The VKB Gladiator is in a totally different league to anything made by Logitech, Thrustmaster or Turtle Beach. It is the entry-level to high-end controllers, and makes the others mentioned look like the cheap plastic toys they are in comparison.
Design and build quality, materials and electrics are all far superior to TM,TB and Logitech products. The standard Gladiator NXT Evo has everything you need to fly, and you can add modules for throttles, extra controls and autopilot as time & funds allow. These can mount separately or on the side of the Gladiator base, whatever you prefer.
The EU store in the NL services UK buyers, and once in stock your order will usually be with you inside a week. When you enter a UK address at the checkout, the site will automatically deduct EU VAT. If your order is over £135 and therefore eligible for UK VAT on import, the courier (UPS) will contact you prior to delivery, and you pay UK VAT and any import / customs charges to them. Sometimes you might get lucky, but not always.
The Gladiator is currently on back order and awaiting stock, some Gunfighter sticks are available in stock but they are pricier (although very definitely worth it).
I had a Gladiator NXT Evo that did over 1,000 flying hours in MSFS, and it looked and felt exactly the same at the end as it did on the day when I first unboxed it. I had zero problems with it, and the configuration and calibration software is superb.
I’ve since traded up to a Gunfighter / MCGU stick with the S-TECS throttle, T-rudders and all the side modules, and I would buy from VKB again in a second. The flying feel, performance and build quality of their products are just superb, and if you have any issues or questions the company is responsive. There is also loads of help and advice available on their forum.
