Skill, know-how and space has always been limiting factors in bringing new enthusiasts into the wonderful world of R/C aviation, until now!

FMS has always been dedicated to enabling pilots of every skill level to enjoy the thrills of flight. Innovation then, is in our DNA.

FMS is proud to announce the 850mm Ranger. Like its sibling, the high winged airframe design with a tricycle landing gear, is very easy to fly by default. A dedicated flight control paired with a GPS sytem allows pilots to fly under beginner, intermediate and fully manual flight modes. An innovative flight perimeter fence and return to home functions provide bulletproof reliability and ease of mind-flying has never been so simple.

Flight perimeter fence function: if the aircraft is in excess of 120m away from the pilot, the aircraft will return to home automatically, with the pilot having the option of taking over the controls at anytime. Once over the home point, the aircraft will circle at a 25m altitude at roughly 40km/h.

Return to home function: in the off chance that the pilot loses orientation of the aircraft, the return to home function can be triggered and the aircraft will fly back to the home point. Like the flight perimeter function, this function does not take away the pilots' ability to control the aircraft at any time.

Once over the home point, the Ranger 850 circles until further control inputs are given.

Absolute beginners rejoice! The FMS 850mm Ranger has everything that is needed for flight! A 12A esc/receiver combo reduces the need to connect cables and a 2315-3850kv motor, 7.4V850mAh 25c battery and four 1.9g micro servos give the lightweight 305g aircraft incredible performance. The innovative 850mm Ranger is the perfect way to start earning your wings!

Sturdy, Extremely Adjustable, and Saves Huge Desk Space!
Size: 17"-49", Style: Single Arm
This WALI monitor mount is incredibly solid and handles the weight of my monitor easily without any sagging or shaking. The gas spring arm moves fluidly, making it super easy to adjust the height, angle, and tilt whenever I need to. Installation was straightforward with clear instructions, and it has freed up so much valuable desk space. Excellent build quality for a great price!

Solid Mount for a Large Monitor
Size: 17"-49", Style: Single Arm
Picked this up to mount a single 37" monitor to my adjustable desk and it’s been working great. The arm feels sturdy and holds the weight of the monitor without sagging or drifting over time. Installation was pretty straightforward and it gave me a lot more desk space compared to using the factory stand. It also moves smoothly when adjusting the monitor position or changing desk height. If you’re running a larger display on a standing desk setup, this is a solid option that feels much more substantial than some of the cheaper monitor arms out there.

Solid Budget Monitor Arm With a Few Trade‑Offs
Size: 13"-34", Style: Single Arm
The WALI Single Monitor Mount performs about the same as my VIVO single monitor arm, which was a pleasant surprise given the lower price point. Setup was straightforward, and the gas spring adjustment works well once dialed in. It holds my monitor securely and offers the full range of motion I expected—tilt, swivel, rotation, and height adjustments all function smoothly. That said, the materials and overall build quality do feel a bit cheaper compared to higher‑end arms. It’s not flimsy, but you can tell where costs were saved. If you’re willing to spend roughly 60–70% more, you can definitely get a noticeably sturdier and more refined arm. Still, for a budget option, this one delivers exactly what it promises. Pros - Works just as well as the VIVO arm in terms of functionality - Easy to install with both clamp and grommet options - Gas spring provides good adjustability once set - Excellent value for an entry‑level monitor arm Cons - Materials feel cheaper than premium alternatives - Build quality isn’t as high as more expensive arms Overall As an introductory monitor arm, this is an excellent choice. It does everything the VIVO arm can, just with slightly lower‑end materials. If you’re on a budget or setting up a simple workstation, it’s a great fit. If you want something more robust for long‑term heavy use, spending a bit more will get you a significantly more refined Monitor arm.

Sturdy and easy to assemble
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
Really impressed with this monitor mount. The build quality feels solid and sturdy, especially for the price. It holds the monitor securely with no sagging or wobble, and the adjustability makes it super easy to get the perfect position. It’s been absolutely perfect for my sim racing setup being able to move the screen exactly where I want it made a huge difference in comfort and immersion. Definitely feels like a premium product without the premium price tag.

Reliable, affordable, and user-friendly
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
The installation process was straightforward and didn’t take much time at all—even if you’re not particularly handy, it’s easy to figure out. What really stands out is how flexible the arm is. It adjusts smoothly in multiple directions, making it simple to position my monitor exactly where I want it. Whether I’m working, watching something, or multitasking, the range of motion makes a noticeable difference in comfort and productivity. It’s also very sturdy once set up. My monitor feels secure, and I haven’t experienced any sagging or instability. As a second screen mount, it integrates perfectly with my desk setup and helps keep everything organized and clutter-free.
