My first ever build, it's pretty decent. Inspired by KababFPV's and The RCAddict's cheapest quad worth building.

Build video I used, make sure to use in conjunction with the FC schematics.
This is how I set up Betaflight.

Notes & What I'd do Differently:

1. The batteries for the quad can be used for the goggles I chose, so I just rotate all batteries around.
2. If you've got some extra cash to spend KababFPV now recommends the iFlight Xing-E 2306 motors for a few dollars more.
3. Good props are: Gemfan 51433, Nazgul 5140, DAL Nepal N1.
4. Getting a nylon standoff kit with shorter sizes is better. The one I purchased has too many useless long standoffs. I'd get this.
5. Get the ISDT Q6 Pro and Lantian power supply bundle instead.
