14.3.6. Setting up Throttle Check
SETUP
Menu: (
What is Throttle Check?
Throttle Check is a safety query of the throttle control.
This function avoids the danger of power systems
bursting into life unexpectedly, endangering and even
injuring you and others. It is a simple means of improv-
ing safety when operating any powered model.
How does Throttle Check work?
If the Throttle Check function is activated, the transmit-
ter checks whether the throttle control is at the idle
setting every time the transmitter is switched on, and
also when you switch to a different model memory. If
not, the screen continues to display the message
"TH >0" until you move the throttle control to the idle
position. At the same time the throttle channel (receiver
output 4) is held at idle.
When you set up a new model, Throttle Check is al-
ways active (THRCHK = 1).
We recommend:
Don't switch Throttle Check off unless you are sure that
it is not dangerous to switch the model on "with throttle"
(unpowered model, glow motor, speed controller with
power-on guard).
Moving to the TH CHK menu:

to TH CHK,
"0" or "1" flashes in the bottom line.
THRCHK = "1": active (default setting)
THRCHK = "0": no Throttle Check
You can change the THRCHK setting using the 3-D
digi-adjustor.
A brief press on the 3-D digi-adjustor concludes the
setting process. The selecting setting is now stored.

14.4. Adjusting servos

TIP: carry out mechanical adjustments first
It is always advisable to set up the mechanical systems
in the model as accurately as you can before carrying
out any (electronic) adjustments at the transmitter.
• Set the output arm on the servo output shaft at right-
angles to the case. This avoids inadvertently setting
up mechanical differential travel.
• Neutral point:
Set the desired neutral point of the control surfaces
as accurately as possible by altering the length of the
pushrod.
• Servo:
Connect the pushrod as far "inboard" as possible at
the servo output arm, and use the maximum avail-
able servo travel. This reduces the effect of gearbox
play, and exploits the servo's power to the full.
• Control surface:
Connect the pushrod as far "outboard" as possible at
the horn. This reduces the effect of play in the link-
age, and transfers the servo's power to the control
surface as efficiently as possible.
For each of the seven servos you can adjust the follow-
ing parameters:
- the centre
- the travel, separately in both directions
- the direction of rotation (REVerse)
These settings are used to adjust the control surface
travels and the neutral position to suit the requirements
of the model.
We recommend:
First check the direction of rotation, and correct this if
necessary ( 14.4.1.).
Before you change the centre point (neutral position) of
the control surfaces at the transmitter, check and cor-
rect the control surface linkage mechanically at the
model. If the control surface settings are already close
to the neutral point, an offset to the servo centre of no
more than +/- 10% should be sufficient (
The final step is to adjust the servo travels (
