They're built around an \u003cstrong\u003eindustry-first 0.10mm stator core\u003c\/strong\u003e. That ultra-thin core cuts magnetic losses and heat, and in BETAFPV's testing it delivers a \u003cstrong\u003e0.1–0.2g\/W efficiency gain\u003c\/strong\u003e over 0702 motors with the older 0.15mm core.

Both are 1.0mm shaft props that match these motors.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhat does it fit?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nThey're designed for the Air65 II (both the Air65 II and Air65 Champion frames) with the Matrix 1S 5IN1 II flight controller. They use a 3×M1.4 mount on a Ø6.6mm pattern, so check that your frame matches before using them elsewhere.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eDo I need to solder them?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nNo. Each motor has a JST1.25 3-pin connector on 35mm leads, so they plug straight into a matching board. Racers who want to shave weight can cut off the connector and solder the leads directly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhat's the big deal about the 0.10mm stator core?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nA thinner core wastes less energy as heat. That means the motor runs cooler and turns more of your battery into thrust, a gain BETAFPV measured at 0.1–0.2g per watt compared with its previous 0.15mm core.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eHow many motors come in a pack?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nFour, plus 12 M1.4×3 screws.
