FMS RC Airplane Parts Explained — Fuselages, Wings, Landing Gear, Motors, EDFs and Repair Spares

FMS four-blade RC airplane replacement propeller with black blades and yellow tips

An RC airplane does not have to become a write-off because of one damaged wing, cracked fuselage, bent landing gear or failed electronic component. One of the strongest parts of the FMS ecosystem is the depth of official replacement parts available for individual aircraft, from small trainers to large warbirds and high-performance EDF jets.

FMS sells complete fuselages, main wings, horizontal stabilisers, landing gear assemblies, retracts, motors, ESCs, servos, EDF units, propellers, spinners, wheels, floats, cockpit parts, linkage hardware and many smaller airframe components.

That matters both when repairing crash damage and when keeping an older aircraft flying after individual components begin to wear.

The key is compatibility. FMS parts are frequently designed around a specific aircraft, wingspan and generation, so the model name alone is not always enough. A part intended for one version of a P-51, Ranger, PA-18 or EDF jet should not automatically be assumed to fit another.

Why FMS RC Airplane Parts Availability Matters

Foam RC airplanes are designed to fly, not remain permanently on a shelf. That means accidents and wear are part of the hobby.

A hard landing can damage the landing gear without harming the airframe. A wingtip can suffer while the fuselage remains intact. A propeller can break during a nose-over. Servos and ESCs can eventually need replacement even when the aircraft itself still looks excellent.

Being able to replace one damaged assembly rather than an entire airplane changes the economics of ownership considerably.

This is particularly important for beginner aircraft. Early flying inevitably involves imperfect approaches, bounced landings and occasional mistakes. A trainer backed by a strong spare-parts catalogue can remain useful long after the first accident.

For pilots choosing a first aircraft with repairability in mind, FMS Beginner RC Planes Explained — What to Buy First for Your First Flights looks at trainer options, flying space, Reflex support and the importance of spare-parts availability before buying.

The same principle becomes even more important with larger or more expensive models. Replacing a wing, retract or fuselage is usually much more sensible than treating a damaged aircraft as disposable.

Start with the FMS Part Finder

The safest way to search for FMS replacement airplane parts is not to begin with a generic component name.

Begin with the exact aircraft.

FMS provides a Part Finder that organises replacement parts around individual models, covering beginner aircraft, warbirds, EDF jets, aerobatic aircraft, gliders and other platforms.

This approach reduces one of the most common problems when buying RC airplane spares: finding something that looks correct but belongs to a different generation, wingspan or airframe.

For example, several aircraft families have existed in multiple versions. Landing gear geometry, connectors, servo wire lengths, wing mounts and fuselage mouldings can change between revisions.

The model-specific parts pages are therefore one of the most useful sections of the FMS website.

FMS Replacement Fuselages

A damaged fuselage can look like the end of an aircraft, but FMS sells replacement fuselage sections for a wide range of models.

The dedicated fuselage collection covers trainers, civil aircraft, warbirds and EDF jets.

Examples include PA-18 Super Cub fuselage sections, Cessna 182 fuselages, Ranger bodies, P-51 Mustang fuselages and replacement structures for aircraft such as the F-16, F-86, Futura and Avanti.

Some aircraft use a single replacement fuselage assembly, while others divide the airframe into front and rear sections. The 1300mm PA-18, for example, has separate front and rear fuselage components listed by FMS.

This can make a major repair far more economical if the wings, electronics and landing system survived the original damage.

Browse FMS RC Airplane Replacement Fuselages

Replacement Wings and Main Wing Sets

Wings are another major structural component that FMS sells separately across many aircraft families.

Replacement main wing sets can be especially useful after a heavy tip strike, failed landing, transportation accident or damage around the landing-gear mounting area.

Depending on the model, a wing assembly may include control surfaces, mounting hardware or other installed components, but the exact contents should always be checked on the individual product page.

FMS lists wing sets for aircraft ranging from trainers such as the PA-18 and Ranger to warbirds such as the P-40, P-47, Zero and Corsair, as well as EDF aircraft including the F-16, F/A-18 and Futura.

This is also why buying by wingspan and exact aircraft version matters. An 800mm aircraft and a 1400mm version of the same full-size subject are completely different RC platforms.

Horizontal Stabilisers, Tail Sections and Control Surfaces

Not every airframe repair requires a complete wing or fuselage.

FMS also lists horizontal stabilisers, tail components and related hardware for many aircraft.

These parts can be particularly useful after hangar damage or transportation accidents, where a tail surface may be broken even though the rest of the aircraft never left the ground.

Control horns, linkage rods, wing pipes, braces, struts and mounting pieces also appear throughout the FMS parts ecosystem.

Small pieces can be inexpensive compared with complete assemblies, so identifying the actual failed component before ordering can save both money and unnecessary disassembly.

Landing Gear, Wheels and Retracts

Landing systems are among the most vulnerable parts of an RC airplane.

A landing that is only slightly too hard can bend a leg, damage a wheel or stress a mounting point while leaving the rest of the aircraft completely usable.

FMS lists conventional landing gear components, wheel sets, electronic retract systems and aircraft-specific landing assemblies.

The difference matters.

A trainer with fixed landing gear may need little more than a replacement wheel, spring, bracket or gear assembly. A scale warbird or EDF jet may use retractable landing gear with dedicated electronic retract units and more complex mounting hardware.

For example, the FMS P-40B parts catalogue includes both a main landing gear set and electronic retract components, while aircraft such as the F/A-18 also have separate front and main landing gear assemblies.

Before buying a replacement, check whether the damaged component is the wheel, strut, retract mechanism, mounting hardware or complete gear assembly.

Propellers and Spinners

Propellers are one of the easiest RC airplane components to damage and one of the most sensible spares to keep available.

A simple nose-over on grass can break or distort a propeller even when nothing else is damaged.

FMS sells many aircraft-specific propellers as well as common propellers shared by several models.

The size printed on the propeller matters. Diameter, pitch, blade count and aircraft compatibility affect both motor loading and flight performance, so choosing a propeller simply because it physically fits the shaft is not a good approach.

For example, FMS lists an 11x7 propeller for aircraft including the 1400mm J-3 Cub V4, 1400mm Kingfisher, 1300mm PA-18 and 1500mm Maule, while other warbirds and compact aircraft use completely different propeller sizes.

Spinners are also available separately for many models and are worth checking after any nose-first impact.

Browse FMS Propellers, Spinners and Airplane Parts

Motors and Motor Mounts

The electric motor is another part that can often be replaced without changing the rest of the power system.

FMS lists a substantial range of motors across its airplane catalogue, covering small trainers, large propeller aircraft and other platforms.

Motor mounts and motor boards are also sold separately for selected models.

This distinction becomes important after a propeller strike. The motor itself may remain functional while the mount or board behind it is damaged.

Replacing only the failed component is usually preferable to changing a complete power system unnecessarily.

Motor specification also needs to match the intended aircraft. KV rating, physical dimensions, shaft arrangement, battery voltage and propeller load are all part of the original power-system design.

For a straightforward repair, the safest route is usually the original FMS replacement specified for the exact airframe.

ESCs and BECs

Electronic speed controllers regulate power between the battery and motor, and FMS stocks aircraft-specific ESC and BEC components across many model ranges.

Replacing an ESC is not simply a question of selecting something with wires that fit.

Current rating, battery voltage, connector type, BEC output and the requirements of the motor and servos all matter.

A replacement with insufficient capacity can create reliability problems, while changing connectors or specifications without understanding the complete electrical system can introduce unnecessary complications.

When restoring an otherwise stock FMS aircraft, matching the original specification is generally the simplest route.

Servos and Linkage Components

Servos operate the control surfaces that keep an aircraft controllable in flight.

FMS stocks digital servos in different sizes, directions and wire lengths, as well as linkage rods and associated control hardware.

Two servos that appear externally identical may not necessarily be interchangeable.

Rotation direction, travel, lead length, mounting dimensions and the control surface being driven can all matter.

This is another area where the model-specific Part Finder is preferable to buying by appearance alone.

Linkage rods, control horns and connectors deserve the same attention. A damaged control linkage may be a very small part, but it can have a major effect on safe control of the aircraft.

EDF Units, Fan Blades and Jet-Specific Parts

FMS EDF jets introduce another layer of replacement components because propulsion is based on an electric ducted fan rather than an external propeller.

The FMS catalogue includes complete EDF units, motors and individual fan-related components for selected aircraft.

A model such as the 64mm F/A-18 demonstrates how extensive the support can become. FMS lists the fuselage, main wing set, cockpit, front and main landing gear, servos, missile components, exhaust parts and a 64mm ducted-fan assembly within the same aircraft ecosystem.

That is particularly valuable for EDF pilots because a damaged airframe does not automatically require replacing the expensive propulsion system — and a propulsion problem does not necessarily require replacing the complete aircraft.

EDF diameter and motor specification must match the intended aircraft and power system. A 64mm unit should not be treated as interchangeable with larger 70mm, 80mm or 90mm installations simply because all are electric ducted fans.

For the aircraft side of that decision, FMS EDF Jets Explained — 64mm, 70mm, 80mm, 90mm and Twin EDF Buying Guide compares the main FMS EDF classes, flying requirements and progression from smaller jets to larger systems.

FMS Reflex Flight Controllers

The FMS Reflex system sits slightly differently from conventional replacement hardware.

Reflex is a flight-stabilisation system used across numerous FMS aircraft, particularly useful for pilots who want additional assistance during learning or more stable flight characteristics in difficult conditions.

Replacement or additional Reflex hardware appears in the wider FMS aircraft accessory catalogue.

Compatibility and configuration should be confirmed before installation, especially when moving electronics between aircraft rather than simply replacing the unit in the model for which it was originally configured.

Browse FMS Reflex and RC Airplane Accessories

Batteries, Chargers and Power Accessories

Batteries and chargers are consumable parts of RC flying in a way that a fuselage or wing is not.

LiPo batteries gradually age through use, storage and charging cycles, while pilots often buy additional packs simply to increase flying time at the field.

FMS lists aircraft batteries in several capacities and voltages alongside chargers and battery-checking equipment.

The correct battery is not determined by capacity alone.

Cell count, voltage, connector, discharge capability, physical size and weight all affect compatibility and aircraft balance.

A battery that is electrically capable of powering an aircraft may still be unsuitable if it changes the centre of gravity or does not fit securely in the battery compartment.

Floats and Water-Flying Conversions

Some FMS aircraft can be converted from conventional land operation to water flying through optional float sets.

The broader airplane-parts catalogue includes float components for compatible aircraft.

Models such as the PA-18, Ranger and other utility-style aircraft are particularly well suited to this kind of conversion when the specific airframe supports it.

Floats should be treated as aircraft-specific equipment rather than generic accessories. Mounting geometry, aircraft balance and water-handling requirements all matter.

Browse FMS Floats and RC Airplane Accessories

Cockpits, Pilots, Cowls and Scale Details

Not every replacement part exists because something affects flight performance.

FMS aircraft often include scale components such as pilot figures, cockpit assemblies, cowls, exhaust parts, antennae, air grills, lamp covers, guns and other visual details.

These components are especially relevant to warbirds and scale jets, where a missing cockpit part or damaged cowl can spoil the appearance of an otherwise perfectly flyable aircraft.

The availability of smaller visual components also creates opportunities for restoration. A used FMS aircraft with intact structure but missing scale details can sometimes be brought much closer to its original appearance without replacing major assemblies.

Screws, Connectors, Linkages and Small Hardware

The least glamorous parts can sometimes be the ones that keep an aircraft grounded.

FMS model-specific parts pages include screw sets, multi-connectors, linkage rods, wing mounts, motor boards, battery trays, brackets and other small hardware.

These components are easy to overlook when searching only for major categories such as wings or fuselages.

They are also one of the strongest reasons to search by the exact aircraft rather than browse a generic parts list.

A specialised connector or mounting bracket may cost little compared with a complete airframe, yet it can be essential to putting the aircraft back into service.

RC Plane Tools, Glue and Workshop Equipment

Replacement parts solve one side of a repair. Installation requires the right tools and materials.

FMS also maintains an RC Plane Tools section with products such as foam glue, epoxy, lighting components, stands and workshop-related accessories.

Foam aircraft need particular care when adhesives are involved. A repair adhesive should be compatible with the airframe material and appropriate for the structural load involved.

A small cosmetic foam repair is not the same task as repairing a highly loaded wing joint or landing-gear mount.

Three Good Examples of the FMS Parts Ecosystem

1700mm PA-18 Super Cub

The 1700mm PA-18 parts catalogue shows how a popular utility aircraft can be supported at several levels.

FMS lists components including the main wing, fuselage, motor mounting parts, wheel set, front landing gear, linkage rods, cowl, lamp covers, screw sets, servos, batteries and charging equipment.

This means repairs can range from replacing a tiny visual component to rebuilding a substantial part of the aircraft.

Browse FMS 1700mm PA-18 Super Cub Parts

1400mm P-40B Warhawk

A scale warbird places different demands on the spare-parts ecosystem.

The P-40B parts catalogue includes its main wing, propeller, spinner, landing gear, electronic retracts, motor mount, battery tray, ESC and several scale components.

This is exactly the kind of aircraft where an otherwise minor landing accident can affect several linked assemblies.

Being able to identify whether the fault lies in the retract, gear leg, wheel or mounting structure can prevent replacing more of the aircraft than necessary.

64mm F/A-18 Hornet

The F/A-18 illustrates the same principle in a compact EDF jet.

FMS lists replacement structural parts, landing systems, cockpit and scale components alongside servos and the ducted-fan propulsion system.

For anyone searching for FMS EDF jet replacement parts or trying to repair crash damage on a small electric jet, these aircraft-specific pages are considerably more useful than treating an EDF aircraft as a generic collection of components.

Repair or Replace the Complete Aircraft?

Not every damaged RC airplane should automatically be rebuilt.

The decision depends on how much of the aircraft remains sound.

If one wing, fuselage section, propeller, landing-gear assembly or electronic component is damaged while everything else remains usable, replacing individual parts usually makes sense.

If an accident damages the fuselage, both wings, multiple servos, power system and landing gear at the same time, the total cost and work involved may begin to approach the value of another complete aircraft.

There is also a third option: keep a heavily damaged model as a donor.

An intact motor, ESC, servos, landing gear, wheels, cockpit and hardware can all become useful spares for another aircraft of the same version.

This can be particularly valuable when a model eventually becomes discontinued and individual components become harder to find.

Do FMS Parts Fit Different Airplanes?

Sometimes, but compatibility should never be assumed.

FMS does use common components across selected aircraft. Propellers, servos, motors, batteries, chargers, connectors and other electronics may appear in more than one model.

Other parts are highly specific.

A fuselage, main wing, cowl, landing-gear assembly or cockpit is normally designed for a particular airframe.

Even when two aircraft use apparently similar electronics, wire length, direction, mounting geometry or software configuration can differ.

The safest method is to check the exact compatibility stated by FMS or locate the part through the model-specific Part Finder.

What FMS Airplane Parts Should Be Kept as Spares?

The most useful spares depend on the aircraft and flying style, but some components are more likely to be needed than others.

Propellers: inexpensive, easy to damage and worth keeping ready.
Spinners: vulnerable during nose-overs and propeller strikes.
Landing-gear parts: especially useful for trainers and aircraft flown from rough surfaces.
Wheels: simple to store and useful after hard landings.
Control horns and linkages: small components that can ground an otherwise healthy aircraft.
Servos: useful when the exact aircraft relies on a particular size or direction.
Screw sets and hardware: easy to lose during repairs and maintenance.
Battery packs: additional packs increase flying time and batteries naturally have a finite service life.

Large components such as fuselages and wings generally make more sense to buy when required unless a particular aircraft is discontinued or parts availability is becoming limited.

FMS Parts for Discontinued RC Airplanes

A discontinued aircraft is not necessarily unsupported immediately.

FMS still maintains model-specific parts pages for some aircraft that are no longer in current production.

This can make official spare stock particularly valuable to owners who intend to keep an older warbird, trainer or jet operating for several more seasons.

Availability will inevitably change over time, however, and a listing does not guarantee that every component remains permanently in stock.

For an older aircraft, it can therefore make sense to identify model-specific components that are difficult to substitute and buy them while official stock remains available.

FMS Airplane Parts for Beginners

Parts support is especially relevant when choosing a first RC airplane.

A beginner should not only ask which aircraft is easiest to fly. It is also worth asking what happens after the first bad landing.

An aircraft with readily available wings, fuselage parts, landing gear, propellers and electronics can be repaired and returned to the field rather than becoming an expensive lesson.

The broader FMS RC Airplanes Complete Buyer's Guide explains how trainers, warbirds, EDF jets and other FMS aircraft fit together by experience level.

For another overview of specific aircraft choices, the Best FMS RC Airplanes Guide covers beginner, intermediate and advanced options.

Buying a New FMS Airplane with Parts Support in Mind

Parts availability should be considered before the first flight, not only after something breaks.

Two aircraft may look equally attractive in the box, but the model with easily available structural and electronic spares can be substantially easier to own over several years.

This is particularly relevant for larger warbirds, EDF jets and models intended for frequent flying.

The purchase is not only the aircraft. It is also the ecosystem around it: batteries, propellers, landing gear, electronics, structural replacements and technical support.

The broader FMS RC Airplanes — The Complete Buyer's Guide compares the wider trainer, warbird, EDF, civil-aircraft and specialist ranges, making it useful when parts support is one of the criteria for choosing the next model.

FAQ — FMS RC Airplane Replacement Parts

Where can FMS RC airplane replacement parts be found?

FMS maintains an official airplane-parts catalogue and a model-based Part Finder. Searching by the exact aircraft is normally the safest way to locate compatible components.

Can a damaged FMS foam fuselage be replaced?

Yes. FMS lists replacement fuselages for many current and older aircraft, including trainers, warbirds and EDF jets. Some designs use separate front and rear fuselage sections.

Can an FMS RC airplane wing be bought separately?

Many FMS aircraft have replacement main wing sets available. Compatibility should be checked against the exact aircraft, wingspan and version.

Does FMS sell landing gear and retracts?

Yes. The parts catalogue includes fixed landing-gear components, wheels, electronic retract systems and aircraft-specific landing assemblies.

Does FMS sell replacement EDF units?

FMS lists EDF systems and related components for selected electric jets. Fan diameter, motor specification, battery system and aircraft compatibility should all be confirmed before replacement.

Are FMS propellers universal?

No. Some propellers are shared across several aircraft, but diameter, pitch and blade configuration vary. The correct replacement should be matched to the aircraft and power system.

Can parts from one FMS airplane fit another?

Some common electronic and mechanical components are used across multiple models, but compatibility should be verified rather than assumed. Structural parts are generally aircraft-specific.

Does FMS still sell parts for discontinued airplanes?

Some discontinued aircraft continue to have official parts listings while stock remains available. Long-term availability is not guaranteed.

Final Thoughts

The depth of the FMS airplane-parts catalogue changes the way an RC aircraft can be owned.

A broken propeller can be replaced. Bent landing gear does not necessarily mean a new airplane. A damaged wing or fuselage can often be treated as one component of the aircraft rather than the aircraft itself.

More complex models extend that logic further, with replacement retracts, servos, motors, ESCs, EDF systems, cockpits and scale details allowing repairs to remain targeted rather than becoming complete rebuilds.

The most important habit is simple: identify the exact FMS aircraft, confirm its version and use the model-specific parts catalogue before ordering.

That makes FMS airplane replacement parts useful not only after a crash, but as part of a longer ownership strategy — keeping trainers, scale warbirds and EDF jets flying instead of replacing them whenever one component fails.
