0702 vs 0802 vs 1102 Motors (2026): 1S Whoop Motor Guide

October 1, 2026 · CSKYUAV Technical Team

If you are building or upgrading a 1S micro whoop in 2026, the short answer is this: pick the 0702 Brushless Motors (2026) for a 65mm Air65 II, the 0802 Brushless Motors (2026) for a 75mm Air75 II, and the 1102 Brushless Motors (2026) for a Meteor75 Pro II. All three families run on a single 1S lithium cell, share the same 3×M1.4 mounting pattern, and are precision-tuned for the frames they ship with. The differences sit in KV ratings, power output and weight: the 0702 tops out at 27.53 W and 1.59 g, the 0802 at 34.3 W and 1.95 g, and the 1102 at 35 W and 2.85 g. This guide compares every published specification from the official product pages, explains the new 0.10mm stator core, and helps you choose the right Champion, Racing or Freestyle version for your flying style.

What Do 0702, 0802 and 1102 Actually Mean?

Micro whoop motor names follow a simple convention: the first two digits are the stator diameter and the second two are the stator height, both in millimetres. A 0702 motor has a 7 mm stator diameter and 2 mm height; an 0802 is 8 mm across; and an 1102 is 11 mm with a 2 mm height. A larger stator moves more magnetic flux, which generally means more power and torque at the cost of weight.

That is exactly what the published numbers show. The 0702 (2026) weighs 1.59 g in its Champion version and 1.50 g in Racing and Freestyle versions. The 0802 (2026) steps up to 1.95 g and 1.88 g. The 1102 (2026) is the heavyweight of the trio at 2.85 g, but it also delivers the highest maximum power at 35 W with 9.2 A of maximum current. In other words, the naming convention directly predicts the performance hierarchy.

The table below collects every specification published on the official product pages for the 2026 motor generation. All three families share the same JST1.25 3-pin connector, 3×M1.4 mounting holes with a 6.6 mm circle, and a 4.2 V (1S) rated voltage.

Three numeric jumps stand out. Maximum power rises from 15.01 W (0702 Freestyle) to 22.73 W (0802 Freestyle) to 35 W (1102) — more than a doubling across the range. Maximum current climbs from 3.86 A to 5.90 A to 9.2 A. And KV ratings drop as stator size grows, from up to 36000 KV on the 0702 down to 21000 KV on the 1102, because larger stators do not need to spin as fast to produce thrust.

Which Motor Matches Your Whoop Frame?

BETAFPV designed each 2026 motor family around a specific whoop, and the official recommended-parts lists make the pairing unambiguous. The 0702 (2026) is tuned for the Air65 II Brushless Whoop with GF 1207 or GF 1219S props and the Matrix 1S 5IN1 II flight controller. The 0802 (2026) pairs with the Air75 II Brushless Whoop using GF 1614 props. The 1102 (2026) is built for the Meteor75 Pro II O4 Brushless Whoop with Gemfan 1811 3-blade props.

The official lists also give some cross-compatibility latitude. The 0802 page recommends the Meteor65 Pro frame alongside the Air75 II frame, and the 1102 page lists both the Meteor75 Pro II frame and the original Meteor75 Pro frame, with the Matrix 1S 3IN1/4IN1, 5IN1 and 5IN1 II stacks all supported. Battery pairing scales with the motor too: LAVA II 1S 280/320 mAh packs for the 0702, 480/580 mAh for the 0802, and 480/580/680 mAh for the 1102. Staying inside these tested combinations is the safest way to keep flight times and throttle response predictable.

Champion, Racing or Freestyle: Which KV Version Should You Buy?

Both the 0702 and 0802 families ship in three precision-tuned versions with distinct magnetic circuit and winding designs. The Champion versions carry the highest KV (36000 KV on 0702, 28000 KV on 0802) plus durable dual-ball bearings, and they produce the most power: 27.53 W and 7.17 A on the 0702, 34.3 W and 9 A on the 0802. They are aimed at professional racing where instant throttle response matters most.

The Racing versions sit one step down (30000 KV and 25000 KV) and are engineered for high RPM and razor-sharp response on technical race courses. The Freestyle versions trade top-end punch for smooth, efficient flying with superior low-throttle torque: 25000 KV / 15.01 W on the 0702 and 22000 KV / 22.73 W on the 0802. Note that Racing and Freestyle versions use brass bushings instead of dual-ball bearings. The 1102 comes in a single 21000 KV specification, so there is no version choice to make there — it is a dedicated freestyle and cinematic motor for 75mm-class whoops.

Why the 0.10mm Stator Core Matters in 2026

The headline engineering change in the 2026 generation is the industry-first 0.10mm stator core laminations used in both the 0702 and 0802 families. Thinner laminations reduce eddy-current and magnetic losses, which improves energy conversion and cuts heat build-up. BETAFPV’s testing puts the gain at a proven 0.1–0.2 g/W efficiency improvement compared with the previous 0.15mm-core motors — a meaningful margin in a discipline where a whole whoop weighs less than 25 g.

The 1102 takes a different route to the same goal. Instead of thinner laminations, it achieves 15% higher efficiency through an improved slot fill factor — more copper in the same stator slots — and pairs it with a 2000 series alloy outer rotor housing and a reinforced shaft for crash durability. Both approaches serve the same purpose: more power output and smoother throttle response from a single 1S cell.

How Do the 2026 Motors Handle Crashes and Wear?

Durability received explicit attention across all three families. The 0702 and 0802 use an upgraded rotor housing material and a reinforced shaft design to survive hard impacts and extend motor life. The 1102 goes further with a 2000 series alloy outer rotor housing, described by the manufacturer as built to withstand the hardest impacts — appropriate for the more aggressive freestyle flying a 75mm whoop invites.

Physical differences also hint at intended duty cycles. The 1102 uses a thicker ø1.5 mm shaft (5 mm long) with 28 AWG wire, versus the ø1.0 mm shafts and 30 AWG wire on the 0702 and 0802. Heavier props like the GF 1811 load the motor more, so the beefier drivetrain makes sense.

Frequently Asked Questions

Are the 0702, 0802 and 1102 (2026) motors all 1S?

Yes. All three families are rated at 4.2 V (1S). The difference is the battery capacity they are tuned around: LAVA II 1S 280/320 mAh packs for the 0702, 480/580 mAh for the 0802, and 480/580/680 mAh for the 1102. All use the same JST1.25 3-pin connector.

Can I put 0802 motors on a 65mm Air65 II whoop?

The official pairing is 0702 for the Air65 II and 0802 for the Air75 II. An 0802 weighs 1.95 g versus 1.59 g per motor and draws up to 9 A versus 7.17 A, so the swap adds 1.44 g of rotating mass and more current draw than the Air65 II’s 280/320 mAh packs are tuned for. The manufacturer’s tested combinations are the safe choice.

What does the 0.10mm stator core actually change?

Thinner 0.10mm laminations minimise magnetic losses, improving energy conversion and reducing heat. BETAFPV’s testing shows a 0.1–0.2 g/W efficiency gain over the previous 0.15mm-core 0702 and 0802 motors, which translates into slightly longer flight times and cooler running at the same throttle.

Champion, Racing or Freestyle — which version fits my flying?

Champion (36000/28000 KV, dual-ball bearings) is for racing pilots who want maximum power and instant response. Racing (30000/25000 KV) targets high-RPM agility on technical tracks. Freestyle (25000/22000 KV, brass bushings) prioritises smooth control and low-throttle torque for cinematic flying. Choose by discipline, not just by the biggest number.

Which propellers pair with each 2026 motor family?

The official recommendations are GF 1207 or GF 1219S 3-blade props for the 0702, GF 1614 for the 0802, and GF 1811 (or GF 45mm) for the 1102. Prop choice is part of the tuning, so deviating from these pairings will change thrust and current draw.

Do 1102 motors fit the original Meteor75 Pro frame?

Yes. The 1102’s recommended-parts list includes both the Meteor75 Pro II frame and the original Meteor75 Pro frame, along with the Matrix 1S 3IN1/4IN1, 5IN1 and 5IN1 II flight controllers. The mounting pattern (3×M1.4, ø6.6 mm) matches across the 2026 micro motor range.

Conclusion: Match the Motor to the Mission

The 2026 micro motor generation is refreshingly easy to navigate because each family is tuned for a specific airframe: 0702 for the Air65 II, 0802 for the Air75 II, and 1102 for the Meteor75 Pro II. Start from the frame you fly, pick the matching motor family, then choose Champion for racing, Racing for track agility or Freestyle for smooth cinematic work. Every specification in this guide comes straight from the official product pages — 0702, 0802 and 1102 — so you can verify each number before you buy.
