Introducing the Armattan Beaver. This one is three years coming. It's the longest we have ever spent working on a frame. Well, to be frank, the 2020 situation made us put a pause on development for a little while. Nonetheless, this design has taken a very long time and it has gone through many more iterations and prototypes than any other Armattan frame before. The best way to describe what the Beaver is about is probably to look at our design goals.
Strength: This frame needs to be strong enough to be worthy of lifetime warranty. The frames need to be able to take a beating. Thicker arms than any other previous frame, as well as thoughtful crash-protection provisions make the Beaver our strongest design to date.
Noise: Three or four years ago, blackbox readings and tuning were not much of a thing. Things have changed a lot since then. The Beaver is our first five inch design for which a big emphasis on reducing noise reaching the flight controller was devised. This is by far the stiffest frame we have ever made. The top plate is also using additional anchoring points adding stiffness throughout the entire chassis. Easier to tune for newcomers and more satisfying for folks who strive to have the perfect tune.
Modern provisions: As always, we try to adapt to new electronics on the market as to provide good building options with a variety of controllers, video links and RC links. The Beaver is our most versatile model to date. Cameras have gotten so small. Large cages seen on our previous models are no longer needed. This model has the smallest and lightest camera cage we have ever used on a design for five inch propellers. This allowed us to better balance the frame strength and weight distribution. This takes us to our next goal.
Weight: Stiffer, stronger, smarter, NOT heavier. 126g. The weight is on par or less than our previous 5 inch frames.
Ease of maintenance: Only one bolt needs to be removed to replace an arm at the field. As for the rest of the build, there's nothing complicated or overly complex to work on. It's a breeze to work on.
Looks: Finally, and always last on the list of priorities, aesthetics. We try to make good looking frames, but function comes before fashion, always. The Beaver is the best frame we've ever made and it looks the part. We chose the classic orange look, reminiscent to the iconic Armattan Chameleon. The Beaver is a completely different beast, however. It's a critical evolution that encompasses our design goals, five years later, in 2022.
Price Point: The Beaver is priced better than all of our previous high-end, freestyle frames. We're checking a lot of boxes here...
As always, a massive thank you goes to Jason Hay, our CAD guru for the fantastic help once again.
Also a big thank you to Brain 3D for their help with designing optional 3D printed parts. They have them all. Check them out here.
