“Binding” transmitter and receiver

Note: The mx-10 HoTT can be bound in the mode „nor-

mal“ only. Make sure before you start the binding pro-

cess, that the transmitter is programmed in this mode.

See page 88 for mode setting.

Turn the transmitter ON and then power up your recei-

ver: At the receiver, the green LED flashes once briefly,

and then goes out.

The LED on the transmitter lights up green to show that

no bound receiver is connected.

Press and hold the SET button on the receiver until the

green LED starts to flash.

Briefly press the BIND-button of the transmitter to initiate

the so-called binding process

If the receiver LED glows a constant green within about

ten seconds, then the binding process has been com-

pleted successfully; you can now release the receiver’s

SET button.

Your model / receiver combination is now ready for use.

In parallel with this the Status-LED switches from green

to orange:

Conversely, if the green LED on the receiver ﬂ ashes

for longer than about ten seconds or the transmitters

Status-LED remains green, then the binding process

has failed. If this should occur, alter the relative position

of the aerials, and repeat the whole procedure.

range test

The integral range-check reduces the transmitter’s out-

put power in such a way that you can test the system’s

operation at a distance of up to about ﬁ fty metres.

Carry out the range-check of the Graupner HoTT sys-

tem in accordance with the following instructions. We

recommend that you ask a friend to help with range-

checking.

Install the receiver in the model as required, preferab-1.

ly after completing the binding process with the trans-

mitter.

Switch the radio control system on and wait until the 2.

green LED on the receiver glows. Now you can obser-

ve the servo movements.

Place the model on a ﬂ at surface (paving, close-mown 3.

grass or earth), with the receiver aerials at least

15 cm above the ground. This means that you may

have to place the model on a raised object for the pe-

riod of the check.

Hold the transmitter at hip-height, and away from your 4.

body. However, do not point the aerial straight at the

model; instead rotate and / or angle the tip of the aeri-

al so that it is vertical while you carry out the check.

Make sure that the transmitter in the „normal“ mode 5.

- mode switch to the rear. Now press the BIND-but-

ton for about 5 s, until the transmitter starts to beep

permanently. Disengage the BIND-button again. Note

when using multiple receivers for each model: the

range test only works with the receiver which trans-

mits the telemetry signal - that is the last bound re-

ceiver.

When you start the range-check, the transmitter’s 6.

output power is signiﬁ cantly reduced, at the same

time a permament beep sounds. When the 99 se-

conds of the range-check period have elapsed, the

transmitter switches back to full power, and the beep

sound stops. Note: you can stop the range test at

any time by pressing again the BIND button.

Within this period walk away from the model, moving 7.

the sticks all the while. If at any point within a distance

of about ﬁ fty metres you notice a break in the connec-

tion, attempt to reproduce it.

If the model is ﬁ tted with a motor, switch it on in order 8.

to check the system’s interference rejection.

Walk further away from the model until you no longer 9.

have full control over it.

At this point wait until the test period has elapsed, with 10.

the model still switched on and ready for use. When

the range-check period is over, the model should re-

spond again to control commands. It this is not 100%

the case, do not use the system. Contact your nearest

Service Centre of Graupner GmbH & Co. KG.

Carry out the range-check before every ﬂ ight, and si-11.

mulate all the servo movements which are likely to oc-

cur in a typical ﬂ ight. To ensure safe operation of the

model, the range must always be at least ﬁ fty metres

on the ground.

Caution:

Never initiate a range-check when you are actually

operating a model!

Deﬁ nition of terms

Control functions, transmitter controls, function inputs, control channels, mixers, switches, control switches, Smart-Box

To make it easier for you to understand the mx-10

HoTT manual, the following section contains deﬁ nitions

of many terms which crop up again and again in the

remainder of the text.

Control function

The term “control function” can be thought of as the

signal generated for a particular function which needs

to be controlled - initially independent of its subsequent

progress through the transmitter. In the case of ﬁ xed-

wing model aircraft the control functions include throttle,

rudder and aileron, whereas collective pitch, roll and

pitch-axis are typical of those used for helicopters. The

signal of a control function may be assigned directly, or

to several control channels simultaneously via mixers. A

typical example of the latter is separate aileron servos or

a V-Tail. The essential feature of a control function is its

inﬂ uence on the mechanical travel of the corresponding

servo.

Transmitter control

The term “transmitter control” refers to the mechanical

elements on the transmitter which are operated directly

by the pilot. Their movements in turn generate corres-

ponding movements in the servos, speed controllers etc.

at the receiver end. The transmitter controls include the

following:

The two dual-axis stick units for the control functions •

1 to 4; for both model types (“ﬁ xed-wing” and “helicop-

ter”) these four functions can be interchanged in any

way you wish using the “Mode” function, e. g. throttle

left or right, without having to re-connect the servos.

The dual-axis stick function for throttle (or airbrakes) is

often referred to as the Ch 1 (Channel 1) control.

The switch for channel 5•

When a proportional transmitter control is operated,

the servo or servos follow the position of the control

directly, whereas a switched channel provides just the

two or three set servo positions.

Function input

This is an imaginary point on the signal path, and must

not be considered the same as the point on the circuit

board where the transmitter control is connected! The

two menus “Stick mode” and “Transmitter control

settings” affect the course of the signal “after” this point,

and it is possible (and likely) that there will be differences

between the number of the transmitter control (as stated

above) and the number of the subsequent control chan-

nel.

Control channel

There is a point on the signal path where the signal con-

tains all the control information required for a particular

servo – this may be directly generated by a transmitter

control or indirectly via a mixer – and from this point on

we call the signal a “control channel”. This signal is only

affected by any adjustments carried out in the “Servo

settings” menu before leaving the transmitter via the RF

module. Once picked up at the receiver, this signal may

be modiﬁ ed by any settings made in the Telemetry menu

before ﬁ nally passing to the corresponding servo in the

model.

Mixer

The transmitter’s software includes a wide range of mixer

functions. Their purpose is to enable a control function to

affect multiple servos at the branching point of the mixer

input, or alternatively to allow several control functions to

affect one servo. For more information please refer to the

numerous mixer functions of the Smart-Box as described

on page 119 of the manual.

Switch

The standard toggle switch for channel 5 moves the

connected servo to the min./max. position.

Smart Box

The optional Smart-Box allows the use of many other

HoTT functions such as:

• transmitter voltage display with programmable warning

threshold

• Receiver Temperature

• Servo travel

• Channel Mapping

• Mixer settings

• Signal quality

• Receiver Voltage

• Servo neutral position

• Cycle time

• Channel-dependent fail-safe settings

• Servo test

see the section „telemetry“ on page 113.
