Overview
BetaFPV 0802 Brushless Motors (2026) are 0802 brushless motors featuring an industry-first 0.10mm thinnest stator core tech for improved energy conversion and reduced heat. Three precision-tuned versions for the Air75 II whoop are available: Champion (28000KV), Racing (25000KV), and Freestyle (22000KV), each using specific magnetic circuit and winding designs.
Key Features
- 0.10mm thinnest stator core tech to minimize magnetic losses; stated efficiency gain: 0.10.2 g/W vs 0.15mm core 0802 motors.
- Version-specific tuning for Air75 II: Champion 28000KV, Racing 25000KV, Freestyle 22000KV.
- Bearing design by version: Champion uses dual ball bearings; Racing and Freestyle use brass bushings.
- Upgraded rotor materials and optimized shaft design for enhanced crash durability.
