Technical data and facts

Customer reviews and experiences

Users praise the versatility of use – from relaxed soaring to sports acrobatics to FPV flight (First Person View). Many emphasize the high flight stability, which also allows beginners a safe flight. The AS3X stabilisation system and SAFE Select are particularly known as useful features that significantly improve handling in wind and turbulence.

A common point: The assembly is simple, the wings can be fastened in a few minutes thanks to the plug system. The precision of fit of the components is praised. However, some report that there is a need for some patience in cable routing and connection of the plug contacts during initial assembly.

Many customers are positive about material quality. The mix of Z-FoamTM and carbon reinforcements ensures high torsional stiffness and longevity without unnecessarily increasing weight. Drops from a small height were easily pushed away in most cases.

Thanks to the modular plug-in system, the model fits easily into the trunk of a middle class car.

Overview of test results

Independent test reports confirm the high quality of the Opterra naval wing. Particular emphasis is placed on:

• Precise control thanks to the digital stabilization system, which also ensures quiet flights in difficult conditions
• Powerful drive with optimal climbing performance for fast altitude gains
• Multiple camera optionswhat makes the model particularly attractive for FPV fans and videographers
• Easy transport by removable wings and winglets

In most tests, the instructions are clearly structured and understandable. Graphics and step-by-step descriptions help to avoid typical errors when building. The average build-up time is about 20-30 minutes for trained model builders.

Material quality

The aircraft consists predominantly of Z-FoamTM, a very durable but lightweight special foam that is reinforced with a carbon casing at the critical points. This combination guarantees high durability and long service life. Even after small remples or more robust landings, the model remains stable and without significant damage.

Flight times and climbing performance

With a recommended battery (3S, 2200–3200 mAh LiPo), pilots achieve average flight times between 15 and 25 minutes, depending on flight style and weather conditions. With predominant soaring and low engine life, longer flight times are also possible.

The climbing power is impressive for a single wing of the 2-meter class. The powerful brushless drive allows rapid climbing flights, loopings and even simple art flight maneuvers.

Transport capacity

A real plus: Thanks to removable wings and winglets, the model can be transported particularly space-saving. All components are designed for quick disassembly so that even spontaneous flights after the evening are easily possible.

Spare parts supply

The manufacturer E-flite and numerous dealers offer a wide range of spare parts – from wing ends to servos to complete fuselage sections. This ensures a long service life and even repairs after more violent incidents can be easily realized.

Target group

This model is aimed at dedicated hobbyists who have already collected first flight experiences. The Opterra hurdle is ideal for advanced beginners, but also offers experienced pilots a lot of space for further development thanks to FPV option and art flight suitability. Even less trained pilots can quickly celebrate success through the stabilization systems.

Construction time and instructions

The assembly is usually done in less than 30 minutes. The guide impresses with clear illustrations and a comprehensible layout. Especially positive: clues to typical stumbling traps and tips for a smooth first flight.

Community support

The community around this flight model is active and helpful. In numerous online forums, Facebook groups and video platforms, users regularly exchange information on flight experiences, tuning ideas and repair tips. Beginners benefit from built-in videos and setup instructions as well as experience reports on different camera and battery configurations.

Alternative products of competitors

In addition to the E-flite Opterra 2m single wing PNP (EFL11175), there are some other single wing models on the market that offer similar services. These include:

These models differ in size, equipment and audience. The selection should pay particular attention to the availability of spare parts, suitability for FPV and personal experience.

Value for money

The price-performance ratio is classified as very good by most owners. A modular, high-quality machined model with modern technology is available for the price called, which is suitable both for classic RC hedge flights and for exciting FPV missions. In addition, the solid spare parts supply is added, which additionally increases the value.

Technical Report: Tips, Tricks and Optimizations

1. Battery selection and focus:
Many pilots recommend choosing the battery so that the recommended weight window is maintained. A 3S-3200mAh battery offers the longest flight time, but ensures a somewhat preloaded center of gravity, which can be compensated with light lead weights or a slight relocation.

Two. Camera use:
For FPV flights, it is recommended to use a light HD camera to keep the weight low. The three existing brackets allow different perspectives and the combination of live image and recording.

3. Area reinforcement:
In the case of more extreme flight maneuvers, it is advisable to additionally secure the wings on the plug connections (e.g. with adhesive tape or small carbon fiber pins) in order to avoid twisting.

4. Optimize landings:
The model is designed for sliding landings. On rough substrates it is recommended to attach wallpaper to the wing bottom that protect the foam from wear.

Five. Telemetry:
Many pilots equip the model with telemetry to keep the battery voltage in sight during the flight and land in time.

6. Software update:
Before the first flight it is recommended to install the most up-to-date firmware for the recipient used to take advantage of the full advantages of the stabilization technique.

Questions and problems of users: Frequent answers and solutions

Question: Can I fly the model without a stabilization system?
Answer: Yes, the stabilization system can be disabled by transmitter. For experienced pilots, a very agile, direct flight behavior results.

Question: Which servos should I use in an exchange?
Answer: High-quality digital metal transmission servos are best suited to ensure full control and reliability.

Question: How can the flight time be extended?
Answer: In addition to a larger battery (in the context of the recommendations), a saving use of the drive and the use of Thermik helps.

Question: Which transmitter is suitable?
Answer: A spectrum DSMX/DSM2 compatible transmitter with at least 4 channels and Elevon mixing function is recommended.

Problem: The plane's trudging on tearing.
Solution: Control center of gravity, check areas for damage and, if necessary, reduce the rudder impact.

Problem: Camera shots wail.
Solution: Check camera mount on fixed seat and possibly dampen with moss rubber.

Buyers: What else should you know?

• Upgrade potential: The model can be equipped with more powerful drives, light systems or telemetry modules.
• Weather resistance: Thanks to AS3X can be safely flown with wind.
• Value stability: E-flite models are needed, which keeps the resale value high.
• Various applications: From relaxed thermal flight to action-rich FPV races – the Opterra can be used flexibly.
