This is my first racing build and first 6S build. I wanted a sturdy, simple, clean and reliable build that would be easy to maintain and cheap to repair.

Hardware Notes:
I knew from the start I was going to use the BrainFPV Radix. There is no reason to us any other FC right now. Since I'm using 6S and not 4S I couldn't use the same 4 in 1 ESC as my last two builds, but I had been wanting to try the Hobbywing 4 in 1 45A ESC anyway. The Hobbying plugs straight into the Radix and also has power and ground for the VTX which makes building much easier and quicker. Like my other builds I changed the resource mapping of the motors so I could turn the ESC sideways with the battery lead coming out the side.

Sitting above the FC in the stack is a mount that holds the Mach 3 VTX and R9 MM reciever so the entire stack is compact and neat. I have the VTX powered directly from the 4 in 1 ECS plug and the reciever is powered from the VTX which made the build process pretty simple and easy. The VTX and camera are both wired up to the Radix on the same side so there isn't a lot of extra wire running across the build. On the VTX I'm running the stubby axii so I never have to worry about a bent antenna.

For the camera I wanted to try a lense with a wider FOV since I was going to be running a higher camera tilt and I thought it might be easier to see when navigating around a track. So I decided to go with the Runcam Robin and a 1.8mm lense which I don't regret at all after flying it around. I was worried about trying to land with the higher camera tilt, but with the wider FOV I can hover in slowly to land and still see the ground. The Runcam Robin also doesn't have a lot of extra features that I never used anyway making a lot cheaper than other cameras so if I do break it, it will be cheaper to replace and I don't have to sacrifice build quality or performance.

For the frame I wanted one that had 3D printed mounts for a gopro and the antennas, compact for racing and had the option for 6 inch arms so I could try a hybrid setup with 6 inch back arms. The XILO Phreak from GetFPV checked all those boxes. Its also pretty cheap. I don't plan on running the gopro for racing but I still wanted one so I had the option. The hybrid arms fly really well.

The motors I also wanted to go on the cheaper end since those are probably going to get bashed up more than anything. Luckily the EMAX ECO motors seem pretty solid for the price so I don't feel like I ended up with a "cheap" motor. I really like HQ props so I decided to try their 5x5x3 props and they feel pretty smooth and fast. I really like using the PCB's on 4 in 1 builds so this time I decided to try them with LEDS on them. I've never tried LEDS since it seemed like the extra work wasn't worth it, but with these I don't have to do anything extra.

Overall I'm really happy the way the build turned out and the way it flys. I feel like I hit all the goals I had for this build.

Software Notes:
I'm running Betaflight 4.0.2 and since I'm running 6S for the first time I'm using the 6S racer community presets for Betaflight. I think it needs a little tuning but the community presets performed pretty well. Also, launch control is pretty cool.

On the ESC I'm running Blheli_32 on DShot 1200, with motor timing is set to AUTO and motor frequency set the 48hz.
