I thought I'd jump on the bandwagon and build a medium range quad using my favorite 6" frame, the Flynocerus Aether. The flight stack is composed of the Hobbywing X-Rotor Micro 45A 4 in 1 ESC, BrainFPV Radix flight controller and the HGLRC VTX/DVR.
The motors I'll be using are the amazing new BrotherHobby Speed Shield 2207.5 1750 kv motors. They're noticeably lighter and smaller than comparable motors, and the Marvel Comics Captain America theme is very cool.
I was hoping this was going to be a quick build as this is my second Aether build, but I guess this is where the don't come into play lol. When doing a new build, it's all about the planning, research on parts compatibility and mocking up to make sure everything fits together properly.
After 4 or 5 cups of coffee, and with great haste, I proceeded to mount the BH motors and HW ESC and solder up the motor wires. About 2 minutes after I was done, I realized that this was a no go and that the motor wires were outside the frame and just begging to be torn off the board on the first rough landing. Back to the drawing board.
No big deal right? Just reroute the wires from the outside to the inside if the standoffs and resolder them back on. No, the motor wires are now a 1/4" too short! Luckily I had a few packs of RaceWire that I bought on a whim. I'm not a big fan of RaceWire as the pads are soooo close together, but they certainly saved my ass on this build.
Got the stack all soldered up. I like to put everything in place and figure out the length of wiring required. Then I remove it and solder it up on the bench. In this setup, 8 of the 10 wires on the Hobbywing ESC goes to the Radix flight controller for motor signals, 5v power, voltage and current sensor. The other 2 wires are 10v out which I'm using to power the VTX. The receiver (I have the FRSky R9 module installed on my Taranis so I'm using the R9M Mini receiver) is connected to the 5v supply on the Radix. The 2 unconnected cables are for the camera and GPS module as I'll be enabling GPS Rescue feature in Betaflight. All that's left to do is install the Hellgate buzzer. Easy peazy.
Installed back on the frame, one thing that's sometimes overlooked in a build is proper spacing between the boards. You want separation so that you don't incur any shorts, but you also don't want them so far apart that you run out of room in a tight build. This one turned out just right with 3-4 mm clearance and still lots of room between the ESC and frame for the battery strap
