§
g) Connecting the Driving Battery to the Speed Controller
Before connecting the driving battery to the speed controller, activate the transmitter (see chapter 8. c) d) und e). Also
check that the speed controller is switched off
§
Off On
¨
To prevent a sudden starting of the wheels and therefore an uncontrolled starting of the model (e.g. if the
trimming for the drive is maladjusted), place the model vehicle on a suitable surface (or starting box), so
that the wheels can turn freely in case of an error.
Do not reach into the drive. Do not hold the wheels
Now connect the driving battery to the speed controller. Ensure correct polarity (red cable = plus/+, black cable =
minus/-).
h) Switching on the Speed Controller
Switch on the speed controller (see chapter 8 g, figure 1) Then wait for a few seconds (leave the throttle/brake lever on
the transmitter in the neutral position; do not move it).
If the drive of the vehicle starts although the throttle/brake on the transmitter is in the neutral position, then
adjust the trim on the transmitter until the engine stops. If the trim is not enough, then it is necessary to
programme the neutral position, see chapter 10. a).
Now check the drive and steering function of the vehicle.
For programming the speed controller, please observe chapter 10.
Chapter 10. a) describes how the neutral and full throttle positions for forward and reverse driving are to be
programmed. This should be done at first start-up if the steering servo does react correctly but the vehi-
cle’s engine does not start.
Chapter 10. b) describes the other programming possibilities for the speed controller (e.g. braking function
etc.). The manufacturer has already performed a suitable pre-programming. It should not be changed for
the first few attempts at driving.
