Blade 120 S2 RTF Radio Control Helicopter with SAFE - Beginner-Friendly Single-Rotor Trainer

Is the Blade 120 S2 a single-rotor or coaxial helicopter?

It is a single-rotor helicopter, not a coaxial model. It uses one fixed-pitch, flybarless main rotor with a direct-drive tail rotor. That layout flies and is controlled like a full-size helicopter, so the skills you build transfer to larger collective-pitch helis. SAFE technology adds the stability that makes a single-rotor machine approachable for beginners.

What battery does the 120 S2 use and what is included for charging?

It is powered by an E-flite 1S 3.7V 500mAh LiPo flight battery, and a USB LiPo charger is included in the box. Always charge on a non-flammable surface, never leave the pack charging unattended, and let a warm battery cool before recharging it. Check your manual for the exact charge time.

Is the 120 S2 a good helicopter for a complete beginner?

Yes. It is built as a beginner single-rotor trainer using SAFE technology, which adds self-leveling, bank and pitch angle limits, and one-button Panic Recovery. New pilots can build confidence quickly in the most stabilized mode, then move to less assisted modes for more control and agility as their skills improve.

What flight modes does SAFE technology provide?

The 120 S2 offers multiple flight modes. The most stabilized mode self-levels the helicopter and limits bank and pitch angles for your first hovers. Less assisted modes remove those limits for smoother turns, gentle maneuvers, and full control authority. This lets the helicopter grow with you as you progress from your first hovers onward.

What is Panic Recovery and how does it help new pilots?

Panic Recovery is part of SAFE technology. If you become disoriented during a flight, pressing the Panic Recovery button commands the helicopter back toward a level attitude, provided it has enough height and clear space around it. It acts as a confidence builder while you learn orientation and basic control inputs.

What comes in the box with the RTF version?

The Ready-to-Fly package arrives fully assembled with everything needed to start flying. It includes the helicopter, a multi-function Spektrum DSMX transmitter, an E-flite 1S 3.7V 500mAh LiPo flight battery, a USB LiPo charger, AA transmitter batteries, basic tools, and the instruction manual. Charge the battery, bind the model, and you are ready for your first hover.

What is the difference between the RTF and BNF versions?

Ready-to-Fly includes the transmitter and everything required to fly right away. Bind-N-Fly is the aircraft only and requires you to supply your own compatible Spektrum DSMX transmitter. Choose Ready-to-Fly if you do not already own a compatible Spektrum radio, and choose Bind-N-Fly if you already have one.

How do I bind the helicopter to the transmitter?

The Ready-to-Fly version is bound at the factory. To rebind, power on the transmitter first, then connect a charged flight battery to the helicopter while it sits still on level ground, and the model links automatically. For a safe connection, always turn the transmitter on first and turn it off last.

How long does each flight last?

Plan on roughly five minutes of flight time per charge of the 1S 500mAh LiPo pack. Always land when the low-voltage warning appears to protect the battery. Because each flight is short, many pilots keep several charged packs on hand and swap them between flights to keep practicing while a depleted pack recharges.

How big is the 120 S2 and how much does it weigh?

It is a compact micro helicopter with a main rotor diameter of about 330mm, which is close to 13 inches. Its flying weight is under 250 grams. The small size and light weight make it well suited to indoor practice in a room with enough open space, while still being capable outdoors in light wind.

Can I fly the 120 S2 indoors and outdoors?

Yes to both. This compact single-rotor helicopter is well suited to indoor flying in a room with enough open space, and it can also handle outdoor flight when winds are light. SAFE stability helps you hold position in a gentle breeze. Always clear the area of people and obstacles before you fly.

What maintenance does the 120 S2 need, and are replacement parts available?

Periodically inspect the rotor blades, linkages, and gears for wear, tighten any loose screws, and replace worn parts as needed. No manual gyro calibration is required; power on while the model rests level and the flight controller zeros itself. Replacement parts, including main rotor blades, are available, so keeping spares on hand reduces downtime after a crash.
