Introducing the Armattan Bobcat. It's no secret that 4 inch models are making a comeback on the FPV scene. With the right power plant and with new technology available from Caddx and DJI, it is now possible to put together a lightweight 4 inch quad capable of very good endurance and HD recording. The Bobcat is Armattan's take on what they think is the best solution for this type of application. 

Armattan had to step outside of their comfort zone for this design. Their designs are never meant to be the lightest thing on the market. Until now they focused a lot on freestyle designs. Armattan offers a lifetime warranty and that means their models need to be able to take a beating.

After many designs and prototypes, the Armattan Beaver Frame 5" Quadcopter Frame Kit is here! The Armattan Beaver features a strong carbon frame with thicker arms than previous versions which makes it the strongest to date. This frame focuses on noise reduction, easy maintenance,  and versatility for use with a variety of electronics. With a weight of 126g, this frame is lighter than previous Armattan frames.
