Overview and Setup
WARNING:
HEATSINK MAY
BE HOT
The MEGA waterproof brushed ESC (electronic speed controller) is
designed for use with ARRMA brushed motors and is automatically
setup for use with 7.2v Nickel Metal Hydride (NiMH) batteries and
requires no maintenance. The MEGA brushed waterproof ESC
has a status LED, which tells you if the ESC and/or radio-gear are
performing correctly. Use the chart below to understand the LED’s
meaning:
The correct battery mode will stop the car operating if the battery voltage drops below a certain point. The Settings available on the
MEGA brushed waterproof ESC are shown in the chart above. Setting the correct battery mode rather than using the auto mode is
safer and will provide greater performance.
To adjust the battery mode you will have to enter the adjustment mode of the MEGA waterproof ESC. This will also allow you to
change some of the performance parameters of your ESC to tune it for your preferred driving style.
OVER TEMPERATURE PROTECTION:
The MEGA brushed
electronic speed controller will turn off intermittently and not allow
full drive when the temperature of either the motor or the ESC
becomes too high. If activated please allow to cool before continuing
use.

BATTERY MODE:
Lithium polymer (Lipo) or Litium Iron (LiFe)
batteries require special care. The voltage of these batteries must
not drop below a certain level. If these types of battery are 'over-
discharged' they are no longer usable. If using these types of
batteries it is vital that you set the MEGA ESC to the correct battery
mode to stop the batteries overdischarging.

Steering/Throttle Trim
Reversing Steering/Throttle Channel
Dual-Rate Adjustment
Check that the transmitter and receiver
are switched on then position the car so that the front
wheels are off the ground. Look down on the tops of the
wheels and adjust the steering using the steering trim
buttons on the top of the ARRMA transmitter. A short
beep will be heard; A quick double beep means you are at
zero adjustment and a long beep signifi es that you have
reached the end of the trim adjustment.
To adjust throttle trim, switch off your ESC and use
the throttle trim buttons on top of the ARRMA ATX
transmitter until you hear a quick double beep. This
means you are at zero/neutral. A long beep means you
have reached the end of trim adjustment.
If the steering direction is reversed - i.e left goes right, check that the
transmitter and receiver are switched on then simply hold both the steering
trim buttons on the top panel; a long beep will sound and the steering LED
will light (or go out if already lit) which signifi es that the channel has been
reversed.
If you need to reverse the throttle direction, make sure that the ESC is
switched on and the cars wheels are off the ground. Then reverse the
throttle channel by holding the two throttle trim buttons until a long beep
is heard and the throttle LED is lit (or goes out if already lit). The models
wheels will rotate on their own as the ESC neutral throttle position needs to
be reset. To do this, switch the model off and on again and the ESC will chime
to signal it has set the new throttle neutral position.
The dual-rate adjuster at the front of the ARRMA ATX transmitter allows you to adjust the sensitivity
of the steering. Adjusting the dual rate can be useful when running at high speed or on very loose
surfaces where large steering inputs could cause you to lose control of your car.
To reduce the steering dual-rate fi rst check that the transmitter and receiver are switched on then
turn the adjuster, at the front of the ARRMA ATX transmitter, to the left. It has 10 levels of adjustment
and will beep each time an adjustment is made; a long beep signifi es you have reached the end of the
adjustment. To increase the steering dual rate, turn the adjuster to the right; again a long beep means
you have reached the end of the adjustment.
Wheels must be off
the ground before
reversing the
throttle channel.
