How light can a brushless whoop be, and what would it take to build one? Let's find out! Build details, links, and PID tune below...

Parts:
- BetaFPV F4 1S AIO FC v2: bit.ly/2m2JX9e
- BWHOOP65 Frame: amzn.to/33EapH2
- RacerStar 0603 16,000KV motor: bit.ly/2VPraMD
- Better motors you might want instead: bit.ly/2VMKJVX
- Gemfan 31mm 4-blade Props: bit.ly/2nSvjmt
- The camera/vtx I actually used (not really recommended): bit.ly/2nTWvBl
- The newer camera I mentioned (might be better?): bit.ly/35H4KSg
- RENY M1.4 4mm screws: bit.ly/2P0JOzT
- FrSky antennas (for making custom monopole fpv antennas): amzn.to/2qlAf47
- The real PH2 connector (90-degree version): bit.ly/2Jcu4Gj
