GNX Side Extension Module (GNX-SEM)

The GNX Side Extension Module adds a new level of realism to the passionate flight and space pilot.

While the GNX-SEM was designed with General Aviation pilots in mind, the module is highly configurable to suit any flight and space sim cockpit.

The SEM can be attached side-by-side to:

  • Gladiator NXT EVO Standard or Premium controller base (from either side)
  • SEM modules (max number of SEM modules in system – 4x)
  • THQ modules (max number of THQ modules in system – 4x)
  • Gladiator EVO Omni Throttle, but only on the opposite side of the throttle’s ‘elbow’. For example, a left-hand throttle only allows attachment on the right hand side. To overcome this limitation a USB Controller can be used which then allows the SEM to be connected to the PC and therefore placed independently of the controller

Up to 4 SEM modules can be accommodated in your cockpit.


  • 1 Rotary switch
  • 2 Multi-function axis
  • 2 K-switches w/ central push button
  • 7 Push buttons
  • 8 Programmable, dual colour LEDs
  • Provides either a total of 24 logical buttons, or 17 logical buttons and 2 analogue axis (based on configuration)

Excellent add on ! But instructions unclear

Getting the important things out of the way why it's 4 out 5 and not out of 5 out 5. *Buyers be aware *

The connection between some joysticks is different than shown in the instructions video. No instructions were in the box to state the proper way to connect to the Omni throttle. Some Omni throtles do not have a 3 pin and only have a 4 pin.

The box come with a 4 pin to 3 pin and a 3pin to 3pin cable, But if you use the 4pin cable (as one would assume you would need to do, it won't work. It requires the 3 pin cable to 3 pin to plugged into a 4 pin connect of the joystick leaving 1 pin exposed. Making sure the pin exposed still is the right one. I had about 5 emails back and forth with support (Which helped me out at the end) but still wasted a good 3 - 4 hours going back and forth. Please VKB update your instructions or include a little print out to make sure people are aware of this.

The module itself is excellent. Super configurable, tactile buttons, good packaging and extras. Like the stickers for changing names and little extra knobs. Good support as well!

Just wish it had a longer cable for the connection itself so you can place it around your desk without needing to be on the left or right of the joystick. I know USB module is available but I don't want another thing plugging in to my limited number of usb ports in my computer. Mind you this is a nitpick.

Just awesome

Adding this to my gladiator joystick makes the flying experience so much more fun. I have also bought the THQ since this purchase. The GNX has proper well designed switches and buttons. Like all this VKB stuff it is all highly configurable and built to last. I also have the rudder pedals that I could not live without. The support is also amazing.

Hi Gary,

Thank you for the 5 star rating and the positive review.
We also appreciate your nice comment about our customer support.

Instructions need updating

The VKB channel installation instruction video needs to be updated to include the Gladiator EVO. It includes a 3-4 pin cable and a 4-4 pin cable, but the video only mentions the 3-4 being plugged into the 3 pin socket port on the Gladiator. The EVO only has one 4 pin socket. Clarification needed. Will update review when its sorted & I get a chance to use it.
