5" Flowride Disc Unloading Special II

By cjdavies on Apr 14, 2018

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.

Like any other 2206, but without having to worry about mud!

Nov 16, 2018

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...
