Technical data and facts at a glance

User Experiences & Reviews

Many users praise the entry-level friendly character. SAFE technology ensures a particularly stable flight property, which makes it much easier for newcomers to enter. The panic switch provides additional safety: If there is a loss of control, a push of a button is sufficient, and the aircraft is self-directed, which prevents crash landings.

Positive is highlighted:

• Robustness of the material: crashes and harder landings are often surpassed without damage due to resistant foam.
• Balanced flight characteristics: The model can be controlled slowly and precisely, but can also be mastered with ambitious manoeuvres.
• Spare part supply: The spare part layer is described as exemplary, common components are usually available at short notice.

Disadvantages according to customer experience:

• Flight time highly accurate
• With strong wind somewhat sensitive
• For absolute RC newbies, the setup of the electronics can initially be confusing

Many reviews emphasize that the aircraft remains reliable even after several seasons of intensive use and can easily perform repairs.

Test results and test reports

Professional journals and online portals judge the aeroplane almost consistently very positive. The overall concept as a training aircraft is repeatedly praised: The Apprentice STS sets standards in the safe learning of the RC aircraft. In the test, the combination of robust design, effective electronics as well as the versatile flight modes convinces.

In tests, intuitive control with SAFE technology is particularly highlighted. Another praise is the control over the spectrum receiver: The system reacts precisely and allows seamless binding with modern spectrum remote controls.

Material quality: Robust, durable, easy to repair

The fuselage as well as the support surfaces are made of resistant EPO foam. This material is lightweight, flexible and absorbs impact forces effectively. Repairs with commercial seconds or foam adhesives are easily possible. The accessories (bicycle, bearing surface connector, engine hood) are solid and also easily interchangeable.

Flight times: Depending on the battery – realistic and everyday

With the recommended 3S 3,200 mAh battery, flight times of about 8 to 12 minutes can be reached. If you pay attention to long sailing phases and save electricity, you can expand the flight time. For longer sessions it is recommended to purchase additional batteries that can be easily changed.

Ascending performance: Impressive for the model class

Thanks to Brushless drive and suitable propeller, the trainer achieves a very solid gradient. Low climbing flights are not permanently possible, but the excess of force is enough to quickly gain height or initiate dynamic maneuvers.

Transportability: Comfortable & practical

The surfaces can be removed with few handles, the complete model fits into many trunks. The low weight and compact dimensions facilitate transport even in public transport or on the bike. An optional carrying bag provides additional protection.

Spare parts supply: model and complete

With E-flite/Horizon hobby and numerous specialist dealers, the spare parts supply is excellently guaranteed. Long wear parts (propeller, chassis, engine hood, support surfaces, guide mechanisms) are usually available immediately.

Target group: Who is the Apprentice STS suitable for?

This model is aimed primarily at:

• Beginners and changers from other RC areas
• Advanced pilots who train stress-free or are looking for a robust everyday flyer
• Flight schools and clubs that want to perform beginners training

Advanced and pros can benefit from stress-free handling, as the model also fits very well as “Immer-dabei-flieger”.

Assembly & Guidance: Fast, Easy, Clear

The setup of the Apprentice STS is deliberately simple. Most components are already fully assembled. Only supporting surfaces and height guides have to be fastened and the electronics connected. As a rule, assembly takes less than 30 minutes, even without prior knowledge.

The guide is clear, well illustrated and leads step by step through the process. The set values for knockouts and center of gravity are shown graphically and in writing.

Community support: active worldwide & committed

The aircraft benefits from a particularly active and helpful community. In forums, social media groups and on YouTube there are numerous reviews, tips and solutions for typical problems. Also Horizon Hobby offers a good support with tutorials and videos.

Alternatives: Comparison with competitors products

The direct competition in this class includes models such as the HobbyZone Carbon Cub S 2, Multiplex EasyStar 3 and the FMS Ranger 1220. Below is a comparison of selected models:

The Apprentice STS offers the most user-friendly combination of robust design, variable flight modes and a comprehensive safety equipment.

Value for money

Even if the purchase price is slightly higher than in some competitors, the equipment and long-term quality and safety justify the investment. The reliable spare parts supply and the possibility to gradually expand the model allow the overall value to rise further.

Tips, tricks, recommendations and optimizations

Battery upgrade: Many users are increasing to batteries with higher capacity (e.g. 3,500 mAh) to further extend the flight time. It is important to pay attention to the weight in order not to negatively influence the flight characteristics.

Propeller choice: With frequent flying on meadows or asphalt, a more robust propeller is recommended to reduce damage to ground contact.

Chassis reinforcement: Those who often start or land on hard surfaces can make the chassis even more resilient with small reinforcements (e.g. carbon rods).

Secure binding: When connecting the model to the transmitter, the instructions should be carefully considered to exclude later range problems.

Portable bag: Especially for transport to the clubhouse or on travel, a precisely fitting bag pays off.

practice flight modes: Use the changeover function of SAFE flight modes during training to get familiar with the advanced flight skills step by step.

Frequent questions and problems with recommendations

Question: How do I bind the model to my transmitter?

• Answer: The binding takes place via the special switch on the receiver. It is important that transmitters and receivers are compatible (e.g. spectrum DSMX). Step-by-step instructions are included and are often found online as a video.

Question: My apprentice reacts delayed. What to do?

• Answer: Check the range and battery voltages of transmitter and receiver. Disorders due to other RC devices can also be a cause.

Question: How can I extend the flight time?

• Answer: Use batteries with higher capacity, reduce solid gas phases and practice energy-saving flight styles (e.g. sailing flight and gentle curves).

Question: Which adhesive is suitable for repairs?

• Answer: Commercial foam adhesives or second adhesives (cyanoacrylate-based) are suitable for EPO foam.

Question: The model moves to the left or right when starting. What to do?

• Answer: Check the rudder neutral position and the straight run of the suspension. If necessary, the side rudder must be trimmed.

Tips for advanced and improvements

• FPV retrofitting: The Apprentice STS can be equipped with an FPV camera, which opens up new flight experiences.
• GPS modules: It is possible to integrate optional GPS modules that transmit telemetry data.
• LED lighting: If you want to fly at dusk, you can retrofit LED strips.
• Reinforcement of plugs: By inserting additional carbon fiber rods, the support surface stiffness can be further increased.

What could buyers still be interested in?

• Upgrade options: The platform is open to many extensions, such as electronics, telemetry or light systems.
• Resale value: Due to the great popularity and popularity, the model can also be sold well for use.
• Training operation: Thanks to teacher-student operation (with compatible transmitters), safe common flying is possible.
• Availability: The model is currently available in Europe and worldwide via numerous retailers and online shops.
