    It is useful to have different settings and trims for specific flight phases when flying models. The flight phases technology in the PROFI TX provides an easy and convenient way to realize this. You can copy settings for one flight phase to another, disable flight phases if they are not needed, assign switches to flight phases, etc.

  • Page 102: Training (Principle)

    The teacher transmitter requires a receiving device for the student signal. On older transmitters with DIN socket, the trainer stick is the receiving device; the PROFI TX uses the COPILOT module. The trainer stick or the COPILOT module are bound in the same way to the student transmitter (binding procedure) as receivers.

    Refer to section 4.4.5 "Gyro" on page 128 for more information.  Damping mode The gyro operates in Damping mode if sensitivity is set to positive values.  The gyro operates in Heading-hold mode if you set the sensitivity to a negative value.  Controls mode PROFI TX Page 201...

  • Page 205: Setting Gyro Suppression

    Suppression is only effective in the Damping gyro mode, regardless of the flight phase. Before flying a model, make sure that the gyro counteracts the rotational movement of the model in Damping mode. A gyro operating in the wrong direction renders will render it uncontrollably unstable! PROFI TX Page 202...

  • Page 206: Throttle

    The idle limit is switched off in the AUTOROT flight phase, even if flight phase specific trim was or is set to 0.0%. Sometimes, it can be useful to operate the throttle directly without any restrictions. To do so, assign a switch to the CS/DTC switched function as described on PROFI TX Page 203...

    In the "climb" area (stick centre to collective pitch maximum) only 70% of possible collective pitch travel is used. This also contributes to fine control during the hover. Example 2: collective pitch curve in the CRUISE flight phase PROFI TX Page 204...

    The transmitter does not require any special maintenance or care. However, we strongly recommend that you have the transmitter checked by an authorised MULTIPLEX Service Centre at regular intervals (every 2-3 years), depending on the intensity of use. Regular functional and range checks are mandatory (see section 2.6 "Range check"...

It can be edited using the MULTIPLEX Launcher. FastResponse Reduces the transmission cycle from 21ms to 14ms. This reduces the response time for control commands.
