AIRCRAFT TROUBLESHOOTING GUIDE
Should you encounter any abnormal situations with your Mamba 10, refer to the matrix below to determine the probable cause and a
recommended solution for the action.
If the required solution does not rectify the problem, please contact product support for further assistance.
NOTICE
Unless specically required, ALWAYS troubleshoot the airplane with the propeller removed.
20
Trims are not properly zeroed
Ensure battery packs are adequately warm (70°F/21°C) before ight
Install propeller so that the convex side faces forward (tractor conguration)
DISCREPANCY PROBABLE CAUSE RECOMMENDED SOLUTION
Motor nonresponsive (ESC
intialization 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.
Throttle channel is reversed Reverse throttle channel in radio programming
Motor nonresponsive (no ESC
initialization tones audible)
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 turns in the wrong
direction
The three motor wires are connected incorrectly
to the ESC
Swap any TWO motor wires.
Ensure battery is fully charged prior to installing in aircraft
Propeller installed backwards
Flight battery damaged
Ambient temperature is too cold
Battery capacity too small for intended use Replace battery with one of proper capacity and discharge capacity (C rating)
Battery is too weak or damaged Check battery’s physical condition, check battery voltages after charge
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
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 conntections, replace as neccesary
Transmitter bound incorrectly, incorrect active
model memory, incorrect Aura data input
conguration, 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
Controls reversed Aura 8 or transmitter settings incorrect
Refer to control surface direction chart and transmitter setup; adjust appropriate
settings as required. Check Mamba 10 and Aura wiki web pages for additional
information. Contact customer support at support@exinnovations.com
Control surface oscillation
Reduce airspeed
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 work components
Improper transmitter setup
Trim changes between
ight 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
Damaged propeller or spinner Replace damaged component- DO NOT ATTEMPT REPAIR
Refer to Aura 8 manual to decrease desired control surface gain
Propeller nut or propeller adapter threads not
cut straight
Replace propeller nut or propeller shaft - 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. If no solution found,
contact customer support at support@exinnovations.com
Improperly set master gain Ensure master gain is set for proper gain value
Reduced ight time or
aircraft underpowered
Remove battery from service completely and replace with a dierent battery
ESC reaching preset LVC (low-voltage cuto) Recharge ight battery or reduce ight time
Exceeding maximum airspeed for conguration
Gains too high for aircraft/ight conguration
Refer to Aura 8 manual to correctly congure transmitter
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
Any of four PWM servo cables are not connected Connect all four male to male servo cables between your receiver and Aura
PWM servo cables connected to incorrect ports Reconnect cables to proper ports. Reference chart on page XX
Polarity of PWM servo cables not correct
Receiver not bound and/or outputting PWM
servo pulses
Bind receiver per manufacturer instructions and verify with a servo to ensure
PWM signal is output from each channel as required.
PWM connection type and
cannot get orange+green
Aura and control of model
Reconnect servo cables with proper polarity. Reference chart on page XX
