From VKB NA's FAQ page:
How to Flash/Reset/Calibrate your Gladiator w/ MCG grip
To get started, follow these initial steps:
Download the latest (by date) VKBdevCfg-C app – (
http://ftp.vkb-sim.pro/Programms/) and extract it to any folder you like.
Download the latest (by date) ZBootloader-C app – (
http://ftp.vkb-sim.pro/Programms/) and extract it into the same folder as above.
Download the latest (by date) firmware for Gladiator (
http://ftp.vkb-sim.pro/Firmware/Gladiator) and extract the firmware (*.vkb) for your MCG or MCG PRO respectively, and put it into the same folder where your VKBdevCfg app already is.
If you have created a custom profile (i.e., different, or custom button assignment) be sure to save it first via VKBdevCfg > Action > Save; after flashing/resetting/calibrating, you can load your custom profile again via VKBdevCfg > Action > Load.
Ensure that your new MCG grip is installed on the Gunfighter base, and that it’s seated correctly.
From here on out, there are three basic steps involved in the overall process:
Flash your Gladiator with the new firmware.
Reset your Gladiator to default.
Calibrate your Gladiator.
I. Flash your Gladiator with the new firmware:
Launch VKBdevCfg-C (Note: It is highly recommended to right-click on the VKBdevCfg app and select ‘Run as Administrator’).
In the top panel, click on the “VKBsim Gladiator…” name to select it.
From the Tools tab, click on the “Bootloader” icon; this should close VKBdevCfg and automatically start ZBootloader-C (if you have it in the same folder).
Point ZBootloader-C to the extracted *.vkb file and update the firmware of your Gladiator by clicking “Flash It”.
The device will restart with the new firmware installed.
Q: Why do I have to flash?
A: You will have to flash your your joystick base to make your new MCG work with it. Simply removing your current grip and installing your new MCG will not magically make the base understand what just happened; you need to tell the base (via firmware update) that there’s a new grip in town!
II. After Flashing, you need to Reset your Gladiator to default:
Launch VKBdevCfg-C (Remember: It is highly recommended to right-click on the VKBdevCfg app and select ‘Run as Administrator’).
In the top panel, click on the “VKBsim Gladiator…” name to select it.
From the Tools tab, click on the “Default” button in the top-left corner.
The device will restart with factory default settings.
III. After resetting, you need to Calibrate your Gladiator:
The goal is to be able to capture all available axes in the calibration procedure: the Gladiator’s throttle, pitch and roll axes, as well as the ministicks, trigger and brake axes in the MCG/MCG PRO.
Don’t use the MS Windows calibration utility! Use VKBdevCfg instead.
Flip the foldable trigger to the “up” position, and then squeeze the trigger fully, and then let go of it to determine its middle position (MCG PRO only).
Launch VKBdevCfg-C (Rember: It is highly recommended to right-click on the VKBdevCfg app and select ‘Run as Administrator’).
In the top panel, click on the “VKBsim Gladiator…” name to select it.
From the Tools tab, click the ‘Start Calibr’ button (Hint: switch to the Test > Axes1 tab to observe your calibration action).
Move the grip through its full range (pitch and roll axes), move the throttle fully back and forth.
On the grip, move the MASTER MODE (РЕЖИМ КБО) ministick through its full range (Hint: you might have to do a long-press on the ministick push button in order to enable relative axis mode first; otherwise, the ministick defaults to button mode and thus won’t calibrate).
Move the GATE CONT (УПРАВ СТРОБ) ministick through its full range.
Squeeze the MCG BRAKE lever fully and let go of it.
Move the foldable trigger to the “up” position, squeeze it, and then let go of it – this moves it through its full range (MCG PRO only).
If you have VKB T-Rudders connected to the Gladiator’s base: move the T-Rudder axis through its full range as well.
Click the ‘End Calibr’ button; the Gladiator will restart.
Done; calibration information is stored within the Gladiator’s MCU.
Reminder: Don’t forget to load your custom profile again via VKBdevCfg > Action > Load.
