HummingBird F4 1S Brushless BetaFlight Flight Controller

HummingBird F4 1S whoop brushless flight controller is the first brushless flight controller made by HummingBird R&D team. It is sharing some of the NewBeeDrone technology such is NBD OSD Chips. Although NewBeeDrone declaers this Flight controller as the lightest brushless whoop controller (3.77g with power lead and FrSky receiver), it is probably not lighter than BetaFPV F4 1S V2 flight controller (weights 2.69g without power lead, but with FrSky receiver) or Crazybee F4 Lite 1S Flight Controller (4.5g with power lead, FrSky receiver and VTX)

Very interesting flight controller from NewBeeDrone.
