Test results: How does the sailor cut off?

Various specialist magazines and blogs have already tested Radian 2.0m. The reviews show the model excellent flight characteristics, great beginners and versatility in use. Above all, the AS3X stabilization, which effectively compensates for wind blows and makes the control behavior pleasantly calm. In the field of climbing and sliding flight, the model convinces with a powerful motorization and a very efficient wing.

Strengths in the test:

• Gentle thermal flights: Even light ups are used effortlessly.
• Uniform sliding behavior: The plane remains in the air without major corrections.
• Intuitive control: Even beginners can fly safely after a short get-together.

Review:

• Transport size: Despite two-piece wings, the sailor needs space in the car.
• Protection for landings: EPO foam is robust but not indestructible in rough terrain.

Material quality and processing

The Radian model series is known for its robust design from EPO foam. This ensures high resistance to small stops and makes the model relatively easy to repair. The plastic reinforcements and the solid bonding of the individual parts contribute to longevity. The factory-side assembly of the servos and control is particularly positive: cables and mechanical components are well protected and cleanly laid.

Flight times and battery selection

With the recommended 3S-LiPo between 1300 and 2200 mAh, the plane reaches flight times between 20 and 40 minutes. If you actively use Thermik and only use the engine to save, you can stay in the air with a battery charge. If desired, the drive switches to – for longer distances or for height recovery.

Increased performance and flight behaviour

The powerful brushless motor ensures impressive rises. Within a few seconds, the model is in safe altitude. Especially for Thermiksucher, it is a great advantage to be able to gain a lot of height with a little engine life. The aircraft glides very efficiently: Easy winds are enough to keep or win the altitude. In direct comparison, hardly any other foam model of this class offers a better climbing performance.

Transportability: Practical for travel

The wings of the Radian Sailer can be removed and divided without tools, which simplifies transport. For the way to the airport or to the holiday, the model can be brought to a handy package. The stable hull protects the technology well, an additional padding is recommended only for the supporting surfaces.

Spare part supply: Quick and easy

E-flite models benefit from a very good spare parts supply. Whether wings, guides, hulls or electronics – almost every component can be bought individually. Large retailers and online shops lead the most important components permanently in stock. Even after years, a repair is easily possible. Wear parts such as propellers and gears are also widely available.

Who is the model suitable for?

The “Radian BNF 2m” is ideal for the following target groups:

• Beginner: Thanks to SAFE Select stabilization, beginners are also very quick to learn.
• Advanced pilots: The thermal skills and the relaxed flight style make the model attractive for experienced enthusiasts.
• Restarter: If you return to the RC sky after a long break, you will find a simple and uncomplicated flight model.

Assembly & guidance: Quick and easy to understand

The aircraft is delivered pre-assembled almost in flight. Only the supporting surfaces and the height guide have to be fastened – this is possible in a few minutes and does not require a special tool. The German-speaking guide is clearly structured, richly illustrated and explains all steps comprehensible. The commissioning of the SAFE Select technology is also described in detail.

Real assembly time: Under 30 minutes, also for unskilled!

Community support: Help guaranteed

Alternatives of competitors: competition in view

If you are looking for alternatives, you will find in the middle price segment several models that differ in equipment and flight behaviour:

Multiplex EasyGlider 4

A classic among the foam spinners: Very robust, also with just 2 m span and similar beginners suitability. The EasyGlider models, however, are usually available as a kit or PNP version and often require more own effort during construction.

FMS Fox Glider 2,3m

The Fox Glider is a little bigger and offers an exceptional gliding performance. It has cross-wheels and therefore requires a little more flight experience.

H-King Bixler 3

A favorable entry model with excellent flight performances. Processing is somewhat simpler than with e-flite, but the price-performance ratio is correct.

Advantages of the Radian compared to alternatives

• Completely pre-assembled: Hardly own expense during construction.
• AS3X/SAFE Technology: Especially easy to climb.
• Very wide spare parts offer.

Value for money: Strong arguments

The price structure moves in the upper midfield, but offers very high equipment and value stability. The high material quality, modern electronics and excellent flying properties justify the price. In addition, the resale value remains stable as this sailing flight model is very popular.

Tips, tricks & recommendations from practice

Optimum battery selection

A powerful 3S lipo with approx. 2200 mAh offers the best ratio of flight time and weight. Low-cost batteries reduce costs, but occasionally reduce peak performance.

Place of departure

A large, windproof meadow is ideal. Trees and high obstacles should be avoided, as the model without a cross rudder is only limited.

Start and landing

Handstarts can best be done with light counterwind and medium engine thrust. A long-drawn gliding maneuver is recommended for landing.

Maintenance and maintenance

After each flight it is recommended to control the hinges and to improve any dents in the foam with hot water. The electronics should be regularly checked for a fixed seat.

Improvements/optimisations

• Carbon reinforcements on the surfaces increase the load capacity.
• Particularly stressed edges are additionally protected with the aid of adhesive tape.
• A quiet propeller can be exchanged for a high-quality folding propeller.

Sensual accessories

• Portable bag for protecting the surfaces.
• Replacement propeller and spider.
• Warning signal generator for battery voltage.

Popular questions & problems – and their solutions

1. How do I bind the recipient to my remote control?

Answer: The integrated AR636A receiver can be connected to any compatible spectrum DSMX/DSM2 remote control in binary mode. The guide describes this step by step – it is important to activate SAFE Select correctly if desired.

Two. Why does the engine sometimes not start?

Answer: Pay attention to the order when switching on: First transmitter, then model. Also check whether the gas lever is zero.

3. The model moves to the left/right when climbing – what to do?

Answer: Check the rudder trim and check the side rudder. The smallest adjustments on the servo can fix the problem.

4. The wing is damaged, what to do?

Answer: Small dents can be “sulled” with hot water. For larger cracks, UHU-Por helps, larger damage can be eliminated by replacement wings.

Five. How long does the foam last?

Answer: In proper use and storage, the material lasts many years. Direct sunlight should be avoided, as well as rough terrain.

6. I'm not getting up, how do I extend the flight time?

Answer: Reduce engine life and “circle” in Thermik. Fly at the right time of the day when the sun is getting up.

7. How can the model be transported more easily?

Answer: Remove both wing halves and disassemble the guides – so the aircraft also fits in small vehicles.
