It's not a coincidence that you need a different setup for different styles of flying. When you fly freestyle, you need an HD camera and ability to survive a hard crash. This is why freestyle quadcopters can weight between 400 and 500g before battery and HD camera. But when you want to race, it's a dead end. Sure, you will fly through the gates, but extra weight will make everything complicated.
For racing, you need something lighter. Around 300g or less without battery. My latest design is based on Race Day Quads Mach 1 frame and here is a specification:
As a result, Mach 1 was born:
- Frame: Race Day Quad Mach 1
- Motors: EMAX RS2 2306 2400KV – the next generation of the famous EMAX red bottoms. Even more oomph than before and quite nice windings
- Flight controller: Holybro Kakute F4 v2 – very thought through design. Putting all connectors on one side make soldering quite nice and easy. I like this flight controller very much!
- ESC: 4-in-1 Holybro Tekko32 35A – connecting to Kakute F4 v2 is super simple. Just a one ribbon wire and everything works out of the box. BLHeli32 and ESC telemetry are a nice touch
- Camera: RunCam Micro Swift 3 – to be honest, I slightly regret I got mark 3 of this camera. I prefer OSD joystick than another UART somehow. Oh well, good thing that Kakute F4 had an extra UART to spare
- VTX: Eachine TX805 – silly cheap SmartAudio compatible video transmitter. Maybe 800mW is a lie, but it is surprisingly good and I'm quite happy with it. Here is my review of Eachine TX805
- 5.8GHz antenna: RealAcc UXII – I do not like them very much, but this was the only stubby antenna I had on hand so I just used it
- RX: FrSky R-XSR – very small full-range FrSky receiver. Period
