Overview

BetaFPV 0702 Brushless Motors (2026) are 1S micro whoop brushless motors featuring an industry-first 0.10mm stator core to improve efficiency and reduce heat from magnetic losses. This series is offered in three versions designed for the Air65 II whoop: Champion (36000KV), Racing (30000KV), and Freestyle (25000KV), each with specific magnetic circuit and winding designs.

Key Features

  • 0.10mm thinnest stator core tech: tested efficiency gain of 0.1–0.2 g/W compared to 0702 motors with a 0.15mm core.
  • Three precision-tuned versions for Air65 II:
    • Champion (36000KV): dual ball bearings; maximum power and responsiveness.
    • Racing (30000KV): high RPM and fast response for technical race courses.
    • Freestyle (25000KV): smooth control with strong low-throttle torque.
  • Bearing design: Champion uses dual ball bearings; Freestyle/Racing use brass bushings.
  • Durability updates: upgraded rotor materials and optimized shaft design.
