BetaFPV Pavo Femto (O4)
BetaFPV
Compact 2S — buttery HD footage indoors and out
The Pavo Femto is BetaFPV's compact 75mm 2S cinewhoop for pilots who want smooth HD footage indoors and out. Its DJI O4 Lite video system keeps the complete quad at 52.2g including the air unit.
The full story
The Pavo Femto is a 75mm ducted 2S whoop that BetaFPV positions as a compact cinewhoop, built around what the company calls an 'optimized whoop duct.' The ducted frame and small footprint suit it to smooth, steady HD camera work in indoor spaces as well as outdoors.
Video comes from the DJI O4 Lite air unit, and control runs through an onboard serial 2.4GHz receiver, so there is no separate receiver to add. Complete with the O4 air unit fitted, the quad weighs 52.2g.
