0702 FPV Motor Buying Guide: How to Choose the Best Motor for Your 65mm Whoop Drone
0702 motors have become a popular choice for ultra-lightweight 65mm whoop drones due to their incredibly low weight, high KV options, and exceptional efficiency on 1S power. In this guide, we’ll walk through how to choose the right 0702 motor for your build, compare key options, explain performance differences, and even show how to build your first 65mm whoop using these motors.
Choosing the Right 0702 Motor: What Matters Most
When selecting a 0702 motor, consider the following factors:
-
KV Rating: Determines motor speed. Higher KV = more RPM = more punch, but more current draw.
-
Weight: Affects total AUW (All-Up Weight) and responsiveness.
-
Bearings: Dual ball bearings offer smoother performance and longer lifespan than bushings.
-
Build Quality: Material quality and magnet strength affect both thrust and durability.
-
Voltage: All 0702 motors listed here are designed for 1S (4.2V) builds.
Recommended KV by Flight Style:
-
22000KV – Control-oriented, efficient cruising
-
23000KV–25000KV – Balanced freestyle
-
26000KV–27000KV – Aggressive freestyle/racing
-
28000KV–30000KV – Maximum punch, indoor track racing
Top 0702 Motor Options Compared
| Model | KV Options | Weight | Bearings | Max Power | Notes |
|---|---|---|---|---|---|
| Happymodel SE0702 | 23000 / 26000 / 28000 | 1.5g | Bushing | ~14.8W | Great for budget builds, solid thrust data with Gemfan props |
| BETAFPV 0702 II / SE II | 23000 / 27000 / 30000 | 1.45g–1.55g | Ball / Bushing | ~16W | Dual-bearing (II) or budget-friendly SE options, highly optimized for indoor race |
| RCinPower GTS V3 | 27000 / 29000 | 1.5g | Dual Ball | ~19.7W | Premium build, high power, top-tier balance and consistency |
| NewBeeDrone Flow 0702 | 27000 | 1.38g (no wire) | Dual Ball | 15.2W | Lightest with wiring, made for AcroBee and BeeBrain FCs |
| VCI Spark 0702 | 22000–29000 | 1.52g | Dual Ball | Up to 16W | Strong OEM backing, wide KV range, excellent build finish |

Bench Data Insights: Real Performance
The Happymodel SE0702 motors provide published thrust tests:
-
With 31mm bi-blade props on 3.7V:
-
KV23000: ~21.7g @ 2.86A
-
KV26000: ~21.7g @ 2.8A
-
-
With 40mm bi-blade props:
-
Up to 27.1g @ 4A (KV23000)
-
Conclusion: Thrust scales with current draw. For peak thrust (20g+), expect ~2.5A–3.5A current draw. Pairing with lightweight props (e.g. Gemfan 1210, HQ31mm) is critical.

Build a 65mm Whoop Using 0702 Motors
Recommended Components:
-
Frame: BETAFPV Meteor65 / NewBeeDrone AcroBee65 / Happymodel Mobula6 frame
-
Flight Controller: AIO with 5A ESC (e.g., BeeBrain BLV4, BETAFPV F4 1S 5A AIO)
-
Props: Gemfan 1210, Gemfan 1208, HQProp 31mm bi-blade, AZI 1.0 3-blade
-
Motor: Any 0702 with 1mm shaft (see above chart)
-
Battery: 1S 300–450mAh LiHV (BT2.0 / PH2.0 connector)
Build Tips:
-
Use PEEK screws if weight-saving is critical (e.g., BETAFPV 0702SE kit)
-
Optimize p-gain/d-gain for higher KV motors
-
Check motor plug compatibility (some motors use JST-1.0, others need direct soldering)
0702 vs 0802: Which Should You Choose?
| Feature | 0702 | 0802 |
| Weight | ~1.4g–1.6g | ~1.9g–2.2g |
| Torque | Lower | Higher |
| Thrust | ~20–28g | ~30–38g |
| Efficiency | Higher (low throttle) | Lower (but stronger punch) |
| Ideal For | 65mm builds, low AUW, precision | 75mm builds, acro, more aggressive flight |
Verdict:
-
Choose 0702 for tight indoor tracks, sub-20g AUW, and smoother control.
-
Choose 0802 if you fly more outdoors or want raw power.
