BetaFPV Meteor75 Pro II O4 Wide ELRS 2.4GHz Brushless Whoop

The BetaFPV Meteor75 Pro II O4 Wide is a bind-and-fly 1S tiny whoop that pairs the DJI O4 Wide Air Unit with an onboard ELRS 2.4GHz receiver in an 80mm-wheelbase ducted frame. It suits pilots who want 4K footage from a whoop small enough for indoor flying, gaps and close-proximity freestyle, ready to bind and fly.

Key features

• DJI O4 Wide Air Unit: 159° ultra-wide field of view with 4K/60fps onboard recording.

• Canopy II damping: four shock-absorbing balls isolate the camera to cut shake and jello, and the canopy fits both the O4 and O4 Wide air units.

• Meteor75 Pro II frame: refined arm braces and duct design reduce weight and drag.

• 1102 Freestyle motors (2026): 21000KV with an upgraded rotor housing and reinforced shaft, spinning 45mm 3-blade props.

• Matrix 1S 3IN1 HD FC: flight controller, 12A Bluejay ESC and serial ELRS 2.4GHz receiver on one board, running Betaflight.
