Mega ESC Adjustment Mode
Driving Fundamentals
We design all ARRMA cars to be fun and quick to get used to. However, it is important to be
comfortable with the handling before exploring the upper reaches of your car's performance.
For the fi rst run we recommend taking your kit to an open, fl at area (such as a park) ensuring
you are away from potential hazards, people or animals.
Start by simply driving round in a large loop, slowly building up speed to get used to the handling.
Alter the size of the loop and your speed. Watch out for the rear-end of the car breaking loose.
If the car does slide try to counter-steer into the skid and accelerate out or let-off the throttle
and let it come to a stop.
To take a corner you need to slow down before the corner, hold your speed through the curve
and, once you see an exit line, accelerate out of the corner.
Once you have practiced the basic dri v ing techniques and you are comf or table w ith the
performance of the car you can start to open-up the full performance potential of your car.

ARRMA ESC Factory Settings
7-Cell (8.4V) NiMh Batteries
The original setting of the ARRMA MEGA waterproof ESC are shown in the
chart.
As standard the ESC will be set in either Auto or NiMh battery mode. Please
ensure that you select the correct battery mode for the battery type you are
using.
The gearing and motor turn of your kit is specifi cally designed for either a 6-Cell
(7.2V) NiMh or a 2S (7.4V) LiPo battery.
Fitting a 7-cell (8.4V) battery to your kit is possible, however ARRMA recom-
mend changing the motor to a 17 turn or higher motor. Failure to do so may reduce the life-
time of your ESC and motor as well as reduced performance and runtime.
To see the range of ARRMA motors available please visit ARRMA-RC.com or speak to
your local model shop for options/recommendations.
