This is my loved rooster, a freestyle dedicated quad, fun both to build and to fly.

Build took a couple of hours, all in all, it was a simple build. I found only a couple of problems.

The press nuts of this frame are really hard to install, and I had to forced them with the risk of breaking up the frame, infact I had some small crack.
The other problem was the position of the xt60 cable: after a couple of tries, I decided to pass it under the frame and get it out of the front, the only way for plugging my batteries without forcing connector and cable.

Frame is not really spacious, especially in height: on the back I had to fit like a puzzle the receiver, the vtx and the buzzer. But I like because it is compact and finally is not very heavy for a 220 quad: 704 gr including battery and gopro.

Flight controller has integrated soft mount inside mounting holes, so I gain a couple of millimeters in height.
Its pads are very close, so be careful when soldering. Pads for esc's are on the 4 angles, for a cleaner build.

Pdb has 2 regulated pads for 5 and 12 V out and I can feed cam and vtx without passing through FC with 12 V. Even if there are the appropriate pads on FC I prefer to stress as little as possible the controller.

The thing I prefeer of this quad is the interaction with Betaflight interface without using a PC: Fortini F4 OSD flight controller has Betaflight integrated, but also Stealth Race LR vtx is settable directly from my Taranis QX7, using smartAudio pin for telemetry and after installing some LUA scripts in the radio. Vtx has also microphone integrated.

Motors are really solid: after some crashes they do not yet have yokes. They are only CW.

In flight is really powerful but also stable and snappy. I had to spend some time to tune PID and regulate rate profiles to get a good performance.
It's not perfect yet I still have to solve some small oscillation on acceleration, but in general I'm very happy of this quad.
