Technical data: Overview table

Customer reviews and experiences

Numerous model flight enthusiasts describe their experiences with this 3D model as extremely positive. Especially praised:

• Flight behaviour: Many users highlight the precise control capability and the rich “locked-in” feeling that offers the combination of AS3X technology and SAFE select. Whether precise art flight or extreme 3D maneuvers – the model remains stable and predictable.
• Power reserves: The ability to operate on both 3S and 4S lips is perceived as an enormous advantage. With 4S batteries, almost unlimited vertical flight inserts and strong climbing flights are possible.
• Assembly and transport: There are hardly any criticisms. The toolless wing assembly with quick-release fasteners is repeatedly perceived as particularly successful and practical.
• Processing: The material quality of the EPO rigid foam and the high-quality impression of the servos are very appealing to users.
• Telemetry functions: The possibility of reading data such as battery voltage, current or temperature in compatible spectrum transmitters in real time offers considerable added value.

Few users report on small things, for example, that the battery shaft can be somewhat narrow for some larger 4S lips. Overall, however, the customer assessment is very positive.

Test results and practical reports

Various independent testers and experienced RC pilots have tested the model intensively. The main findings:

• Start and landing: Thanks to large-scale rudder and AS3X stabilization, the model can be easily mastered even during the first flight. Gentle landings also succeed in shorter slopes.
• 3D performance: Extreme rudder fittings and supplied Vortex generators ensure controlled knife flights, precise Torque Rolls and stable Harrier flights.
• Sports and art flight: Whether classic art flight figures or elaborate 3D maneuvers – the double-decker shows no control restrictions.
• Robustness: The model also puts harder landings away thanks to the flexible Z-foam. Smaller repairs are easy to accomplish.

In tests, easy handling is also highlighted for advanced beginners, provided they have first flight experience.

Material quality

The cells of the support surfaces and the fuselage are made of robust, fiber-reinforced EPO foam. The hollow core design ensures a very low weight with high strength. Shock, breaking and impact strength are often praised. All rows are split-free, and the metal transmission servos with ball sockets provide minimal play – a must for precise art and 3D flight.

The coating is applied cleanly, the decorative sheets are resistant to fuels and UV radiation.

Flight times and battery selection

With a 3S 2200–3200 mAh LiPo, 7–8 minutes are realistic depending on the flight style. With aggressive 3D flight (especially with 4S 2200 mAh), the flight duration can be reduced to about 5-6 minutes. The electronics are designed so that even longer flights are possible without overheating the engine or controller.

Increased power and performance data

Thanks to the powerful brushless drive combined with modern LiPo technologies, vertical climbing flights are easily possible. In operation with 4S batteries, “Unlimited Vertical Performance” and all common 3D maneuvers can be executed without significant power losses.

The high setting speed and the torque of the metal servos also make rapid change of direction and rolling axes possible – a must for advanced 3D pilots.

Transportability and storage

The model offers tool-free wing mounting with quick-release fasteners so that it is ready for transport in a few seconds. The removal of the wings significantly reduces the transport dimensions so that the aircraft fits into a trunk or the rear seat of many cars. The robust design also makes it less sensitive to small remplers during transport.

Spare parts supply

E-flite and the sales partners guarantee a very good spare parts availability. From supporting surfaces and hull parts to individual canvases, landing gears to distractions and decorative sets – virtually all components can be reordered. This facilitates repairs and gets the value of the model.

Target group

The E-flite Ultimate 3D Smart Model is aimed at:

• Advanced beginners (with first flight experiences)
• Art flight and 3D pilots
• Association flyers and performance-oriented hobby pilots
• All who are looking for a high-quality bind and fly model with state-of-the-art electronics

For absolute beginners without flying experience, the model is less recommended due to its 3D capabilities, unless the SAFE select system is consistently used and it is available to flight instructor support.

Construction and Guidance

The installation time is minimal: The assembly is carried out almost without tools, since the support surfaces are attached by quick closures. Rudder, steering and electronics are pre-installed. For a complete initial setup, including transmitter binding, battery selection and verification of all functions should be planned for about 35–45 minutes.

The guide is well understandable, contains numerous illustrations and describes the assembly and installation process step by step. Beginners can also find the right, as all safety instructions and tips for commissioning are clearly explained.

Tips, tricks, recommendations and optimization

Battery selection and focus

• Use a 3S 2200–3200 mAh battery for moderate flights, a 4S 2200 mAh LiPo is recommended for maximum vertical performance.
• The work-side focus is already well selected. If you prefer a rather quiet flight style, the battery can return to the rear minimally, for extreme 3D flight a light head load is recommended.

Rudder paths

• Use the maximum rudder deflections only after flight experience. For the first flight it is recommended to use a dual rate setting with damped stops.
• For 3D and art flight: Highly apply Expo values to keep the control in the neutral range soft, but to have enough fitting for extreme figures.

Telemetry

• Set up warning thresholds for battery voltage at the transmitter to allow a timely landing with an empty battery.
• Use the engine reversing function for extravagant maneuvers – condition: a compatible transmitter with 7+ channels.

Flight training

• Start using the SAFE select mode to get to know the model and flight characteristics.
• After several flights, switch to AS3X mode for maximum freedom in art flight and 3D maneuver.

Maintenance

• Regularly check servo hinges, hinges and motor fastening.
• Remove dirt and oil from rudder surfaces and engine.
