BetaFPV launches Air65 II tiny‑whoop family with three tuned 0702 motors

BetaFPV published full product pages for the Air65 II tiny-whoop family and matching "0702 Brushless Motors (2026)" aimed at the 2026 indoor racing season, pitching a claimed efficiency leap centered on a 0.10mm stator core. "The 0702 Brushless Motors (2026) feature a revolutionary 0.10mm stator core for more efficient flight and extended power," the product copy states, and the company adds that the design "minimizes magnetic losses, dramatically improving energy conversion and reducing heat generation."

The Air65 II package is offered in three tuned configurations tied to specific motor KVs and magnetic/winding processes: Champion (36000KV), Racing (30000KV), and Freestyle (25000KV. Betafpv positions each variant with distinct race roles - "The Champion (36000KV) combines maximum power and instant throttle response with durable dual-ball bearings, engineered for dominant, professional-grade racing," while "The Racing (30000KV) delivers higher RPMs and razor-sharp response for agility on technical race courses," and "The Freestyle (25000KV) prioritizes smooth control with superior low-throttle torque for fluid, cinematic flying."

The 0702 (2026) spec sheet lists a single-line mass value of 1.50g and electrical/mechanical details that racers use for tuning: Rated Voltage 4.2V (1S), Shaft Diameter ø1.0mm, Shaft Length 3.4mm, Wire Gauge 30AWG, Wire Length 35mm, Connector JST1.25 3Pin, and Mounting Hole Size "3\M1.4 EQS Ø6.6mm." Betafpv also notes "Built with upgraded materials for crash resilience, this is the definitive motor for pilots who accept no compromise" and highlights diagram assets including a "0702 Brushless Motors (2026) stator core comparison."

Retail reporting from Pyrodrone frames a related second-generation family under the names 0702 II and 0702SE II and makes additional performance claims that overlap but do not fully match Betafpv's naming and KV mapping. Pyrodrone writes that "The 0702 II 30000KV Brushless Motor is just the same high-performance motor featured in the limited-edition Air65 Champion Version." Pyrodrone also credits tile-shaped magnets and an optimized magnetic circuit with "up to 14.8% more thrust" for the 0702 II versus the original 0702, and lists family weights of 1.55g, 1.47g, and 1.45g alongside a 23000KV 0702SE II product listing and propeller recommendations such as Gemfan 1210 2-blade and Gemfan 1208 3-blade.

These public statements contain a clear conflict on the Champion motor KV and on product lineage - Betafpv lists Champion as 36000KV while Pyrodrone associates a 30000KV 0702 II with the Champion. The product naming overlap - 0702 (2026), 0702 II, and 0702SE II - is not harmonized in the manufacturer and retail excerpts, so confirmatory specification mapping is required before teams finalize ESC and PID setups or place bulk orders for the 2026 indoor season.

Racer impact is immediate: the claimed 0.1–0.2 g/W efficiency gain for the 0.10mm core and Pyrodrone's up-to-14.8% thrust boost translate directly into lap-time tradeoffs, battery endurance, and prop selection for tight indoor gates.
