosen the spinner bolt, adjust as required, retighten spinner bolt
Propeller nut or propeller adapter threads not cut
straight
Replace propeller nut or propeller shaft - DO NOT ATTEMPT REPAIR
Control surfaces
nonresponsive
Airframe or control linkage system damage
Examine airframe for damage, repair as required; inspect control linkage system (servo,
pushrod, control horn) for damaged components and replace as required
Wire damaged or connector loose
Examine wires and connections, replace as necessary
Transmitter bound incorrectly, incorrect active
model memory, incorrect Aura data input
configuration, incorrect Aura transmitter settings
Consult radio manual for proper binding and model selection instructions
Battery voltage too low
Use volt meter to check battery; recharge or replace as necessary
Battery disconnected from ESC
Check that the EC3 plugs are fully seated
BEC (battery elimination circuit) damaged
Replace ESC - DO NOT ATTEMPT REPAIR
Damaged Servo
Replace Servo - DO NOT ATTEMPT REPAIR
Failed control direction test
Incorrect Aura 8 or Transmitter Setting - DO NOT
FLY!
Reference transmitter and receiver sections of this manual. Refer to control surface
direction chart and transmitter setup; adjust appropriate settings as required. Check
Mamba 10 G2 and Aura wiki web pages for additional information. If no solution is
found, contact customer support at [email protected]
Failed Sensor Direction Test
Aura 8 is not mounted in the proper orientation
Mount Aura in the proper orientation
Aura 8 settings incorrect
Reference the transmitter and receiver sections of this manual. If no is solution is found,
contact customer support at [email protected]
Control surface oscillation
Exceeding maximum airspeed for configuration
Reduce airspeed
Gains too high for aircraft/flight configuration
Refer to Aura 8 manual to decrease desired control surface gain
Propeller/spinner not balanced
Balance or replace propeller and/or spinner
Motor vibration
Inspect motor mounting bolts and re-tighten as necessary
Loose Aura 8 mounting
Re-align and secure the Aura 8 to the aircraft
Control linkage slop
Examine control system and repair or replace worn components
Improper transmitter setup
Refer to Aura 8 manual to correctly configure transmitter
Damaged propeller or spinner
Replace damaged component- DO NOT ATTEMPT REPAIR
Improperly set master gain
Ensure master gain is set for proper gain value
Trim changes between flight
modes
Trims are not properly zeroed
Readjust control linkage and re-center trims in radio
Sub-trim is not properly zeroed
Remove sub-trim; adjust the servo arm or clevis to achieve proper geometry
Transmitter is not properly calibrated (aileron/
elevator/rudder are not neutral with sticks
centered; reference transmitter monitor
Calibrate transmitter (reference manufacturer’s instructions, or return to manufacturer
for calibration
Gyro doesn't respond to
aircraft movements
Gyro kill switch not setup on transmitter
Follow the transmitter configuration guide, assign CH7/Aux2 to a two-position switch
Gyro kill switch in o
ff
position
Move the gyro kill switch to the on position
