My current mini quad is a QAV250 with 12A ESCs, running 3S and PPM. I've updated it to Betaflight and BLHeli and it flies well but I want to build a new quad that incorporates all of the "modern" advances of the last year: smaller size, SBus, 4S, LittleBee ESCs, tri-blade props, etc.
I also want to keep it light but powerful, so 4S batteries at 1000mah, 1806 motors, no OSD. Really interested to see what kind of flight times I'll get. Unfortunately I need great video so mounting the Yi will bog it down again.
I live in Thailand so my suppliers are all in Asia. Parts list with links:
RD180 frame
Matek 5-in-1 PDB (with 5V BEC)
FrSky X4R-SB (will use Sbus)
X-Racer F303 Flight Controller (new F3 board from fpvmodel, runs ßflight)
Homemade voltage divider for flight pack telemetry
Dragonfly MC1806 2300KV (note: you need 2x CW and 2x CCW)
FVT Littlebee 20A
HQProp 4x4x3 (not the bullnose 4x4.5x3 ones)
HS1177 mini FPV cam with 2.8mm lens
FT952 Vtx
Spironet for now, want a stubbier antenna to keep a low profile for proximity flying
Xiaomi Yi (would like to replace with lighter 60fps cam of GoPro form factor if one comes out)
Misc. notes:

Misc. notes:
- No OSD (I use audio alerts for flight pack voltage and don't like the visual clutter and extra wiring)
- The X-Racer FC doesn't have Vbat input but I will attempt to make and use a homemade voltage divider for flight pack telemetry.
- I'm a bit confused about whether video filtering is necessary or not: I normally use it but see a lot of people going without it. The video system will run directly off 4S power from the PDB. If that causes too much noise I will install a filter, or try to swap it for a Vtx that provides its own power to the FPV cam (such as this but hopefully a lighter 200mw type). Unfortunately the 5V from the BEC is just short of the 6V needed for the FT952 Vtx, although enough for the 1177 cam.
- The X-Racer FC has 16MB of built-in Blackbox memory for tuning. For Cleanflight/Betaflight, it uses the SPRacing F3 hex.
