Overview
The E-flite Beechcraft D18/RC-45J 1.5m BNF Basic with AS3X+ and SAFE Select represents a remarkable return of one of the most beloved and highly-rated scale RC aircraft ever produced. This is a genuine aviation icon brought to life as a ready-to-fly RC model, specifically designed for pilots who have some RC flying experience and want to enjoy authentic, feature-rich scale flying without the complexity of building from scratch. The Beechcraft D18, also known as the Twin Beech, was adapted into 32 different versions by Beechcraft Aircraft Corporation, with over 9,000 total aircraft produced between 1937 and 1969, serving as everything from passenger transports to military trainers. Now this classic is available as a fully painted, comprehensively equipped brushless RC aircraft that combines authentic scale detailing with practical, easy-to-use flight technologies that make it accessible to intermediate pilots.
What sets this particular model apart is its exceptional engineering and thoughtful design philosophy. The BNF Basic version comes almost completely ready to go straight out of the box—all you need is a compatible Spektrum transmitter, a LiPo battery, and a charger to be flying. The factory-installed systems include twin brushless motors with counter-rotating propellers, a sophisticated Spektrum Avian Dual 40-Amp Smart Lite ESC, and the intelligent AR631+ receiver loaded with advanced AS3X+ and optional SAFE Select technologies. Whether you're an experienced RC flyer looking for a versatile scale model or someone seeking the best brushless RC aircraft UK retailers have to offer, this aircraft delivers exceptional value and capability.
The D18/RC-45J features a striking military finish inspired by a US Navy variant that served as a navigation trainer before being reconfigured as a photo reconnaissance trainer in the 1950s.

This rating reflects the size of the aircraft, the number of systems to manage in flight, and the importance of solid fundamental RC piloting skills. However, the addition of AS3X+ and optional SAFE Select technologies makes this aircraft considerably more forgiving than earlier D18 variants, allowing competent intermediate pilots to focus on enjoying the flying experience rather than fighting the aircraft. If you are a true beginner with minimal RC flying experience, this model is not recommended—you would benefit from first flying a smaller, simpler Skill Level 1 aircraft to develop basic control inputs, trim management, and situational awareness before progressing to this sophisticated twin-engine scale model.
Frequently Asked Questions
- What makes the Beechcraft D18/RC-45J suitable for intermediate RC pilots? — This aircraft combines a large, impressive scale appearance with sophisticated stability systems that make it more forgiving than pure aerobatic models. The AS3X+ system automatically compensates for wind and turbulence, whilst SAFE Select can be toggled on to provide bank angle and pitch limits if you need additional assistance. The twin-engine configuration with counter-rotating props eliminates torque roll tendencies, and the docile 3S configuration allows for leisurely scale flying. If you have experience with similar 1.3–1.5m models, you'll find this aircraft intuitive and enjoyable.
- How long will the battery last per flight? — Flight time varies significantly based on your chosen battery capacity and flying style. With a 3S 3200mAh battery flown in scale-like fashion, expect 15–20 minutes of flight time. Larger 4500–5000mAh 3S batteries can extend this to 25–30 minutes. With 4S power and aggressive flying, flight times typically range from 12–18 minutes. Installing two 2200mAh batteries in parallel provides excellent flight duration with 3S power.
- What is the difference between 3S and 4S battery operation? — On 3S batteries (11.1V), the aircraft delivers scale-like performance with excellent flight times and gentle, predictable handling—ideal for leisurely flying, photography, and enjoying the scale realism. On 4S batteries (14.8V), the power increases significantly, delivering faster speeds, unlimited vertical performance, and more spirited aerobatic capability without any modifications required. Many pilots keep multiple batteries in different configurations to suit different flying moods and mission profiles.
- Is the Spektrum AR631+ receiver compatible with all Spektrum transmitters? — The receiver features full-range 2.4GHz DSMX compatibility, meaning it will bind to any Spektrum transmitter from entry-level 6-channel models (DXS, DX6e) through professional 14-channel systems (iX20, NX20). All Spektrum transmitters from the last decade are compatible. If you own an older DSM2 transmitter, compatibility is also supported, though DSMX is preferred for enhanced range and security.
- What does the Smart Transmitter File feature do? — When binding an STF-equipped receiver to NX or iX series Spektrum transmitters, the receiver automatically downloads all programming parameters including switch assignments, control rates, exponential curves, telemetry settings, and voice callouts—eliminating hours of manual programming and allowing you to begin flying within minutes of binding.
- Can I fly this aircraft from grass fields? — Yes. The factory-installed electric retracts feature durable metal components and are specifically designed to support operations from grass, packed dirt, and paved surfaces. Many pilots regularly operate the D18/RC-45J from unimproved grass strips, adding another dimension to the scale flying experience.
- What is AS3X+ technology and how does it help? — AS3X+ (Artificial Stability & Gyro) is a stabilisation algorithm that runs continuously in the aircraft's receiver, filtering out the effects of wind gusts and turbulence. Rather than fighting constant small wind disturbances, your control inputs are smoothed and the aircraft maintains a stable, locked-in feel that makes it respond as though it were significantly larger and more stable. This is especially valuable in gusty conditions or when flying at distance where turbulence effects are more pronounced.
- Can SAFE Select be disabled if I don't want it? — Absolutely. SAFE Select is entirely optional and can be disabled by simply binding the receiver normally to your transmitter without enabling the SAFE features. If you later decide you want the protective flight envelope, you can rebind and activate it—there's no penalty for leaving it off if you prefer to fly without it.
- What makes the Beechcraft D18 historically significant? — The full-size Beechcraft D18 Twin Beech was in production from 1937 to 1969 and became one of general aviation's most successful and recognisable aircraft. Beechcraft produced 32 different versions, with over 9,000 aircraft built. They served in countless roles including passenger transport, mail delivery, military training (navigation and bombardier instruction), and photo reconnaissance. The US Navy variant represented by this RC model served as both a navigation trainer and photo reconnaissance trainer, making it a genuine piece of aviation history brought to life in RC form.
- How does differential thrust improve handling? — Differential thrust allows the two motors to run at slightly different speeds, with the outer motor providing more thrust on turns to improve ground handling and reduce the adverse yaw effects that twin-engine aircraft naturally produce. This makes taxiing more natural, takeoffs more controllable, and enables specialized aerobatic maneuvers. The feature is factory-programmed and works automatically with compatible Spektrum AirWare transmitters including the DX6e, DX8e, NX series, and iX series.
- What is the difference between BNF Basic and other Beechcraft D18 versions? — BNF Basic means Bind-N-Fly with essential systems—the aircraft arrives with all motors, ESC, servos, and receiver installed, but you provide the transmitter, battery, and charger. The BNF Basic variant is the only D18/RC-45J model equipped with the advanced AR631+ receiver featuring AS3X+ and SAFE Select technologies, making it the most feature-rich and easiest-to-fly version available.
- How many channels do I need on my transmitter? — The AR631+ receiver provides 6 channels, which are assigned to: Aileron, Elevator, Throttle, Rudder, Flaps, and Gear. You need a minimum 6-channel transmitter, though 7+ channel models offer additional flexibility for future expansion. Any full-range Spektrum DSMX transmitter with 6 or more channels will work perfectly.
- Is assembly really as quick as advertised? — With everything pre-installed and no glue required, you can indeed have the aircraft ready to fly in 30–60 minutes depending on your familiarity with RC models. The main assembly tasks involve connecting the three-piece wing using hands-free quick-connect mechanisms, installing the battery, and binding the receiver to your transmitter. Most experienced RC pilots accomplish this in under an hour.
