E-flite Carbon-Z Cub 2.1m BNF Basic with AS3X (EFL10450): Detailed guide for buyers

The E-flite Carbon-Z Cub 2.1m BNF Basic with AS3X (EFL10450) is one of the most advanced and versatile RC aircraft in the current market segment. With its impressive range, modern electronics and high processing quality, this model addresses both ambitious beginners and experienced RC pilots. In this article you will find a comprehensive overview of all relevant aspects, technical details, user experiences, test results, company tips and many further information that allows an informed purchase.

Technical data and facts

Customer reviews and experiences

The Carbon-Z Cub 2.1m is often praised as extremely robust, reliable and versatile. In particular, the large flight image and the precise control by AS3X and SAFE are highlighted as a highlight. Many users report an above-average stable flight behavior even in windy conditions – even fewer experienced pilots clearly benefit from this.

The rapid assembly is also rated positively: Most buyers need less than one hour, as the components are manufactured accurately and the cabling is pre-installed cleanly. The instructions are described as understandable and beginner-friendly, which minimizes the likelihood of errors during initial setup.

Some users emphasise that the model can be moved both casually as a classic coach and sporty agile. The optional use of 4S to 6S batteries gives room for different performance and flight profiles. When transitions from beginners to advanced models, many appreciate the adaptability and long service life of the components.

Overview of test results

Various model building journals and online portals have tested the model. In flight tests, the balance between performance and flight comfort prevailed. The factory-adjusted flaps enable short start and landing distances, which also brings great advantages in smaller flight fields. In test operation, the quality of the digital metal transmission servos was highlighted – they provide exact feedback and also defy the continuous use.

The brushless engine provides sufficient thrust for vertical climbing flights and shows no tendency to overheating even in long flight maneuvers. Critical voices occasionally complicate the high surface load in the landing approach, which can lead to faster landings – here practical training and, if necessary, a cautious focus adjustment helps.

Material quality

The model is made from high-quality EPO. This special rigid foam is at the same time lightweight, stable and very shock-resistant, which significantly reduces the risk of damage in case of hard landings. The main support surfaces reinforce additional carbon fiber spars, whereby the structure remains torsion-resistant even in the case of spaghal flight maneuvers. The plastic used is UV-stabilized and retains its shape and brilliant coloration even after many flights.

Flight time and drive concept

The flight time varies between 4 and 10 minutes depending on the battery and flight style. With a 6S 5000mAh battery, flight times at the upper end of the spectrum are realistic, while in the case of sporty flight or art flight inserts the duration drops accordingly. The drive package is designed in such a way that powerful climbing flights and long sliding phases remain possible even with medium battery capacities.

Increased power

The gradient of the model is one of the best of its class. The powerful brushless motor in combination with the large, aerodynamically optimized surfaces ensures effortless climbing, even under load (e.g. with optional towing coupling for sailors). Lower vertical maneuvers can be easily realized with a 6S drive. There is plenty of power available for broaching and short start maneuvers.

Transport and handling

With a span of more than 2.1 meters and the stable construction, the model is not exactly small, but thanks to the removable support surfaces and the divided control unit, it is still suitable for transport in the car. The wings are fastened without tools by quick-release fasteners, which makes it noticeably easier to lift and remove. Many pilots transport the model with the main chassis mounted and only build the areas at the airfield.

Spare parts supply

The spare parts supply is secured and runs directly through numerous dealers and manufacturers. From hulls and surfaces to chassis components to small parts, all spare parts are available at short notice. In the longer term there is also good spare part logistics, as the model and related aircraft of the same manufacturer are widely used.

Target group

The model is aimed at advanced beginners and experienced pilots who are looking for a robust, reliable flying large model that can be used both as a classic coach and dynamic art flight. For absolute beginners, entry with support (e.g. flight instructor or flight simulator training) is also possible, as assistance systems such as SAFE and AS3X provide a lot of security.

Construction and Guidance

The structure is uncomplicated thanks to pre-installed electronics, servo-cable wings and precise components. Usually the model is ready to fly in less than an hour. The guide leads step by step and with many images through the setup process, which is especially beneficial to beginners. The illustration also clarifies cabling, focus and setting of the surfaces.

Community support

An active community has formed around the E-flite Carbon-Z Cub 2.1m. In many RC forums, Facebook groups and on YouTube you can find tips, rebuild ideas, reviews and answers to frequent questions. The manufacturer also maintains a detailed FAQ and support area.

Alternative products of competitors

Those seeking alternatives should consider the following models:

The E-flite Carbon-Z Cub 2.1m offers the best overall package in puncto size, equipment and assistance systems. The Cessna 150T from the same house is an alternative for friends of classic high-decker look with comparable electronics.

Value for money

Given the generous equipment with digital electronics, assistance systems and robust design, the price-performance ratio is to be classified as very good. Spare parts and accessories are affordable, the longevity of the model compensates for entry costs. In particular, the evaluation is positive compared with similar large models and the range of services offered.

Tips, tricks and recommendations

1. Battery care:
Use high quality 4S to 6S LiPo batteries. For maximum flight duration and engine life, it is recommended to never completely empty the batteries and to observe storage voltages.

Two. Priority:
Check the focus before each flight. A few millimeters of difference already affect the flight behavior. Rule of thumb: The model flies more calmly.

3. Area:
When attaching and disassembling, pay attention to the plug connections of the servos and surfaces to avoid cable breakage.

4. flaps and flight modes:
Experiment with different landing flap positions and flight modes (SAFE, AS3X-only, manual) to achieve the optimum flight feeling for the current use.

Five. Tyres and suspensions:
Anyone who regularly starts at uneven places can mount larger tundra wheels or adjust the chassis of softer dampers.

6. Individualization:
With LED navigation lights, drag couplings or floats, the Cub can be upgraded further – the community offers numerous instructions.

Questions, problems and solutions from practice

Question: My model moves slightly to the left in a straight trip.
Solution: Check the rudder trim and the straight run of the spoon wheel. If necessary, the rudder center must be adjusted at the transmitter or mechanically at the rudder steering.

Question: The engine does not run, although everything is correctly connected.
Solution: Check if the battery is fully charged and correctly connected. In addition, the transmitter binding should be restored. A view of the plug and the telemetry signal at the receiver is also worthwhile.

Question: The landing flaps don't go out.
Solution: Check the power cabling and whether the function in the transmitter has been correctly assigned. The servo programming may have to be checked or the channel must be re-allocated.

Question: Where can I find spare parts?
Answer: Spare parts are offered via dealers or directly via the manufacturer. There is a wide supply for all components – from hull and surfaces to small parts and servos.

Question: Can I drag the model?
Answer: Yes, with optional towing coupling, the model is excellently suited for sailing.
