More Capability

The Carbon-Z Cub SS features an updated wing design with drooped tips that adds wing and aileron area for better slow speed handling, performance and control – similar to the Plane Booster Wing Tip Set CubCrafters offers for many Cub models. Plus the modified flap design allows them to travel both ways for full-span aileron and other mixing capabilities.

More Convenience

Even with its giant-scale 84/2.1m wingspan, the Carbon-Z Cub SS is easy to store and transport because of the two-piece wing. And now it's more convenient than ever because no tools are required for field assembly/disassembly with the new thumbscrews. There are even decorative gas caps and antennas that snap onto the thumbscrews for added scale detail.

More Capable Gear

The new articulated and shock-absorbing landing gear, which is equipped with even larger oversized tundra-style wheels with softer tyres, offers better ground handling that easily soaks up the bumps of rough surfaces. An improved mounting design for the main gear makes it stronger than before, and fully-moulded top and bottom landing gear covers deliver a more scale-like appearance.

More Gear Options

An optional float set (sold separately) that includes a servo and functional water rudder, plus a new mounting/strut set (also sold separately) that attaches with a more secure rear mount and cross braces. Installation is easy, and you have the option to switch between floats and wheels in minutes. 6S LiPo recommended if taking off from water.

More Practicality

The push-button released, top-mounted hatch offers convenient and easy access to the battery compartment that holds a new quick-release, multi-position battery mounting tray (inspired by Morgan Mill RC) that fits most 4S to 6S 3200–7000mAh batteries.

More Reliability

The updated power system features a motor with an improved design that includes an additional bearing, along with a propeller that's moulded from material that better maintains balance and stiffness, to deliver smoother and more reliable performance. Plus the ESC is now equipped with an IC5 connector, which is also compatible with EC5 connectors, for better and more reliable power delivery.

Durable Precision

The lightweight and exceptionally strong airframe features composite-reinforced, hollow-core Carbon-Z construction. Best of all it arrives mostly factory-assembled and finished in a vibrant, high-visibility Carbon Cub SS Signature trim and color scheme. It also arrives with factory-installed digital, metal-geared servos and ball-link equipped linkages that deliver crisp and precise control.

Versatile Performance

From smooth and stable slow flight to beyond-scale aerobatics and everything in between, the Carbon-Z Cub SS has an extremely wide flight envelope that's perfect for first-time giant-scale and experienced pilots alike.

Bind-N-Fly Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX^® receiver featuring AS3X (Artificial Stabilization–3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence. The result is a heightened sense of stability and precision that makes you feel like you're flying a much larger, expertly tuned aircraft.

If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No programming is required. Simply change up the binding sequence as directed in the manual.

With SAFE Select enabled, you get:

Pitch and Bank Angle Limits

These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.

Automatic Self-Leveling

The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It's also helpful for keeping the wings level during takeoffs/launches and landings.

Easy Switch Assignment—No Complex Programming Required

The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn't require any complex programming and takes just a few seconds.

If you don't want to enable the SAFE Select features, just bind the receiver normally and it will function like a standard AS3X receiver.

Wingspan: 2149 mm
Battery type: 4-6S 4000 - 7000mAh LiPo, 6S LiPo recommended if taking off from water (both sold sepratley)
Length: 1430 mm

The EFL RC Aircraft with 2149mm wingspan is designed for large-scale flyers who value performance, versatility, and stability. With a commanding wingspan of over two metres and a fuselage length of 1430mm, this aircraft offers enhanced lift and glide characteristics.

Whether you're flying off grass fields or calm lakes, this aircraft provides smooth, confident performance in a variety of flight environments.

What are the key features of this EFL RC Aircraft?

2149mm Wingspan – Large wing surface area for superior lift and long gliding efficiency.
1430mm Fuselage Length – Balanced body dimensions enhance directional control and aerodynamic flow.
4S–6S LiPo Battery Support – Wide voltage compatibility with recommended 6S for aquatic take-off strength.
4000–7000mAh Capacity Range – Allows for endurance tuning or added thrust, depending on mission goals.

Excellent Glide Characteristics – Ideal for scale, sport, or extended cruising missions.
Large Visual Presence – Easy to track during flight for better orientation and visual piloting.

Why is a 6S LiPo recommended for water take-offs?

Water take-offs require greater thrust to overcome drag at the water’s surface. A 6S LiPo battery (22.2V) delivers the extra voltage and power needed for strong acceleration and clean liftoff. While 4S and 5S batteries can still provide adequate performance on solid ground, the higher energy density of a 6S pack ensures more confident water operations, especially in less-than-ideal conditions.

What are the advantages of the 2149mm wingspan?

This expansive wingspan delivers stable flight behaviour, extended gliding capability, and smoother turns even in windy conditions. The size also reduces wing loading, which improves low-speed handling and helps with scale-like flying performance. Whether you're cruising or thermalling, this wing design supports long, efficient flight with minimal input correction.

Is this aircraft ideal for advanced hobbyists?

Yes. Its size, power system flexibility, and water-ready performance make it best suited for intermediate to advanced pilots. The model is highly responsive in the air while remaining stable, and its large size offers a commanding presence without becoming cumbersome. With proper setup, it becomes a multi-environment performer—just as suited to water as it is to dry land.

What batteries can be used?

This aircraft is compatible with 4S to 6S LiPo batteries within the 4000mAh to 7000mAh range. Lighter 4S setups may offer longer flight times with reduced top-end power, while 6S packs deliver peak thrust and faster climb-outs—especially important for heavier loads or water-based operations. Batteries are sold separately, giving you full freedom to customise your flight style and runtime.

How portable is a model of this size?

Despite its scale, the aircraft has been designed for field convenience. Wing panels may be removable (depending on model design), and the 1430mm fuselage makes vehicle transport manageable. Once assembled, its broad stance and powerful battery setup deliver a large-model experience with refined flight behaviour and energy-efficient cruising.
