5" Flowride Disc Unloading Special II

I bought two Flowride frames to make the international shipping from PiroFlip worth it, so after the compromise my first one turned into after the Asgard32 ended up being too big to fit properly I'm hoping to learn from it & make this one as tidy as I hoped the first one would be :)

The signal pads on the FC were a pain to work with (very small & pre-tinned by the factory with lead-free solder) & the Matek VTX-HV had to be connected backwards to the spare UART (eg I had to connect RX on the VTX to RX on the FC & TX on the VTX to TX on the FC, which is the exact opposite of normal UART convention). Smartport is connected to the LED strip pad with softserial (thanks to Oscar Liang for that idea).

The TattooF4S board needs a capacitor on the LiPo input, without it mine freaked out bad on any hard attitude change (flips, rolls, etc.). A 1000uF 25V cap & bumping the ESC PWM frequency from the stock 24KHz up to 48KHz completely fixed it.

Did u have to flash the vtx with any firmware when u got it or did smartaudio work out of the box? It was a while ago, but I thought I remember something about this

The Flosstyle didn't exist when I bought my Flowrides.

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..
