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.

GNX Side Extension Module (GNX-SEM)

+ The general idea of attaching the various NXT bases to create one complete table-top panel with one USB connection is brilliant.
+ The device looks and feels great.
+ Ability to change the number of detents for the flaps / gear sliders, or turn them into axes is typically innovative of VKB.
+ Decent number of buttons and switches.
+ Superb price.

- I would prefer if some hats / 4-ways were included to control things like radar. Or even more switches instead of the buttons would have been preferable. I imagine it was a matter of keeping the price down. But honestly I would have happily paid a bit more for more hats and switches.
- Once the detents are removed from the flaps / gear sliders, they feel a bit flimsy.
- There does not seem to be a way to move some of the buttons to a different virtual device like you can do with the axes.

As with the rest of the VKB kit, it's a quality product. Software is very solid, VKB official YouTube channel guides are top notch. You get what you pay for.

Just be mindful of compatibility with EVO Omni Throttle. It's NOT compatible with Left Hand Omni throttle when attached to the left side of it. The Omni throttle stick hits the Throttle stick on the SEM Module. It's not the technical connections or mounting (that's all fine) it's the two throttles physically colliding during movement of the Omni. It's not / wasn't well documented on their website. Images attached - there is no workaround, reconsider your setup - I went with purchasing USBC module for the SEM and have it sitting as a standalone unit.

(NOTE: I have provided this feedback to support and they may update their website site to make things more clear - this feedback is as at time of purchase March 2022)

I found the excellent videos on how to attach the SEM to my Gladiator NXT easy to understand and follow. The upgrade of the Gladiator was also easy and I can now see the SEM in the configuration utility. I have been able to configure the SEM in the modes I want- two position switch on the landing gear and a continuous axis on the flaps, but as yet I cant see the buttons in Elite. I am going to have to map them as the numbers are too high. The manual doesn't have much if anything about the SEM so I am working through trying to figure out why I can't see an axis on the config. program.
That all said- the module is very well made and designed. It all slotted together with my Gladiator NXT with a very firm fit. The bags of goodies for customisation are comprehensive. It has the feel and tactile qualities of a very high class piece of equipment, Like the difference in fell between a Casio calculator and an HP25 for those that can remember. I will be very happy once I get it to work.
