Best DJI HD Sub 250g FPV Drone? Putting motor/propeller tests results into practice.

I recently completed and tested a 3.5" build using a motor and propeller combination proven to be extremely performant and efficient in bench tests we've gone over together. The goal was to build a light weight full featured HD build that is both efficient, and performant, allowing for an extremely high thrust to weight ratio with reasonable battery sag and flight times. This video goes over that build, the data behind it, performance expectations, and basic flight test data. ------------------------ Relevant Test Videos 3" vs 3.5" on 1404 (Incl 3.5" comparative propeller tests):    • 3.5" vs 3" Propeller Performance and Effic...   3" vs 3.5" on 1404 (Incl 3.5" comparative propeller tests) Part 2:    • 3" vs 3.5" Propeller Testing PART 2,  with...   1404 vs 1408 on 3.5":    • 1404 vs 1408 on 3.5" Propellers - Full Com...   1404 comparative motor testing:    • Recursion Labs - 1404 Motor Performance Te...   ---------------------- Build Propulsion Main Data Charts Thrust to Motor Utilization: https://i.imgur.com/pu2KzNG.png Efficiency by Motor Utilization: https://i.imgur.com/FPHusm8.png Thrust to Watts: https://i.imgur.com/3RQSiGo.png ----------------------- Build Components Frame: Happymodel Crux35 - https://www.banggood.com/custlink/DDG...
