Technical data and facts

Customer reviews and reviews

The response to the Habu STS 70mm EDF from E-flite is mostly positive. The following points are particularly frequently mentioned:

• Easy handling/flight: Many buyers emphasize that the jet is also suitable for absolute beginners. The SAFE system takes a lot of work off the pilot, automatically corrects faults and ensures that the model always remains stable in the air. The three-stage control (beginners, advanced experts) is described as very helpful.
• Flight image and performance: Users report a more agile flight image than most coaches. Even at low speeds, the control remains precise, which facilitates start, landing and flight maneuvers.
• Processing quality: The robust EPO cell ensures high impact strength. Even after hard landings, there are rarely significant damage – ideal for learning phases.
• Assembly: The assembly is described as extremely user-friendly. Many customers report that the construction is done in less than an hour without special tools or adhesive being required.
• Safety/assistance systems: The optionally available landing aid sensor (LAS) is particularly estimated, which automatically initiates a flare maneuver and avoids harder landings.

However, there are also critical clues:

• Some users feel the flight time with standard battery as a bit short, especially in sports flight.
• Advanced pilots occasionally want a little more speed or climbing performance.

Overview of test results

In practical tests, specialist magazines and experienced model pilots come to similar assessments as everyday users:

• SAFE System & Smart Components: The combination of flight assistance and telemetry is assessed as exemplary. The three flight modes help to optimally shape individual learning curves and avoid accidents.
• Start/country characteristics: As one of the few jet models, this model is also suitable for grass pistes. Thanks to extensive running gear with large wheels and controllable boom, the model remains stable when rolling, even on uneven slopes.
• Drive & air performance: The factory-installed Brushless unit offers solid performance with 3S battery, but can be upgraded to 4S for sporty flying without any modifications.

Processing and material quality

• Cell and Structure: The model consists of high-quality EPO foam, known for its combination of lightness and robustness. Shock resistance is a great advantage in practice and in land-emaneuvering. The coating and the fit of the individual components are described as clean and high quality.
• Suspension: The three-legged suspension with oversized wheels and steerable boom convinces in everyday testing. It allows starting and landings on asphalt, trails and short-cut grass.
• Installation-friendly: Most parts are preassembled on the factory. The final assembly does not require any adhesive or special tool, which significantly reduces the crash risk during the first construction.

Flight times and battery management

With a recommended 3S 4000mAh LiPo battery, the jet typically flies between 4 and 7 minutes, depending on the flight style and weather conditions. According to test reports and user information, up to 8 minutes can be reached with a moderate style. If you are upgraded to a 4S battery, you will get significantly more thrust, but you will have to expect slightly shorter flight times. The telemetry monitoring of the battery level ensures additional safety by warning against a discharge in time.

Practical tip: Several batteries and a faster charger are worthwhile if longer flight times are desired at the time.

Increased performance and flight behaviour

With the standard 3S battery, the drive system delivers a balanced mix of train and efficiency. In the climbing flight the model keeps up properly, but remains controllable for beginners. With a 4S battery, advanced players experience a noticeable performance increase: faster response, better climbing performance and a more sporty overall flight profile.

The jet remains easily controllable in all locations, the SAFE system reliably prevents critical flying conditions. Even deep over flights and narrow curves are easily executable in expert mode.

Transport capacity

The Habu STS has a clear span of approx. 1 meter and can be easily disassembled for transport. The assembly is designed in such a way that support surfaces and chassis can be separated from the hull without tools. The model can also comfortably accommodate smaller vehicles.

Spare parts supply and service

E-flite is known for its excellent spare parts supply. All relevant components for the STS Jet – from chassis components to wings to the entire fuselage – are available individually. Electronic components such as motor, controllers or servos can also be easily reordered. In case of warranty or technical problems, numerous specialist dealers and e-flite support are available.

Target group

This model is explicitly aimed at:

• Beginners, who want to make the first steps with a jet model with the support of flight assistance systems.
• Advanced pilots, who are looking for an uncomplicated, robust model for everyday operation – for practicing, relaxing flying or as a test platform for their own modifications.
• Flight instructors and clubs, as the SAFE system and the trainer mode provide ideal prerequisite for safe learning in groups.

Construction and Guidance

The assembly is well thought out and very easy to climb. Most components are preassembled on the factory. Typically, the setup takes less than an hour.

The high spread of the product ensures a large community – both online in forums and social media as well as locally in many model flight clubs. Exchange to settings, retrofitting and repairs is easily possible. Video tutorials and tutorials can be found in large numbers on relevant platforms.

Alternatives of competitors

If you are looking for an alternative, you will find different models with a similar orientation on the market:

*Some models can be retrofitted with Gyro system.

The Habu STS convinces by its uncompromising entry-level friendliness, which is specifically tailored to learning the jet flight. The alternatives usually lack a SAFE-like assistance system or the spare part supply is more restricted.

Price-performance

In comparison, the Habu STS offers an attractive price-performance ratio as a complete package with flight assistance, preassembled components and good spare parts supply. It should be emphasised that no further investment in assistance systems or complicated reconstructions is required. The quality and versatility justify the price, especially as security and ease of use – especially for beginners – are at a very high level.

Tips, tricks, recommendations and optimizations

• Use SAFE mode optimally: Beginners should start in the starter mode and then slowly switch to advanced and expert mode to be used step by step to agility and maneuvers.
• Battery selection: If you want longer flight times or more performance, you can upgrade to a 4S-LiPo (with appropriate weight and size). Take care of temperature development and telemetry.
• Optional landing sensor LAS: Unskilled pilots clearly benefit from the automatic flare function of the sensor, as this hard landing avoids and increases the longevity of the model.
• Check surface area: Before each flight ensure that surfaces and suspensions are correctly locked.
• Testing new settings: The control paths can be customized. Less rash is recommended for the first flights, larger rashes for sporty flying.
