BetaFPV 0702 Brushless Motor Set (2026) 0.10mm Stator Core, 1S, 25000/30000/36000KV

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 0.10.2 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.

Choose the 0702 version that matches your build goalChampion for maximum punch, Racing for fast response, or Freestyle for smooth low-throttle control.

Compact 0702 sizing with a 1.0mm shaft and 35mm lead makes fitment straightforward on 1S micro whoop frames.

The 0.10mm stator core is built to improve efficiency and help reduce heat from magnetic losses.

Efficiency gains are most noticeable through the mid-throttle range where micro whoops spend much of their flight time.

Hardware differs by versiondual ball bearings on Champion, and brass bushings on Racing and Freestyle.

Upgraded rotor materials and an optimized shaft design are intended to improve long-term durability.

Performance tables provide a quick way to compare current draw, thrust, and efficiency between KV options.
