HobyBro KOPIS Quadcopter - Kakute F4, BLheli32, low deck, with stretch motor layout

Just received from holybro, looks like their next ready built quadcopter. Due to be released in September, but we will be doing our full review soon, on paper it seems decent :slight_smile: .

KOPIS is a high-performance ready-to-fly FPV racing drone from Holybro, Low-deck design means centralized mass and excellent handling. Stretched-X motor layout is the choice of top racers because the rear props are further from the “dirty air” coming from the front props. The result is smoother cornering and higher top speed. The FPV antenna is in a unique location behind the quad, to protect against damage. Kakute flight controller and Atlatl video transmitter give perfectly integrated control of all quadcopter systems. Tmotor AIR40/2450kv motors give a great balance of raw speed and flight time. They won’t kill your batteries either! KOPIS gives all the performance, looks, and durability of a hand-built machine, without ever having to pick up a soldering iron!
