Red Bull Racing RB7: Step by Step
SETTING UP
THE SERVOS
THE THROTTLE, BRAKE AND STEERING OF YOUR RB7 RACER ARE OPERATED BY THE
SERVOS VIA THREE CONNECTING RODS. PROPER ADJUSTMENT OF THE SERVOS
AND THE RODS IS ESSENTIAL FOR PRECISE CONTROL OF YOUR MODEL.
As the last links in the chain, the remote control servos
and rods transfer all the commands of the RC driver to the
steering mechanism, the throttle and the brake. At rest, the
steering wheel on the transmitter should be in its central
position, and the steering servo and steering linkage
should assume their neutral, or zero, positions, so that the
model drives straight. At first, however, this is unlikely to
be the case, and you can't see whether the round-toothed
pinion of the servo is centred. There is a similar problem
with the throttle and brake servo.
By Stages 20 and 86, you will have set up the horns of the
steering and the throttle and brake servos so that they are
straight, but to establish their actual zero positions, you
have to adjust them when the RC system is in operation.
THE NEUTRAL POSITION
When you have checked that there are fresh cells in both
battery compartments (four in the model and four in the
base of the transmitter), and that the onboard electronics
are correctly connected, switch on the transmitter. The two
LEDs below the words BAT LEVEL should light up.
If one of the servo horns of your model moves from its neutral
position when switched on – as this throttle/brake servo horn has –
you will have to correct its position.
The throttle and steering trim controls are in their central (neutral) positions
when the small indent on the top of each knob is in line with the small white
433
arrowhead above the circular scale.
