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

Also, what made you choose this frame over the flosstyle? I'm on the fence about which one ill get

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

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
