Technical data and facts in table form

Customer reviews and experiences

The majority of users rated the Slow Ultra Stick extremely positively, especially for its flight characteristics and easy handling. Many buyers note that despite its small size, the model flies very stable and remains easily controllable by the AS3X stabilization itself in wind. The SAFE Select technology supports beginners by making flights safer and easier and significantly reducing unwanted crashes.

Experience reports also praise the included remote control for their intuitive usability and the good range, which significantly improves flight feeling. Some users report that the flight time varies from about 12 minutes depending on the flight style, which is considered very good for a model of this size.

It was sometimes criticized that the propeller is susceptible to damage, but the "pop-off" prop seed and the spare part supply compensate for this disadvantage, since damaged parts can be easily exchanged. In total, many owners felt the model as highly recommended for beginners and as an entertaining device for experienced pilots who like slow-flying.

Test results in detail

In detailed tests, the Slow Ultra Stick impressed with its precise control and very stable flight behavior. Thanks to the AS3X system, wind and turbulence is effectively balanced, which makes flying very pleasant. SAFE Select technology increases flight safety by automatic stabilization and a panic function that gently returns the model to a stable flight position in case of emergency.

The gradient is remarkable for an ultra-light model. The flight model rises rapidly and evenly, which leads to an impressive flight picture especially in minimal wind conditions. During the tests it was also shown that the model reacts very agilely to control commands and controls both slow, controlled flight phases and fast, maneuvers without problems.

The flight time reaches about 10 to 14 minutes under normal conditions at full battery capacity, which is a very good value for a battery of this size. The supplied charger via USB-C also enables practical and fast charging cycles.

Material quality and processing

The aircraft consists of a lightweight but durable foam material that is specially designed for the loads of flight operation. Despite its low weight, the construction is robust and resistant to smaller impacts or crashes. The stability of the hull and the supporting surfaces ensures that repairs are rarely necessary.

The manufacturer has placed particular attention on the propeller: The "pop-off" design protects the engine and the design by simply letting the propeller loose during collisions and thus preventing greater damage. This security feature significantly increases the longevity of the model.

The components included in the scope of delivery, such as servos, motors and electronics, are optimally installed and matched to each other at the factory, ensuring high reliability.

Flight times and climbing performance

The flight time with the 150mAh 1S LiPo battery supplied is typically in the range from 10 to 14 minutes, depending on flight style and wind conditions. For a model of this size, this is a very good value that also allows longer training sessions.

The climbing performance is impressively good thanks to the efficient brushless motor combined with the lightweight construction. Even at the highest level, the model can quickly gain height without losing stability.

Transport capacity

Due to its compact dimensions of almost 50 cm span and under 45 cm length and a weight of only about 42 grams, the aircraft is very transportable. It fits comfortably in small backpacks or even larger jacket pockets. The construction takes place quickly without lengthy assembly, which allows spontaneous flights at different locations.

Spare parts supply

The spare part supply for the Slow Ultra Stick is well organized. Propellers, motors, servos, hulls and other important components can be easily reordered by the manufacturer or specialist dealer. Thanks to the modular design, damaged parts can be easily replaced, which significantly extends the service life.

Target group

This model is aimed primarily at:

• Entrepreneurs who want to enter the RC fly uncomplicatedly and benefit from the security features,
• Advanced pilots looking for a handy, precise Slow-Fly model,
• model flyers who want to fly indoors or in small outdoors,
• Pilots who value a good set of equipment (RTF – Ready to Fly).

Construction and Guidance

The model is delivered as a RTF set, so that the actual assembly is minimal. The included instructions are clear and understandable, and it leads step by step through the installation of battery, transmitter and flight control.

The time required for the start is usually only 10 to 15 minutes, including charging of the battery and the first setup. Beginners with little experience can also find themselves well thanks to the comprehensive documentation.

Community support

Since the Slow Ultra Stick is very popular, there is an active community of model flyers. In online forums, social media and specialized platforms, users regularly exchange tips, tricks and individual experiences. In particular, newcomers offer valuable help in questions about technology and operation.

Alternative products of competitors

In the field of ultra-micro slow flyers there are some comparable models, including:

While the Slow Ultra Stick scores with its combination of AS3X and SAFE technologies, competitors offer different control or material concepts. The price-performance ratio of the UMX Slow Ultra Stick is, however, particularly attractive due to the high-quality equipment in the set.

Value for money

The price for the complete package including battery, charger and professional transmitter is in the middle segment for ultra-light RC models. In view of the supplied technologies such as AS3X, SAFE Select and RealFlight Simulator software and the quality of the flight model, the overall price-performance ratio is very good.

Tips, tricks, recommendations and optimizations

• Improving flight practice: Use the included RealFlight Trainer Edition as a simulator to practice flights and avoid crashes.
• Battery care: Charge the LiPo battery with the supplied USB-C charger carefully and avoid low discharge to maximize service life.
• Replacement propeller on stock: Due to the sensitivity of the propellers, it is recommended to have replacement propellers always ready to handle.
• Customize flight modes: Experiment with dual rate switches to adjust control sensitivity to your skills.
• Easy to repair: Small cracks or damage in the foam can be quickly repaired with special foam adhesive.
• Outdoor flights by wind: Although the model also carries some wind, an indoor flight should be preferred for stronger winds.

Frequent Questions and Problems – Overview Solutions

Question: Why does the plane sometimes react sluggishly to control commands?
Answer: Check the battery level and the binding between transmitter and receiver. A somewhat unloaded battery or faulty binding can delay the control. In addition, the SAFE function can damp the control in beginners mode.

Question: How can I extend the flight time?
Answer: Avoid aggressive flight manoeuvres, which heavily load the battery, and fly in wind silence. Additional LiPo batteries help increase flight time by quick battery change.

Question: What do I do with a propeller damage?
Answer: Thanks to the Pop-Off-Prop-Savers you can easily swap damaged propellers. Spare parts are readily available.

Question: Is the transmitter compatible with other models?
Answer: Yes, the spectrum SLT6 transmitter supports many spectrum compatible models; for the best results, however, binding and adjustment should be made.

Question: How robust is the model when crashing?
Answer: The lightweight foam construction is robust, but parts can break when heavy crashes. Thanks to good spare parts supply and easy repair, this is not a big problem.

The E-flite UMX Slow Ultra Stick RTF with AS3X and SAFE Select (EFLU03000) is an excellent model for beginners and advanced users looking for a compact, easy to fly and yet technically high-quality RC aircraft. With sophisticated technology, easy operation and extensive equipment, it convinces in many aspects and provides a very good basis for both entry and further flight exercises.
