Servo Settings; Fail-Safe - GRAUPNER mx-10 HoTT Set Programmierhandbuch

Servo settings

Servo direction, centre, travel
The mx-10 HoTT can adjust the servo direction and
servo travel - dual rate.
Servo rotating direction
The direction of servo rotation can be adjusted to suit
the actual installation in your model. This means that
you don't need to concern yourself with servo directions
when installing the mechanical linkages in the model,
as you can reverse them as and when necessary. The
rotationg direction is be set individually for each channel
with the servo reverse - switches on the front of the
transmitter. The direction is symbolized by „NOR" for
normal rotation and „REV" to reverse the direction of
rotation.

Servo travel „Dual Rate"
To adjust servo travel symmetrically, i. e. to adjust travel
equally on both sides of neutral for elevator, rudder and
aileron. The adjustment range is fi xed and can be selec-
ted between 70% (switch in lower position) and 100%
(switch in upper position) of servo travel.

Note:
With the optional Smart-Box the servo travel can be
programmed separately and also asymmetrically for all
channels. See the section „telemetry" on page 113.

Fail Safe
In its default state (as delivered) the receiver is set to
Hold" mode, i.e. if a fail-safe situation occurs, all the ser-
vos connected to it maintain the last position detected
as valid. In this mode the green LED on the receiver
expires when interference occurs, and the orange LED
on the transmitter starts fl ashing 3-times for a short pe-
riod. In addition the transmitter also starts beeping in the
same way like the Status-LED as an audible warning.
You can exploit the safety potential of the fail-safe option
by at least programming the throttle channel to respond

100 % to a fail-safe situation: the throttle channel of an engine-

powered model should be set to idle, the throttle channel
70 %
of an electric-powered model to "stop", and the throttle
channel of a model helicopter to "Hold". If interference
should occur, these settings will help prevent the model
fl ying out of control, possibly causing personal injury or
property damage.
IMPORTANT:
The two functions "Binding" and "Range check" descri-
bed above can be used regardless of the method you
last employed to program the transmitter, i.e. using
the programming button or the SMART-BOX; neither
of these two options causes signifi cant changes to the
settings saved in the receiver. However, if you call up
the Fail-Safe function using the programming button
as described below, this resets ALL the settings of the
SMART-BOX at the Fail-Safe screen (RX FAIL SAFE)
- and this includes the settings available through the
facilities of the programming button. At the same time
the Country setting will revert to Universal if you have
previously selected "France" using the programming
button. You MUST therefore select the Country setting
again if necessary. For this reason, wherever
