General technical data and facts

A precise overview of all relevant specifications supports the purchasing decision. The following technical data is the basis for the flight experience:

Customer reviews and experiences

There are a number of positive feedbacks in the network that illuminate various aspects. The majority of users highlight the elegant optics, thermal behavior and impressive climbing performance. Especially beginners and advanced pilots appreciate easy handling while at the same time high development potential.

Highlights from customer reviews:

• Excellent flying properties, especially when circles in the Thermik.
• The assembly is perceived as uncomplicated; “packing out, few handles and already it can go off”.
• The disturbing flaps allow a precise landing, which is often called a large plus point.
• The robust materials provide protection against major damage even with less optimal landings.
• There is sometimes some criticism of the work-side focus that should be customized.

Many users stress that even after several flights, no significant wear phenomena occur. The model is called “perfect for the evening flight” or “ideal weekend equipment”.

Test results and test reports

Technical journals and independent model builders certify the Radian XL version very good flight performances. The design on thermal and route flight is just as appreciated as the high stiffness of the support surfaces despite the foam material.

Summary of the test reports:

• Very good thermal performance, even with weak winds, the model is reliable.
• Pleasant flight picture – majestic circles through the generous surface depth.
• The control of the large flaps is praised as decisive for precise landings.
• The ease of assembly and prefabrication enable quick commissioning.
• The combination of strong drive and light weight convinces when starting up by motor.

Occasionally it is noted that the model reacts sensitively to strong thermals and should then be flown with ballast to calm the flight situation.

Material quality

The aircraft consists predominantly of robust Z-foam, which is not only lightweight but also durable. Compared to traditional Balsa models, the material convinces with ease of repair and breaking strength. The surfaces are reinforced by carbon fiber spars, which guarantees a very good torsional stiffness for a model of this size. Damage, for example after hard landings, can usually be easily repaired with second glue or foam polish.

Model flight times

The flight time depends significantly on the battery capacity used and the flight mode:

• With a 3S LiPo battery (approximately 3200 mAh), flight times of 45 to 60 minutes are absolutely realistic – with predominantly sailing operation and economical motor use.
• If you are actively looking for Thermik and using the engine to climb, you will fully exploit the power potential.
• In the pure motor cycle flight the flight time is reduced, but the concept of the model is mainly designed for sailing flight.

Increased performance and flight behaviour

The built-in Brushless Outrunner engine ensures a rapid rise. Practical values of many users show that after a few seconds, engine speeds of 150 meters and more are reached. The rise rate is about 4-5 meters per second – a very good value for a model of this category.

In the sailing flight, the aircraft convinces with stable glide characteristics, but reacts directly to control commands. The transverse rods and the generous wing span ensure smooth introduction of curves and precise deflection in the thermal system.

Transportability and handling

The transport of the sailor is made easy by the divided supporting surfaces and the compact hull shape. The support surfaces can be removed in a few steps and stored in the trunk of a standard car. The model with matching backpack or suitcase protection is also suitable for transport to the fly meadow by bicycle or in the ÖPNV.

Spare parts supply

The supply of spare parts is very good in this model due to the widespread distribution in the European market. Almost all assemblies – from surface to servos or motor – are available as individual parts. This guarantees long-lasting flying pleasure, even if repairs are due after an accident.

Target group of the E-flite Radian XL 2.6m

The model is primarily aimed at:

• Advanced beginners who already have basic knowledge of sailing.
• Thermal and track flyers that value robust, everyday designs.
• Pilots who want to spend little time on complex construction measures.

Advanced model flyers also appreciate the potential for their own modifications and the possibility to create an individual setup with the high-quality basic equipment.

Construction time and instructions

Depending on the experience, the assembly time is between 30 and 60 minutes. The construction instructions are clear, available in several languages and guides graphically and textfully through the individual assembly steps. All connection points are accurate, the wiring of the electronics is preassembled. Only the mounting of the support surfaces, the height control unit and the battery and the binding of the receiver are to be carried out. The guide also explains the correct setting of center of gravity and rudder deflections.

Community support

The popularity of the model is also reflected in an active community. In numerous internet forums, social media and YouTube channels there are tips, construction videos and flight reports. Exchange to modifications and repair instructions is also widespread. Newcomers will quickly find support, whether it is the focus, choice of the battery or improvements.

Compared to alternative products from other manufacturers

In the 2.6 to 3 meters range, well-known competitors offer some sailplanes that have their own advantages and disadvantages. A comparison facilitates the classification of the E-flite Radian XL 2.6 meter sailor:

Conclusion for comparison:
The E-flite Radian XL 2.6m is positioned in the upper class of the foam glider with regard to load capacity, flight performance and processing. The main competitors often offer less rigidity or less equipment. The special feature of the model is the harmonious overall package for thermal lovers and open-air semi-trailers.

Value for money

Compared to the competition, the purchase price moves in the upper midfield. For money, buyers receive a very well-equipped sailing model that brings high-quality components, best flight characteristics and first-class materials. Spare parts and accessories are not cheap but fairly calculated.

Tips, tricks, recommendations and optimizations

Focus on measuring:
Many pilots recommend to optimize the focus individually after their own loading and, if necessary, to adjust it slightly with lead weights. This improves the curve properties and reduces the risk of overlay maneuvering.

Better propeller selection:
If you want maximum climbing performance, you can switch to a high-quality folding propeller. This increases the efficiency of the drive and saves power.

fine-tuning rudder paths:
The work-side deflections of the transverse elements and disturbing flaps are selected conservatively. For experienced pilots it is recommended to make the model more agile.

Optimize battery compartment:
With an inlay base made of plywood or CFRP, the battery compartment for large LiPo batteries can be adapted and thus the flight time can be increased again.

Secure wing connection:
For rough flight days it may be useful to secure the wing connection with an additional tape or rubber band.

Training start and landing technology:
Due to the low sink rate, the landing approach is extended. With retracted flaps and slightly raised guide, the model lands particularly gently.

Frequent questions and problems with solutions

1. Engine does not run/electronics does not react:
Check the polarity and cabling of the battery. The receiver must be correctly bound and the transmitter must work in the DSMX mode.

Two. Focus is too far behind (unstable flight behaviour):
focus with small lead weights in the battery compartment or at the hull tip to the front; this improves the goodness.

3. Loading surface loosens in hard landings:
fixing the surfaces with additional tape or connecting pins; Check the plug connection before each flight.

4. Flight times too short:
Choose larger battery (e.g. instead of 3S 3200 a 3S 5000 mAh), otherwise check the folding propeller for efficiency.

Five. Distinguishing power:
Check the propeller blades and exchange them for high-quality specimens. Also check the condition of the battery.

6. Spare parts difficult to find:
Use official dealers such as Horizon Hobby and larger model shop – many parts are online storage.

7. Incomprehensible instructions:
Online communities and vendor sites often offer complementary videos and image sections that help.

8. Model difficult to transport:
Acquisition of a transport bag or a wingsaver made of foam is recommended for travellers.

What buyers also want to know: questions and answers

• Can the model be flown in winter at low temperatures?
  Yes, the Z-foam is stable even in cold, but batteries should be preheated.

• Is the recipient included?
  A compatible receiver is integrated with the BNF Basic set; a spectrum remote control system is required.

• How large is the movement space of the transverse rods?
  Limited to about 15° on the work side, but can be arbitrarily extended via the transmitter.

• What minimum area is needed for a safe start?
  A stray or a small sports field is sufficient, as the sailor is not a ground start model.
