Overview
The E-flite® SE5a 900mm is the easiest to assemble, most capable, and fun to fly scale model of the iconic WWI fighter that's perfect for intermediate to experienced pilots. Once called the "Spitfire of World War One" and considered by many pilots to be the best British single-seat fighter of the time, the Royal Aircraft Factory (RAF) SE5 was instrumental in regaining and maintaining allied air superiority in mid-1917. It's one of the most recognisable aircraft of the era, and six manufacturers constructed more than 5000 examples. This BNF Basic model delivers unmatched scale detail, modern-day conveniences, features, and technologies whilst offering unexpected levels of flight performance that will satisfy demanding pilots.
Inspired by the original ParkZone model, this all-new design includes substantially more scale detail along with modern-day features and technologies to deliver an unmatched flying experience with surprising capabilities and performance. Whether you're a seasoned RC aircraft enthusiast or looking to expand your collection with a quality brushless RC plane UK pilots can rely on, this model offers something special. It bolts and snaps together in almost no time and is small enough to be easy to store and transport without disassembly – so it can be flown at large parks, sports fields, and dedicated RC flying sites throughout the UK. The compact 900mm wingspan makes this ready-to-fly RC aircraft a practical choice for flyers with limited storage space.
The BNF Basic version is equipped with enhanced AS3X+ technology that smooths out the effects of wind and turbulence better than ever before. It's also equipped with optional-use SAFE Select technology that makes it even easier to fly, whether you're refining your skills or simply enjoying relaxed recreational flying. All Spektrum digital metal-geared servos, a powerful 45-amp brushless ESC, and a specially tuned motor that works with both 3S and 4S batteries come factory-installed, meaning you're just a few snaps and bolts away from your first flight.

Technical Performance
The E-flite SE5a 900mm BNF Basic delivers impressive technical specifications that make it a capable performer in the hands of intermediate to experienced RC aircraft pilots. At the heart of this model is a Spektrum 3513-1100Kv 14-pole brushless outrunner motor delivering smooth, responsive power with excellent efficiency. The motor is paired with a Spektrum Avian 45-Amp Smart Lite brushless ESC featuring telemetry integration, which manages power delivery to the 10 x 5 propeller with precision. The model weighs just 1084 grams without a battery and 1303 grams with the recommended battery, making it light enough for responsive handling whilst maintaining structural integrity.
Battery compatibility is exceptionally flexible, supporting either 3S 11.1V or 4S 14.8V LiPo batteries in the 2200–3200mAh range, with both EC3 and IC3 connector options available. This flexibility means you can choose battery configurations that suit your flying style, with 3S batteries offering slightly longer flight times and 4S batteries delivering snappier performance. The Spektrum AR631+ 6-channel receiver with AS3X+ and SAFE Select ensures stable flight characteristics across a range of wind conditions, whilst the four digital metal-geared servos provide reliable, precise control inputs throughout the flight envelope. The centre of gravity is set at 72mm ± 5mm from the wing leading edge, a critical specification that ensures stable, predictable flight characteristics once the model is properly balanced with your chosen battery.
Dimensionally, the SE5a 900mm spans 899mm wing-tip to wing-tip and measures 716mm in length, proportions that deliver authentic scale appearance alongside practical flying characteristics. The EPO foam construction provides an excellent balance of weight and durability, allowing the model to absorb minor impacts whilst maintaining the precise weight distribution necessary for optimal aerodynamics. Flight performance benefits from the advanced AS3X+ stabilisation system, which provides a locked-in feel even in turbulent conditions whilst remaining optional for pilots who prefer unaided manual flight control.
