FMS RC Airplane Parts in 2026 — Wings, Fuselages, Landing Gear, Motors & EDF Spares
A damaged wing, fuselage, propeller or landing-gear component does not necessarily mean replacing an entire FMS RC airplane. FMS maintains a large model-specific parts ecosystem covering structural components, propulsion, electronics, landing systems and smaller repair hardware for current and selected discontinued aircraft.
Editorial Note: This guide explains the FMS replacement-parts ecosystem and repair logic. Part availability and compatibility change over time, so always match the component to the exact aircraft, wingspan, generation and SKU before ordering.
For choosing the aircraft itself, see our FMS RC Airplanes in 2026 Complete Guide. Beginners can also use our FMS Beginner RC Planes guide, where parts support is one of the buying criteria.
Start with the Exact Aircraft, Not the Part Name
The safest way to buy an FMS replacement part is to start with the exact aircraft.
Model families can exist in multiple wingspans and generations. A P-51, Ranger, PA-18 or EDF jet may have several versions that use different fuselage mouldings, landing systems, servos or electrical components.
FMS therefore provides a model-based Part Finder rather than relying only on generic component categories.
Compatibility rule: match the aircraft name, wingspan, version and stated compatibility. A component that looks identical is not automatically interchangeable.
FMS Airplane Parts at a Glance
| Part Type | Typical Reason for Replacement | Compatibility Risk |
|---|---|---|
| Propeller / Spinner | Nose-over or prop strike | Diameter, pitch, blade count and shaft fit |
| Landing Gear | Hard landing or rough field | Strut geometry, retract unit and mounting system |
| Wing | Tip strike, transport damage or crash | Exact airframe generation and wingspan |
| Fuselage | Structural crash damage | Generation, colour scheme and installed hardware |
| Servo / Linkage | Control failure or physical damage | Direction, wire length, mounting size and travel |
| Motor / ESC | Power-system repair | KV, voltage, current rating and connector system |
| EDF Unit | Jet propulsion repair | Fan diameter, motor and aircraft power system |
Replacement Fuselages
A badly damaged fuselage can appear terminal, but FMS sells replacement fuselage components for many models.
Some aircraft use one main fuselage assembly, while others divide the structure into several replaceable sections.
The economic question is what survived. If the wing, power system, servos and landing gear remain usable, replacing the fuselage can make considerably more sense than replacing the complete aircraft.

Replacement Wings
Wing damage can come from a tip strike, heavy landing, transportation accident or structural damage around a landing-gear mount.
FMS sells aircraft-specific wing assemblies across trainers, warbirds and EDF models.
Check the listing carefully because the contents of a wing set vary. Control surfaces, servos, connectors or hardware may or may not be included depending on the aircraft.
Wingspan is particularly important. Two models based on the same real aircraft can be completely unrelated RC platforms if one is 800mm and the other 1400mm.
Horizontal Stabilisers and Tail Components
Tail damage does not necessarily require a complete fuselage.
FMS also lists horizontal stabilisers, vertical stabilisers, braces and other tail-related components for many aircraft.
This can be useful after storage or transport accidents, where a tail surface is damaged despite the aircraft never being flown.
Landing Gear, Wheels and Retracts
Landing systems are among the most frequently exposed components on a flying model.
A fixed-gear trainer may require only a wheel, spring or landing-gear assembly. A warbird or EDF jet can use electronic retracts, dedicated struts and model-specific mounting hardware.
Before ordering, determine whether the failed component is actually the wheel, strut, retract mechanism, mounting point or complete gear assembly.
Propellers and Spinners
Propellers are inexpensive compared with most structural components and are sensible spares to keep available.
But they are not universal.
Diameter, pitch and blade count influence motor load and aircraft performance. The replacement should therefore match the aircraft and power system specified by FMS rather than simply fit the motor shaft.
The same applies to spinners, particularly after a nose-first impact.
Motors and Mounting Hardware
A propeller strike does not always damage the motor itself. The shaft, motor mount or motor board can fail while the motor remains usable.
That is why FMS's parts system separates several of these components.
When a motor genuinely needs replacing, KV rating, physical dimensions, shaft arrangement, battery voltage and propeller load all matter.
For a stock repair, the original FMS-specified motor is normally the most straightforward route.
ESCs and Electrical Compatibility
An ESC replacement needs more attention than matching connector shapes.
Current rating, supported battery voltage, BEC output and motor requirements all affect compatibility.
If the aircraft is otherwise stock, reproducing the original electrical specification avoids turning a simple repair into a full power-system redesign.
Servos, Control Horns and Linkages
Servo compatibility can depend on dimensions, rotation direction, wire length, travel and the control surface being operated.
Small components such as control horns, clevises and linkage rods also matter disproportionately because failure can make an otherwise complete aircraft unsafe to fly.
This is another area where the model-based Part Finder is preferable to buying something because it looks similar.
EDF Units and Jet-Specific Spares
EDF aircraft add another repair layer because the fan, motor and duct form an integrated propulsion system.
Fan diameter alone is not enough to establish compatibility. The motor, ESC, battery system, mounting geometry and complete aircraft installation must also match.
For example, an FMS 64mm jet should not be treated as interchangeable with a 70mm, 80mm or 90mm installation simply because all use electric ducted fans.
For the aircraft side of that progression, see our FMS EDF Jets in 2026 guide.
Reflex Controllers
Reflex V3 is another component where compatibility and configuration matter.
The current system supports a wide range of FMS aircraft and provides Stabilized, Optimized and Manual modes, but the correct installation and aircraft configuration should still be confirmed.
Do not assume a Reflex unit moved from one model to another is automatically ready to fly without the appropriate configuration.

Batteries and Chargers
Batteries are both operating equipment and consumable components.
Compatibility depends on cell count, voltage, connector, capacity, discharge capability, physical dimensions and weight.
A battery can be electrically suitable but still be a poor choice if it does not fit securely or moves the centre of gravity outside the intended range.
Floats and Aircraft-Specific Accessories
Several utility and trainer aircraft support optional floats.
These should be treated as model-specific systems because mounting geometry and aircraft balance matter.
PA-18, Ranger and other utility-style aircraft can support float configurations depending on the exact model and version.
Scale Details and Cosmetic Parts
Warbirds and scale jets may also have replaceable cowls, cockpit sections, pilot figures, antennae, exhaust parts, lights and other visual components.
These do not necessarily affect flight performance, but they allow an otherwise healthy aircraft to be restored without replacing a complete airframe simply because one visible part is damaged or missing.
Three Examples of Model-Specific Parts Support
1700mm PA-18 Super Cub V2
The current parts collection for the 1700mm PA-18 includes items such as propellers, motor components, spinner, float set, servos, ESC, landing-gear parts, main wing, horizontal stabiliser, linkage rods and smaller hardware.
This is a good illustration of how repairs can be targeted at the failed assembly rather than the complete aircraft.
1400mm P-40B Warhawk
The P-40B itself is currently marked discontinued by FMS, but the manufacturer still maintains a model-specific parts collection containing items such as spinner, propeller, motor components, retract parts, battery tray and other hardware while stock remains available.
This is why owners of discontinued aircraft should distinguish between the airframe being discontinued and all support disappearing immediately.
90mm Avanti
The current 90mm Avanti parts ecosystem includes categories for structural parts, servos, EDF system components, ESCs, landing systems and Reflex-related equipment.
That kind of support matters on a large performance jet because damage to one system should not automatically make the rest of the airframe disposable.
Repair or Replace the Complete Aircraft?
Repair normally makes sense when the damage is concentrated in one or two replaceable assemblies and the rest of the aircraft remains structurally and electronically sound.
If a major crash damages the fuselage, wings, several servos, power system and landing gear simultaneously, the total replacement cost and labour can begin to approach the value of another aircraft.
A badly damaged model can also become a useful donor aircraft. Motors, ESCs, servos, landing gear, wheels, cockpit parts and hardware may remain valuable if they match another aircraft of the same version.
Parts for Discontinued FMS Airplanes
FMS continues to list replacement components for some discontinued models while stock remains available.
That can make model-specific parts worth considering earlier if you intend to keep an older aircraft flying for many years.
However, a listing today does not guarantee indefinite future stock.
Which Spares Are Worth Keeping?
- Propellers — inexpensive and easily damaged.
- Spinners — vulnerable during nose-overs.
- Landing-gear hardware — useful after rough landings.
- Control horns and linkages — small parts that can ground an aircraft.
- Aircraft-specific screws and hardware — easy to lose during repairs.
- Battery packs — both for additional flying time and normal long-term replacement.
Large fuselages and wings generally make more sense to purchase when actually required, unless the aircraft is discontinued and future parts availability is uncertain.
Parts Support as a Buying Criterion
Parts availability is worth checking before buying the airplane, not only after an accident.
A model backed by replacement wings, fuselage parts, landing gear, propulsion and control hardware can be substantially easier to own over several seasons.
That is particularly relevant for a first aircraft, which is why parts availability is also included in our FMS Beginner RC Planes guide.
