Colombian Carbon Wheelman Stretch X 5". I got a good deal on some EMAX parts and based the build around them. Went with the Betaflight board because of the easy build, OSD, and plenty of UARTs. SBUS taking up one UART, Smartport telemetry and TBS Unify smartaudio take the other two.

I built it upside-down because of the PDB on the bottom of the Betaflight board. I soldered the receiver to the bottom as well, since it's being shoved under the FC. After soldering the receiver on, I soldered the ESCs upside-down and applied waterproofing to the whole receiver and bottom of everything else, before flipping everything over and finishing the topside. Soldered a VTX and camera harness, mounted and soldered motors, and added waterproofing to the topside of the FC/ESCs and entire VTX.

This is my first time waterproofing. The silicone conformal coating was easy to apply, simply painting it on, avoiding the buttons and ports. I did multiple coats with at least 30minutes dry time between coats. Weight as seen in the final glamour shots is 307grams dry and 499 with the Tattu R-Line 1550 95c.
