FMS EDF Jets Explained — 64mm, 70mm, 80mm, 90mm and Twin EDF Buying Guide

FMS EDF jets sit in one of the most exciting parts of the RC aircraft hobby. They look like jets, sound different from propeller aircraft and offer a faster, more committed flying experience.

But an EDF jet is not usually the best first RC aircraft. These models reward pilots who already understand take-off, landing, orientation, throttle management and flying space. For beginners, an FMS trainer or civil aircraft is usually the safer first step.

This guide explains how to think about the FMS EDF jet range, including 64mm, 70mm, 80mm, 90mm and twin EDF aircraft, and how to choose between sport jets and scale military jets.

Quick Verdict

The best FMS EDF jet depends mainly on pilot experience, flying space and how much speed, scale detail and complexity you really want.

Best first EDF direction: 64mm EDF jets
Best balance of size and control: 70mm EDF jets
Best scale presence: 80mm EDF jets
Best advanced performance direction: 90mm EDF jets
Best for experienced pilots: twin EDF aircraft
Best learning path: trainer first, EDF second

If this is your first aircraft, start with an FMS beginner RC plane instead. If you already fly confidently and want the next step, EDF jets become much more interesting.

For the safer first-aircraft route, see the FMS Beginner RC Planes guide.

What Is an EDF Jet?

EDF means Electric Ducted Fan. Instead of an exposed propeller, the aircraft uses an electric fan inside a duct to create jet-style thrust.

This gives the aircraft a very different character from a trainer, bush plane or propeller-driven warbird. EDF jets often fly faster, need better throttle planning and usually require more attention during landing approaches.

They can look spectacular in the air, but they leave less room for lazy flying. That is why EDF buying should start with an honest question: are you ready for the speed and energy management, or are you mainly attracted by the look?

Why EDF Jets Are Not Usually First Planes

EDF jets are attractive because they look and sound closer to real jet aircraft than ordinary propeller models. That visual drama is exactly why many new buyers are tempted to start with one.

The problem is that EDF jets are usually less forgiving than true beginner aircraft. They often need more flying space, cleaner approaches, better speed awareness and more careful battery management.

A beginner trainer lets a new pilot build the basics first: orientation, throttle control, turns, take-off discipline, landing judgment and calm recovery from mistakes. Once those habits are in place, an EDF jet becomes a much better second or third aircraft.

64mm EDF Jets — The First EDF Step

The 64mm class is the natural starting point for many pilots moving into FMS EDF jets.

These models are usually more portable than larger EDF aircraft and can be a sensible transition for pilots who already fly propeller aircraft confidently. They still require respect, but they are less intimidating than large 80mm, 90mm or twin EDF models.

The FMS 64mm F-16 Fighting Falcon gives buyers a recognisable scale military jet shape in a more compact EDF format.

The FMS 64mm J-10 with Reflex V3 is another compact EDF direction for pilots who want a modern jet profile in a smaller package.

For a first EDF, many pilots should think carefully about visibility, wind, landing space and speed before choosing only by aircraft identity.

70mm EDF Jets — The Useful Middle Ground

The 70mm EDF class is one of the most useful middle-ground categories in the FMS jet range.

It offers more presence than compact EDF aircraft while still being more manageable than larger 80mm, 90mm or twin EDF models. For many pilots, this is where EDF flying starts to feel serious without becoming too large or specialised.

The FMS 70mm Viper V2 is a strong example of a sport jet direction. It is not chosen only for scale military realism, but for the flying experience.

The FMS 70mm Avanti V3 also sits in that sport-jet world, making sense for pilots who want a more performance-focused EDF platform without immediately jumping to the largest models.

For scale military appearance, models such as the FMS 70mm Yak-130 V2 and FMS 70mm F/A-18F Super Hornet V2 offer a different kind of appeal: more visual character, more aircraft identity and stronger scale presence.

80mm EDF Jets — More Presence, More Commitment

The 80mm class moves into a more serious EDF direction. These aircraft usually feel more substantial in the air and on the ground, but they also need more careful planning.

That planning includes transport, runway space, battery requirements, landing approach, parts support and pilot skill. Larger EDF jets can be more satisfying, but they are not casual impulse buys.

The FMS 80mm F-86 Sabre is a good example of why this class attracts scale aviation fans. It combines jet flying with a historic aircraft subject and stronger display presence.

The FMS 80mm Futura V3 is a more sport-focused alternative for pilots who want EDF performance without choosing a traditional military aircraft shape.

The FMS 80mm Rafale adds another scale military jet option for pilots who want stronger visual identity and more advanced aircraft presence.

This is where FMS EDF jets begin to cross over with the same kind of aviation interest that attracts people to model aircraft kits and die-cast aircraft.

For the static collecting side of aviation, see the Corgi Military Aircraft guide. For aircraft that are built, painted and weathered rather than flown, see the Airfix 1:48 aircraft kit guide.

90mm EDF Jets — Flagship Size and Advanced Flying

The 90mm class is a serious step up. These aircraft offer larger presence, stronger jet character and a more dramatic flying experience, but they also demand more from the pilot.

A 90mm EDF jet should be treated as an advanced RC aircraft purchase. It makes sense for pilots who already understand EDF behaviour, battery discipline, approach planning and flying field requirements.

The FMS 90mm Avanti 18th Anniversary Edition is a flagship sport-jet direction within the FMS EDF range.

The appeal is obvious: stronger sound, bigger visual presence, more dramatic passes and a more serious jet experience. But the ownership demands are also higher.

For most buyers, the sensible path is not to jump straight into the largest EDF jet. Build experience first, then move up.

Twin EDF Jets — Scale Drama for Experienced Pilots

Twin EDF aircraft add another level of complexity and scale appeal. They recreate the look and sound character of multi-engine jet aircraft, which can make them especially attractive to aviation fans.

The FMS Dual 70mm EDF SU-27 / J-11 is an example of this more serious twin EDF direction.

Twin EDF models should not be treated as beginner-friendly simply because some of them use 70mm fan units. The twin layout, size, speed, power system and field requirements make them better suited to pilots with established experience.

Sport Jets vs Scale Military Jets

One of the most important decisions in EDF buying is whether to choose a sport jet or a scale military jet.

Sport jets are usually designed around RC flying behaviour. They may be easier to read in the air, smoother in certain manoeuvres and more focused on predictable handling.

Scale military jets are chosen partly because of what they represent. F-16, F-86, Yak-130, Rafale, F/A-18 and other military subjects appeal to aviation fans because they look like real aircraft.

But scale appearance can bring more demanding handling, smaller wings, faster approaches or more complex details. The best choice depends on pilot maturity. If you want the smoothest first EDF experience, look carefully at sport jet options. If you are already confident and want the aircraft identity, a scale military jet becomes more attractive.

Reflex and Flight Assistance

Some FMS EDF models are associated with Reflex flight control support, depending on version and package. Flight assistance can help make EDF flying more approachable, especially for pilots transitioning from propeller aircraft.

But Reflex does not remove the need for skill. EDF jets still require proper take-off planning, landing approach discipline, enough space and good judgment in wind.

Use flight assistance as a support system, not as a replacement for practice.

What to Check Before Buying an FMS EDF Jet

Before buying any FMS EDF aircraft, check the exact product page carefully. EDF models are more sensitive to setup, battery choice and flight conditions than basic trainers.

fan size: 64mm, 70mm, 80mm, 90mm or twin EDF
completion level: RTF or PNP
required transmitter and receiver
recommended battery size, connector and discharge rating
charger compatibility
runway or launch requirements
landing gear and surface suitability
spare parts availability
pilot skill level

This is especially important because two aircraft in the same general category can have very different handling, equipment and field requirements.

Who Should Buy an FMS EDF Jet?

An FMS EDF jet makes sense for someone who already has RC aircraft experience and wants a faster, more dramatic and more jet-like flying experience.

It is especially suitable for:

pilots moving beyond trainer aircraft
aviation fans who want a flying jet-style model
RC pilots interested in speed and low passes
hobbyists who enjoy scale military aircraft
experienced pilots looking for larger and more serious aircraft

It is not the right first RC aircraft for most complete beginners. If you have never flown before, start with a trainer, learn the basics and return to EDF jets when your flying judgment is stronger.

Final Thoughts

FMS EDF jets are one of the most exciting parts of the FMS aircraft catalogue, but they should be chosen with honesty. The best EDF jet is not simply the fastest or largest model. It is the one that matches your flying experience, field, equipment and confidence.

The 64mm class is the most natural first EDF step. The 70mm class gives a useful balance of size and control. The 80mm class adds more presence and scale appeal. The 90mm and twin EDF categories are best reserved for experienced pilots with the space and skill to use them properly.

If you are ready, EDF flight can be a brilliant next step. If not, there is no shame in starting with a trainer first. The aircraft will still be there when you are ready.
