Customer reviews and experiences

What pilots love

The users of the compact Warbird are mostly enthusiastic about the flight characteristics. In numerous reports of experience, the amazing stability of the model is highlighted, even in light windy conditions. It is particularly appreciated that the authentic optics, which has been excellently reflected in the historical model of the British fighter from the First World War.

A recurring praise in the reviews applies to the pre-installed AS3X+ system, which effectively balances arches and turbulences and thus ensures a more calm flight behavior. Many users report that the model remains good for pilots with less experience.

Critical Points from the Community

Not all experiences are consistently positive. Some users complain about the durability of certain components, in particular the chassis, which can show weaknesses in harder landings. In addition, problems with the servos have been reported, which can lose precision after prolonged use.

Another criticism concerns the battery life. While the specified 8-12 minutes are sufficient for most users, some pilots want a longer flight time, especially if they want to exploit the full potential of the model.

Test results and flight properties

Flight behaviour

The Horizon Hobby model is characterized by a balanced and good-natured flight behavior. In tests, S.E.5a is extremely stable in the air and reacts precisely to control commands. The AS3X+ technology effectively balances wind blows, which is a decisive advantage especially for scale aircraft of this magnitude.

The model can be used for both cozy scale flights and moderate art flight maneuvers. With activated SAFE mode, the flight positions are limited, which gives beginners more security. Experienced pilots can disable this feature and exploit the full potential of the aircraft.

Increased power and speed

With the installed Brushless engine, the S.E.5a has an impressive climbing performance. It quickly reaches its travel altitude and offers enough power reserves for vertical climbing flights. The speed is appropriate for a scale model of this kind – not too fast for beginners, but dynamic enough for experienced pilots.

Material quality and processing

The EPO foam, from which the model is mainly manufactured, offers a good compromise between weight and stability. The detailed surface structures and the authentic colouring are particularly positive, which are reflected in the historical model.

The reinforcements at critical points, such as wing attachment and suspension, give the model additional robustness. Nevertheless, it should be noted that this is a foam model that can be correspondingly damaged when crashing.

Transport and storage

Transport capacity

With a span of 900 mm, the S.E.5a is compact enough to be transported in most vehicles. Practically, it is possible to remove the support surfaces, which considerably simplifies transport. The electrical connections between hull and surfaces are designed in such a way that frequent mounting and demonting is easily possible.

For safe transport it is recommended to purchase a padded bag or a special transport case to avoid damage. Many users report that they use self-modified solutions that work well.

Storage tips

For storage, the model should ideally be kept in a dry, not too warm room. The batteries should always be stored separately from the model and brought to a storage state of about 3.8V per cell. It is particularly important to protect the model from direct sunlight, since UV radiation can make the EPO foam brittle with time.

Spare parts supply and support

The spare parts supply for the e-flite model is excellent thanks to the popularity of the brand and the wide spread of the model. Horizon Hobby as a manufacturer offers an extensive range of original spare parts that can be purchased via the specialist trade or directly online.

Alternative models compared

Anyone interested in the S.E.5a should also take a look at similar models. Here are some alternatives in direct comparison:

E-flie Night Timber X Evolution 1.2m

With 1.2m, this model offers a larger span and is designed for STOL properties (Short Take-Off and Landing) and 3D art flight. Unlike historical S.E.5a, this is a modern bushplane design with LED lighting for night flights. The Night Timber offers more performance and versatility, but is also less original than the Warbird.

Parkzone Albatros D.V

Another historical model from the same era that offers similar flight characteristics. The Albatros represents a German fighter from the First World War and offers an interesting alternative for collectors of historical models. Processing and technical equipment are comparable to S.E.5a.

FMS Focke-Wulf 190

With a similar size but from another historical period (World War II), the FMS Focke-Wulf offers an alternative for lovers of German Warbirds. The model is faster and more agile than the S.E.5a, but does not offer the same modern flight technologies as AS3X+ and SAFE Select.

Value for money

With a price of about 220-250 euros, the E-flite model moves in the middle price segment. For this investment, the buyer receives a high-quality, largely flight-ready model with modern stabilization technology.

Compared to cheaper models without AS3X+ and SAFE Select, S.E.5a offers significantly better flight characteristics and more safety, especially for less experienced pilots. The quality of the components used and the attention to detail justify the price in the eyes of most users.

It should be noted that additional costs for a suitable LiPo battery, charger and a compatible remote control can be incurred if they are not already present. These additional costs should be taken into account in the purchase decision.

Tips, tricks and optimizations

Flight optimizations

For optimal flight properties of S.E.5a, experienced pilots recommend the following adaptations:

1. Priority optimization: The focus should be set exactly according to instructions. A slight forward shift can increase stability, but goes at the expense of agility.

2. Customize rudder rudder rudder: The factory settings are too aggressive for many pilots. A reduction in the set-offs to about 70-80% for the start can make the flight behavior significantly more humble.

3. Expo settings: By adding 15-20% of Expo to cross rudder and high altitude rudder, the control around the middle position becomes more gentle, which allows more precise flying.

4. Battery position: Experiment with the exact position of the battery in the hull to fine tune the focus. Even small shifts can affect the flight behavior noticeably.

Improving durability

In order to extend the service life of the model, the following measures have proved successful:

1. Suspension reinforcement: The standard suspension can be made more robust by reinforcements made of carbon fiber material. This prevents deformations in harder landings.

2. Servo equipment: The standard servos can lose precision when used intensively. An upgrade to high-quality digital servos improves control accuracy and durability.

3. Reinforce hinges: The rudder hinges can be infiltrated with a thin-liquid second adhesive to increase their strength without limiting mobility.

4. Surface sealing: A light coating with special foam seals protects the surface from moisture and contamination.

Performance increases

The following modifications are available for pilots wishing more performance:

1. Engine upgrade: A more powerful brushless motor with similar dimensions can increase the rise and speed. However, attention must be paid to the total weight.

2. Battery optimization: The change to a 4S battery with corresponding adjustment of the controller can bring a significant power boost. However, this requires experience and possibly further adjustments.

3. Propeller tuning: Experimenting with different propeller sizes and pitches can adapt the performance characteristic to the personal flight style.

Frequent questions and solutions

"My model responds to tax inputs delayed. What can I do?"

This problem can have several causes. It is often associated with interferences or a weak signal connection. First check the receiver's antenna position and make sure it is not shielded from metallic parts. A low battery voltage can also lead to delayed reactions. If the problem remains, a new connection of the recipient or a firmware update could be required.

"The flight time of my S.E.5a is shorter than expected. How can I extend it?"

To optimize flight time, you should pay attention to an efficient flight style. Avoid frequent full gas phases and extreme climbs. The use of a battery with a higher capacity can extend the flight time, but only up to the point where the additional weight does not affect the efficiency. An optimal compromise is usually at 1800-2200mAh. Also look at the state of your batteries – older LiPos lose capacity over time.

"The SAFE function does not work correctly. What is to do?"

For a correct function of SAFE Select, the model must be on a flat surface when it is switched on. This allows the system to calibrate the correct zero position. Also check whether SAFE has been activated correctly – this is done either during the binding or via an assigned switch on your remote control. If the problem remains, a resetting of the recipient to work settings and a new binding can help.

"The engine does not start, although everything is connected. What's that about?

Frequent causes of this problem are incorrect gas channel allocation, incorrect gas calibration or safety barriers of the receiver. Check if your transmitter is set to the lowest gas value before you turn on the model. Some systems require a specific gas billet position (usually at the bottom) to release the engine. A false cabling between controller and receiver or a defective controller can also be causes.

"How can I achieve the best flight performance in windy conditions?"

The AS3X+ technology helps with moderate wind. For even better results, it is recommended to move the focus easily forward and reduce the rudder deflections somewhat. Fly a little faster on wind than usual to achieve more stability. Avoid extreme maneuvers against the wind, as this can lead to control loss. A slightly increased flight weight can also improve wind stability, but is at the expense of agility.

Conclusion: Does the acquisition pay?

The E-flite S.E.5a 900mm BNF Basic with AS3X+ and SAFE Select is an excellent choice for model pilots looking for a historical aircraft with modern flight technologies. The combination of authentic appearance, good flying characteristics and helpful stability systems makes this model particularly interesting for advanced beginners and experienced pilots.

Particular emphasis should be placed on high-quality processing, good spare parts supply and the active community, which facilitate entry and possible problem solutions. The investment in this model is especially worthwhile for those who want to value an authentic flight experience with historical flair while benefiting from modern technology.

For absolute beginners, entry could be challenging despite SAFE technology, which is why previous experiences with simpler models are recommended. However, with the right preparation and some exercise, this model offers a long-term, satisfying flight experience that convinces with its versatility and the possibility of individual adaptation.
