The Blade Nano series, renowned for its innovation and user-friendly features, presents two remarkable models: the S2 and the newer S3. In the following comparison, we delve deep into the technicalities, performance, and compatibility aspects of both helicopters, aiming to provide potential buyers with a comprehensive insight into what each model has to offer. Whether you’re a seasoned pilot or a beginner eager to take to the skies, this guide will help illuminate the path to your next purchase.
Blade Nano S3
SAFE Z Altitude Control: Similar to the S2, it utilizes the onboard accelerometer to maintain altitude. However, it’s highlighted as an improvement over the S2.
Performance: Similar to the S2, it offers dazzling 3D maneuvers. Linear servos provide impressive control authority, and the 45C LiPo flight battery ensures efficient power for 3D flight.
Durability: Like the S2, it is constructed with super-resilient polymers and features a carbon-fiber main shaft and tail boom.
Compatibility: Most parts from the Nano S2 are compatible with the Nano S3.
Flight Controller Tuning: While both models have flight controller improvements, the S3 emphasizes a completely re-tuned controller, possibly offering better control and stability than the S2.
Improved SAFE Technology: Both models feature SAFE technology, but the S3 mentions improvements over its predecessor, especially in stability and panic recovery.
The S3 has built-in voltage telemetry which provides real-time voltage updates to a compatible transmitter. This feature can be essential for real-time monitoring of battery status.
Built-in Telemetry: Offers built-in voltage telemetry that directly sends data to a compatible Spektrum™ transmitter.
Flight Controller Improvements: Comes with a totally re-tuned flight controller that improves the AS3X® stability, an improved SAFE® mode with angle demand, and improved panic recovery.

Blade Nano S2
Stabilizing System: Introduced the SAFE® stabilizing technology which made it easier for pilots to stabilize the helicopter in case of disorientation. This technology was particularly useful for beginners, allowing them to immediately lock the model in a perfectly level attitude.
SAFE Technology Features: It had a custom-tuned AS3X® system at the heart of its SAFE technology, along with improved SAFE Angle Demand and Panic Recovery features.
New Altitude Control: Introduced the SAFE Z Altitude Control that uses the Heli’s onboard accelerometer to maintain a consistent altitude.
Flight Controller: The flight controller was mounted vertically to improve damping and remove vibration to the gyro.
Performance: Capable of full aerobatic tricks with its collective pitch design. It had strong coreless motors a 45C LiPo flight battery for 3D flight, and linear servos for impressive control authority.
Durability: Made with super-resilient polymers and features a carbon-fiber main shaft and tail boom.
Compatibility: Most parts from the Nano CP S are compatible with the Nano S2.
Recommendations: Which is Better?
If you value real-time battery monitoring and potentially better stability and control, the S3 seems like the logical choice. It builds upon the strengths of the S2 and introduces new features that enhance the flight experience. However, if these improvements aren’t significant for your needs, and you’re looking for a model that’s tried and tested, the S2 remains a solid option.
