BETAFPV Air75 Brushless Whoop 1S 75mm — 5IN1 G473 FC | ELRS 2.4G | 0802SE 23000KV | C03 Camera | BNF
The Lightest 75mm Whoop Ever Built — And It Actually Rips.
Meet the BETAFPV Air75: a 75mm brushless whoop that weighs just 21 grams fully assembled — no battery. That's not a typo. BETAFPV completely rethought the platform from the ground up, and the result is the most capable ultralight 1S indoor/outdoor whoop available right now.
🧠 Air Brushless Flight Controller (5IN1) — G473 Processor The Air75 runs BETAFPV's new Air Brushless FC, the first 1S flight controller to use the STM32G473 processor — a 55% computing speed increase over the F411 found in the older Meteor75. On a single 3.6g board you get: FC + ESC + OSD + onboard 5.8G VTX (25–400mW adjustable) + Serial ELRS 2.4G receiver — fully integrated, nothing external to wire. The gyroscope is the industry-standard ICM42688P, running at up to 8K sample rate, with a 16MB black box onboard. Multiple UART ports mean you're not locked into any particular setup.
📡 Built-In ELRS 2.4G — ELRS V3 Firmware The 5IN1 version ships with a serial ELRS 2.4G receiver already soldered in and running ELRS V3 firmware over CRSF protocol. Bind it to any ELRS-compatible transmitter (LiteRadio 3, RadioMaster, BetaFPV LR, etc.), and you have a long-range, low-latency link in a 21g package. No external RX module. No extra wires. Just bind and fly.
📺 5.8G VTX — 25mW to 400mW The onboard VTX is adjustable from 25mW (indoor/proximity) up to 400mW — serious range for a whoop of this size. Pair it with any analog FPV goggles (Eachine, Fatshark, SkyZone, etc.) and you're good to go.
⚙️ Propulsion: 0802SE 23000KV + Gemfan 40mm 2-Blade Props BETAFPV's 0802SE motors at 23000KV deliver explosive throttle response and high RPM punch that makes this drone feel genuinely fast indoors. The Gemfan 40mm 2-blade propellers are tuned for efficiency and crisp control — larger pitch tip for quick power delivery and immediate steering feedback.
📷 C03 FPV Camera — 720p, 1.45g The micro C03 camera weighs just 1.45 grams and delivers clean, sharp analog video. The Air Canopy supports camera angle adjustment from 25° to 50°, letting you dial in your preferred freestyle or racing angle. The redesigned canopy flexes on impact instead of snapping, dramatically reducing crash breakage.
🪶 Air75 Frame — 4.45g, Sub-20g Build The Air75 frame was redesigned from the Meteor75 platform — shaved down from 5.68g to 4.45g without sacrificing rigidity. New motor mounting slots, lower profile, and available in 8 colors. Combined with the Air Canopy and 5IN1 board, the whole assembled drone comes in under 21g dry.
🔋 Battery: BT2.0 Connector | LAVA 1S 450mAh 75C (sold separately) The Air75 uses the BT2.0 connector — lower resistance than PH2.0, meaning less voltage sag under load and more consistent punch from takeoff to landing. BETAFPV's LAVA 1S 450mAh 75C battery (with Z-Folding Process for tighter center-of-gravity) is the recommended pack and gets you up to 6.5 minutes of flight time. Battery is sold separately — see our store for LAVA battery listings.
