Construction and Design

The E-flite-Product Family Nurflügler impresses with its sophisticated design that focuses on both performance and durability. The aerodynamic design with the specially developed wing profile allows a wide range of services - from rapid high-speed flights to controllable slow flights.

Material quality and processing

The model is made of light, yet robust EPO foam, which provides additional stability through strategically placed composite reinforcements. The design has been carefully optimized to provide a balanced balance between low weight and structural strength. The oversized Elevons are driven by digital servos with metal gears, ensuring precise control commands and excellent durability even in demanding flight maneuvers.

The processing quality corresponds to the high standard that can be expected from the E-flite brand. The clever three-part design, which significantly simplifies transport and storage, is particularly noteworthy. The connecting points between the wings and the central part are precisely manufactured and enable a secure connection without the use of tools or fastening elements.

Transport capacity

A special feature of F-27 Evolution is its innovative three-part design. With a span of nearly 40 inches (943mm), the only flew is quite space-consuming in assembled condition. Thanks to the intelligent design concept, however, the model can be disassembled into three parts without tools, which considerably simplifies transport and storage.

The wings are connected to the middle part via carbon fiber pipes and secured by a unique fastening system that comes out without screws or other fastening elements. This enables rapid assembly and disassembling at the field of flight, which is particularly advantageous for pilots with limited transport space. In the disassembled state, the F-27 needs significantly less space than comparable models of its class.

Performance and flight characteristics

Drive system and speed

The heart of the F-27 Evolution is its powerful drive system consisting of a 10-size Brushless external motor and a 40A Brushless controller. This setup offers impressive power reserves and allows different power levels depending on the battery used.

With a 3S LiPo battery, the Nurflügler already reaches respectable speeds of up to 85 km/h. If you want to exploit the full potential of the model, you can switch to a 4S LiPo battery, which ensures stunning acceleration, virtually unlimited rise and maximum speeds of up to 105 km/h.

This versatility allows the pilot to change in a single flight between different flight styles - from a fast high-speed flight reminiscent of a jet flyer to moderate cruising with the predictability of a sports model.

Increased power and agility

The combination of lightweight airframe and powerful drive system ensures an impressive rise. With a 4S LiPo battery, the F-27 Evolution shows an almost unlimited gradient. The overdimensioned Elevons in conjunction with the precise digital metal transmission servos allow stunning rolling rates and narrow curve radii.

The refined wing profile also allows a remarkably wide speed range. At low speeds, the model shows a good-natured flight behavior that will surprise even high-decker pilots. At full speed, the F-27 turns into an arrow-fast flyer that reacts precisely to control commands and offers an intense flight experience.

Flight times

The achievable flight times vary depending on the battery and flight style used. With a high-quality 3S LiPo battery with 2200-3000mAh capacity, flight times of about 8-12 minutes are possible if a mixed flight style is practiced with moderate speeds and occasional high-speed passages.

When using a 4S LiPo battery with a similar capacity, the flight time is shortened somewhat due to the higher power consumption, but offers significantly more power reserves. Typically 6-10 minutes are realistic, depending on the aggressivity of the flight style.

Pilots who value longer flight times should maintain a moderate flight style and adjust the gas position accordingly. The generous upper flap facilitates quick battery change, so that after a short break can be flown directly.

Target group and accessibility

E-flite F-27 Evolution focuses primarily on advanced RC pilots who have already gained experience with fast flight models. The high speed and agility of the Nurflügler require a certain amount of fingertip feeling and reaction capability, especially when the full power potential is exhausted with a 4S battery.

Thanks to the integrated AS3X technology (Artificial Stabilization - 3-Axis), however, the model offers a remarkable stability that compensates wind blows and other disturbing influences. This makes the flight more pleasant and precise even in non-optimistic weather conditions.

For beginners with first flight experiences, the optional SAFE Select function is a valuable tool. This can be activated to limit the flight movements and enable a safer flight experience. With activated SAFE Select, extreme flight positions are prevented, which reduces the risk of crashing and gives beginners more confidence.

Construction and preparation

Installation time and complexity

As a BNF (Bind-N-Fly) model, the F-27 Evolution is already largely pre-assembled to the customer. The basic assembly procedure is limited to connecting the three main components - middle part and two wings. This process usually takes no more than 10-15 minutes and does not require special tools.

The electronic components such as motor, controllers, servos and receivers are already installed and connected. The pilot must only bind a compatible spectrum transmitter to the preinstalled AR636A receiver, insert a suitable LiPo battery and can then begin flying.
