12. Notes:
A. Before the truck is connected to the battery, please adjust the
speed button (CH3) on the remote control to the center.
B. It is best not to turn the speed button (CH3) when the truck is
running. We also recommend adjusting the speed only after it
stops running.
C. Only the ESC is waterproof. The receiver, motor and servo
need further waterproof processing before driving in or through
water.
D. Do not switch speeds while walking or running. Otherwise,
the transmission may get damaged or go out of control. When
transmission is working under 2-speed, braking should be
operated under 2-speed as well. If braking is done under 1-speed
by mistake, the huge speed difference won’t allow the speed-
changing gears to be matched properly, resulting in lost of
control.
