Key Takeaways
- EDF jets use an electric motor and ducted fan; turbine jets burn kerosene in a miniature jet engine.
- For most pilots approaching jets, EDF is the sensible next step, but a jet is not automatically a trainer.
- A first EDF setup needs a compatible radio, the specified LiPo battery and charger, and a suitable flying site.
- Turbines bring a much greater practical commitment: fuel handling, ground-support equipment, specialist safety procedures and club approval.
- Build your skills progressively, follow BMFA and club rules, and get advice from experienced pilots before moving up.
EDF vs turbine: what is actually producing the thrust?
Want the jet look without turbine-level complexity? Start by understanding what is happening inside the airframe.
An EDF, or electric ducted fan, uses an electric motor to spin a multi-blade fan inside a close-fitting duct. The fan accelerates air backwards; the reaction produces forward thrust: the force that pushes the model through the air. EDF models run from rechargeable LiPo (lithium-polymer) batteries, with an ESC (electronic speed controller) modulating the power sent to the motor.
A true turbine is different. It burns kerosene in a miniature gas-turbine engine, where hot gases drive a turbine and produce the jet exhaust. That brings the characteristic turbine sound and substantial thrust, but also a fuel system, starting procedures, hot exhaust and additional ground support.
EDF systems range from small micro models with 30mm fans to larger models with 90mm or bigger fans. Fan diameter helps describe the power-system format, but it does not tell you by itself whether a model is beginner-friendly. Airframe design, weight, speed, control response and the pilot’s experience all matter.
You may also see KV in motor specifications. It is the motor’s approximate no-load revolutions per minute per volt; it is not a direct measure of how fast the complete aircraft will fly. The installed fan, battery, ESC and airframe all affect the result.

What does your first EDF jet need?
Already comfortable flying a conventional plane? Then an EDF can be a rewarding next move. If you are new to fixed-wing flying, learn the basics on a suitable trainer first. A swept-wing jet can carry speed, lose energy quickly in a turn and offer less warning when flying slowly. Stabilisation helps, but it does not replace piloting skill.
Before choosing a model, check that you have:
- A compatible transmitter. “Compatible” means the radio protocol and channel requirements match the receiver and model.
- The specified LiPo battery. Match the cell count, capacity and connector recommended for that aircraft; a mismatched battery can harm performance or damage components.
- A compatible LiPo charger. Use the correct charging mode and follow the battery and charger manufacturers’ safety instructions.
- A suitable flying site. Choose an open area where the model can be flown legally and safely, and where the site rules allow powered models.
- A pre-flight routine. Check control direction, servo movement, battery security, fan and airframe condition, and radio failsafe before each flight.
A BNF Basic model means “Bind-N-Fly Basic”: the model comes with its receiver and power system installed, but you still need a compatible transmitter, battery and charger. AS3X+ is flight-stabilisation technology that counteracts unwanted movement, such as turbulence. SAFE Select adds optional flight-envelope protection and level-flight recovery assistance. These features can provide a useful extra margin while you learn a particular model, but they cannot correct poor site choice, rushed setup or a manoeuvre beyond your ability.
Pro tip: Read the product page’s skill-level and completion requirements before treating a model as a first jet. The E-flite Viper 64mm BNF Basic is a useful example of a BNF Basic jet with AS3X+ and SAFE Select, but AT Models lists it as advanced. Think of it as a step-up option for a pilot with suitable fixed-wing experience, not a first-ever aircraft.
A compact EDF pick
The E-flite UMX F-86 Sabre 30mm EDF is a small BNF Basic model with AS3X and SAFE technology. Its compact size makes it easier to transport than a larger jet, but that does not make it a trainer or suitable for every field. Check the model’s battery, transmitter and flying-site requirements, and treat any flight as a proper flight, not a casual test close to people, buildings or roads.
A micro EDF can make a short local flying session more practical when you have an appropriate, permitted open area. “Small” does not mean “safe to fly on the doorstep.”
How to progress through EDF models
Do you need to jump straight to a twin fan or a large jet? No. A gradual progression lets you learn how your aircraft responds to throttle, speed and control inputs before adding more complexity.
A sound route is:
- Learn fixed-wing basics on an appropriate trainer, building reliable take-off, circuit, approach and landing habits.
- Move to a manageable EDF once you can confidently control a conventional model and judge its approach speed.
- Broaden your jet experience with more demanding EDF layouts only when your current model feels familiar and well within your control.
- Consider turbine airframes later, after gaining experience with fast models and understanding the extra setup and safety requirements.
PNP means “plug and play”: major components are fitted, but you generally need to supply a compatible receiver and radio equipment, battery and charger, and complete the model-specific setup. Always check the exact product page; the details vary by model. Installed servos, the small actuators that move control surfaces, do not mean every other component is included.
A twin-fan EDF to explore
The XFly F-22 Twin 40mm EDF Jet is an example of a twin-fan EDF format. AT Models lists it as an advanced model, so it is better viewed as an option for a pilot with experience, not as a shortcut into jet flying. Check the listing for its assembly and radio requirements before choosing it.
What does stepping up to a turbine involve?
Is a turbine just a louder EDF? Definitely not. It is a complete operating system built around a kerosene-burning engine.
AT Models stocks Enjet E130 and E170 turbine engines. Their product pages specify 13kg and 17kg of thrust respectively. Here, thrust describes the engine’s pushing force; the right engine must be selected for the airframe and its manufacturer’s requirements, not chosen by thrust figure alone.
A turbine commitment includes more than installing an engine. Expect to learn the complete fuel and control arrangement, follow the engine maker’s start-up and maintenance instructions, and provide suitable ground support for safe operation. Turbines also produce very hot exhaust and require disciplined procedures around starting, running and shutting down.
That is why turbine flying is for experienced pilots who have appropriate club support and meet the site’s requirements. Do not treat purchasing a turbine-ready model as permission or preparation to fly one.
A turbine airframe example
The HSD F-16 6kg turbine foam jet PNP is supplied without a turbine and is intended for experienced turbine pilots. Its listing specifies a suitable turbine class and additional equipment required to complete it. Read those requirements carefully, and discuss the model with knowledgeable turbine flyers at your club before planning a build.
Safety and where to fly
Where should you fly a jet? At a site that is suitable for the aircraft and where you have checked the current rules. Do not assume a field is appropriate because a model is small, electric or easy to transport.
- Follow BMFA guidance, applicable aviation rules and the flying site’s own procedures.
- Check whether the club has extra requirements for EDFs, turbines, engine runs or pilot competency.
- Keep people and loose items clear of an EDF fan, especially when connecting a flight battery or testing the power system.
- Handle and charge LiPo batteries exactly as their manufacturer instructs; stop using a pack that appears damaged.
- For turbine operation, follow engine-manufacturer instructions and club procedures for fuel, starting, shut-down and safe separation.
- If you are unsure about your experience level or model choice, talk to experienced fixed-wing and jet pilots before flying.
The BMFA RC Jets guidance and BMFA getting-started information are useful places to begin. Your club’s rules remain essential: they may set requirements beyond general guidance.
Key Takeaways
- EDF is electric; turbine is kerosene-powered. They share the jet shape, not the same operating demands.
- Learn on a conventional trainer, then progress to an EDF that suits your experience and flying site.
- Check battery, transmitter, receiver and charger compatibility before completing any model.
- SAFE Select and AS3X+ support the pilot; they do not replace skill or safety checks.
- Treat turbines as a later step requiring experienced pilots, thorough preparation and club approval.
Choose a sensible first step, keep asking questions as your skills develop, and you can discover the world of RC jets with confidence, then soar to new heights when you are ready.
