Wiki / Controller / USB Interface

USB Interface

AeroSIMRC is supplied with an USB Interface which is used to connect your Radio Transmitter to the computer.
The aircraft are controlled in the simulator with your own transmitter for the best training experience.

Red LED inside the USB case

The red LED inside the USB case provides the following information:

Red LED Meaning
ON Normal operation. The USB interface is receiving a signal from the transmitter.

The USB interface is NOT receiving any signal.

For example, when the transmitter is:

  • Not powered on.
  • Not connected.
  • Not outputting any signal.
  • Not configured correctly.
Flashes 4 times The USB interface has just powered up (when plugged in a USB port).
More information
Flashing The USB interface is in a special mode for entering license codes. Please, follow the instructions on the screen to exit this mode.

Wiki / Controller / Transmitter Calibration

Transmitter Calibration

Purpose of 'Transmitter Calibration'

The simulator needs to learn the end positions and neutral positions of each stick in your transmitter.

Transmitter Calibration consists in moving each control (sticks, switches and knobs), while the simulator learns their neutral and their end positions.

Calibration Assistant

Follow the instructions provided in the Calibration Assistant in the simulator.

Go to Top Menu / Controller / Configuration / Config 'A'
and click the Configure and Calibrate TX button.


The transmitter should not transmit radio signals while you use it for simulation (this extends battery time, and prevents damage by heat building up)

Manually check the transmitter Calibration

  1. Move the sticks to the ends: the numbers should reach -100 and 100.
  2. Leave the sticks at the neutral position: the numbers should read 0.

Wiki / Controller / Channel Configuration

Channel Configuration

What is 'Channel Configuration'?

The Channel Configuration tells the simulator which stick, switch, or knob in your transmitter, controls each function in the simulated aircraft (e.g. roll, pitch, landing gear, flight mode, camera pan/tilt, etc.)

How to do the Configuration?

  1. The configuration screen is accesed from Top Menu / Controller / Configuration / Config 'A' or 'B'
  2. During the Calibration Assistant, the simulator automatically learnt which channels operate the four basic controls:
    • Roll
    • Pitch
    • Thottle
    • Yaw
  3. Hence, after the Assistant is completed, you have to configure the rest of the functions you want to operate from your transmitter

Configuration Screen

Channel Feedback Display

The bars show each channel position as received from the Transmitter

Move any stick, switch or knob in your transmitter and see which channel number it corresponds to.

Channel positions

Channel positions as received from the Transmitter

Mapping Channels to Functions

Select the functions to be operated from your Transmitter

Tick with the mouse the corresponding round buttons to assign the Transmitter Channels to the desired model functions.

The check box on the left Enables/Disables each function.

The 'REV' check box , reverses the direction of the channel

Channel assignment


  • Channel 6 operates Flaps
  • Channel 5 operates Retractable Landing Gear
  • Channel 2 operates Wheel Brakes
  • Channels 4 and 6 operate FPV Camera Pan and Tilt
  • Channel 7 operates ALT Hold and Camera Stabilization (in multirotors)

Channel positions

Each channel can be mapped to several functions.

For instance, Brakes and Flaps can be assigned to the same channel.
However, this could be confusing on models with both Flaps and Brakes.

Watch the Mapping Result

Operate the Transmitter sticks, pots and switches, and verify the result immediately on the screen:

Control feedback

See the results immediately on the screen

Transmitter Mode

The Mode of your Transmitter is automatically identified by the Calibration Assistant

The Transmitter Mode number determines the function of each transmitter stick (aileron, elevator, etc.)

Mode Left Stick Right Stick
1 Rudder & Elevator Aileron & Throttle
2 Rudder & Throttle Aileron & Elevator
3 Aileron & Elevator Rudder & Throttle
4 Aileron & Throttle Rudder & Elevator

Config slots 'A' and 'B'

There are two memory slots (Config 'A' and Config 'B') to store calibration and configuration data for two different transmitters or setups.

How to check the Channel Configuration?

  1. Go to Top Menu / Controller / Configuration / Config 'A' or 'B'
  2. Move the sticks in your transmitter and check that the motion of the sticks are the same as on the screen (e.g. left stick also moves left on the screen).
  3. Check that the switches and knobs operate the desired function.
Wiki / Controller / Controls



The aircraft in the simulator can be controlled with:

Keyboard shortcuts

Most functions can also be operated from the keyboard and mouse.
The key assigned to each function is displayed when hovering the mouse over it.

Wiki / Controller / Keys



All functions in AeroSIMRC can be activated from the computer keyboard. For instance, to restore the model to the initial position on the runway, press Space.

The key assignments can be changed from Main Menu / Controls / Define Keys

Key assignment panel

Wiki / Controller / Mouse with TX

Mouse with TX

You can control the Mouse cursor with the Transmitter sticks

You can operate all simulator functions from your transmitter. No mouse, no keyboard needed.

Select a Transmitter channel to activate the Mouse Control at the channel configuration screen.

This is the cursor displayed when the mouse emulation is activated:
