Gyro start up
Depending on the connection version chosen, set the potentiometer or the steering channel of
the transmitter for the gyro setting at 50% of the control range.
To do this you must use a small screwdriver to turn the left deviation of the potentiometer in the
gyro to the right in a clockwise direction.
Now turn on the transmitter and then the receiver. The gyro component begins the calibration
process. The red LED lights up and the green LED (see Figure 2, pos. 8) blinks in a slow
rhythm. When the gyro is calibrated, only the red LED remains lit.
Important:
While the gyro is calibrating, neither the model nor the steering element can be
moved. If they are, then the gyro may not function correctly.
In such a case, turn the receiver off. Wait ten seconds and then turn it on again and
let the gyro calibrate again.
Now check the function of the gyro by pivoting the rear of the model with a small push (see
Figure 3).
The green LED lights up while the steering servo is run by the module and the steering wheel
of the model must also swerve briefly to the left.
If this does not happen, then the gyro's operating direction must be changed. To do this shut
the receiver off. With a suitable tool (for instance a small screwdriver) the reverse switch (see
Figure 2, pos. 7) must be altered. Turn on the receiver again and check for the correct rotational
direction of the steering servo.
Now carry out another driving test and – depending on the connection version – adjust the
potentiometer or the changes of the steering element on the transmitter to attain the best gyro
setting.
The best setting is found when the model, for example, does not swerve at all or so quickly
when accelerating or taking curves at higher speeds.
Important:
In principle the use of the gyro model, due to the continuous correction of the stee-
ring servo, increases both the current input as well as the burden of the steering
servo greatly.
For this reason you should use adequately large components for the steering servo
as well as the receiver current input.
If the gyro is not correctly adjusted, then the current demand can increase even
more thus naturally making even greater demands on the receiver current input.
If the receiver current input is supplied by a so-called BEC (an external, electronic
module for receiver current input; generally integrated into electronic cruise control),
this could lead to an overload.
The gyro's sensitivity is set too high when there is "fishtailing" when it is in use. In
this case the model does not drive straight but continuously swerves about.
Regardless of the adjustment of the transmitter to the steering servo (end right/
left swerving, adjustment values to dual rate or exponential), if the gyro is set to an
excessive sensitivity it will follow the greatest possible servo path (100% of the pos-
sible steering path). If this causes the servo to start to swerve mechanically, it could
lead to damage to the servo mechanism and/or its electronic functions. Reduce the
sensitivity so that the steering servo cannot cause a mechanical swerve.
