Transmitter - Mouse & Sim Controls

6 Channel Transmitter

Calibrating the Tx

Activating the transmitter calibration will be done by clicking one of the control buttons on the 3D transmitter model within the simulation. Simply move the sticks to their limits and operate all the switches, and then click the control button again to set and store the values.

DSMX / DSM2 USB Dongle

Your transmitter is effectively interpreted as a joystick by your PC, which allows you to control models by using any DSMX or DSM2 transmitter.

Currently the simulator is being developed and tested using a Spektrum DX6i Tx and a Hobby King USB orange dongle. which works great. Other dongles will eventually be tested as well.

Mouse Control - Ray Projection

Control panel

The control-panel can be moved, rotated and zoomed within the 3D scene. Its transparency level can be adjusted from fully opaque to completely transparent. Keys are used to reset the tilt and zoom level and to toggle the control-panel visibility.

The mouse (via ray projection) is used to operate the buttons and knobs on the control panel which set various model parameters and screen modes. Model parameters can be adjusted during flight, so there’s no need to leave the flying field. For example, you can adjust the helicopters GPS Homing controls whilst activated to watch how it affects the flight behaviour.


The transmitter can be moved around within the 3D scene just like the control-panel can.

The mouse (via ray projection) can optionally be used to operate the sticks, which works the models controls just the same as when you work the sticks with your hands. For example, you can try to fly a helicopter using your left hand to work the left stick and the mouse to control the right stick. However, doing this might be considered being silly, but it’s nothing to be ashamed of if you try it.

Various parameters and messages are displayed on the Tx screens, which can be centred by rolling the Tx control-ball which adjusts the text position.

Simulation: Recordings - View Modes

Recordings playback

Multiple models can be selected to fly playbacks at the same time, each flying a different recording. For example, you can have one helicopter flying around doing basic circuits, and another heli performing rolling circuits, whilst you the pilot are flying as usual. Or you can land and watch the other flights by selecting and changing which model you want to watch as they fly around.

Simulator view controls

Cam Catch Direction: Adjust the rate of how quickly the camera swings to keep the model in the centre of the screen. This value can be set low enough to allow the model to momentarily disappear off screen.

Cam Catch Model Normal: Adjust the rate of how quickly the camera position arrives at the pre-set zoom distance away from the model. Rotating the model has no effect on the camera's position or rotation.

Cam Catch Model Tail: Zoom adjusts the same as “…Normal” above. However, the camera is always looking down the tail. Therefore, rotating the model causes the camera’s position and rotation to change.

Model zoom level

The mouse wheel can be used to adjust the distance between the camera’s position and the model’s take-off position when using the “Pilot In The Pits” mode. In all other view modes, it’s the distance between the camera and the model’s position, whether that be the take-off position or during flight.

Transmitter view modes

Perspective 3D World: The transmitter exists within the 3D scene like any other object. For example, as you drag it from left to right you’ll see more or less of each side accordingly. The Tx can also be rotated and zoomed in relation to both its own local axis and the scenes global axis.

Perspective Front View: The transmitter exists in the scene like when in the Perspective 3D World mode. However, although rotating it changes the perspective, dragging it to a different position does not.

Orthographic View: Although you can still rotate the transmitter, it’s displayed without perspective. This does indeed look a little strange as you rotate it. However, the rotation feature has simply been left functional (just for amusement) instead of disabling it.

The actual purpose of this mode is, when the Tx is viewed without having been rotated, the ends of both the Tx sticks appear 100% square on. To emphasize that’s both sticks, which of course is impossible for a perspective mode.
