Sinew 5 - Black Widow

I wanted a light weight cruiser capable of high speeds without sacrificing efficiency or convenience. Thus, this build carries a 500mW VTX, with a full size replaceable antenna, running betaflight 3.2.3, smartaudio (through softserial), telemetry and LUA script, while still weighting 272g without the battery. PT1 and dynamic filtering was turned on and both of the gyro notches deactivated. The result is a very stable quad, with amazing dynamics, outstanding cornering, that feels very locked in and rarely shows any prop wash.

I was very excited about this frame, so wanted to do things right from the beginning. After all, I had bought the frame in preorder and had to wait a while to get it in my hands. I decided I wanted the edges of the carbon fiber painted, which turned out way better than I expected: White for one frame, green for the second one. I also wanted to keep the build as clean and light as possible, so I went ahead, depinned the receiver, and shortened the motor cables as much as possible after routing them underneath the FC. The FC was soft-mounted using M3 nylon screws and 3mm ID o-rings as spacers. The major downside to this build is that in order to access the USB port, it is necessary to unscrew one side of the cam. Not a big deal, specially considering you can tune it using LUA script, but still a little bit inconvenient. Alternatively, you could position the FC sideways, but I discarded this option since I wanted the XT60 connector position towards the back.

I don't usually use capacitors but it has been reported that these FCs behave better with them. Some pictures also show an XSR receiver and an Eachine antenna. These two were later replaced by an R-XSR and a Lumenier AXII stubby antenna to further reduce weight, improve the looks, and keep the aero lines of the quad. It will also see an upgrade to TBS crossfire and camera control added to the LED pin eventually.

Happy flying!
