Who each one is for

✅ FMS Avanti 90mm:

• Your first 90mm sport jet
• You mostly fly 6S, casual sport flying, touch-and-go, smooth aerobatics
• You value known reliability, spare parts availability, and a “set it up and enjoy” jet

✅ Freewing Avanti 90mm:

• You already have 90mm experience and want more performance
• You plan to run 8S, try vector / 3D EDF, or maybe turbine conversion later
• You travel to fly sites often and want fast wing assembly

Quick rule of thumb

If this is your first 90mm EDF sport jet: FMS Avanti is the safer, better-rounded choice. If you’re an experienced EDF pilot chasing maximum performance and flexibility: Freewing Avanti 90mm.

Are there any spare parts available for the Freewing Avanti 90mm jet?

Yes, official spare parts do exist for the Freewing Avanti 90mm, but the availability is not as widespread as the FMS Avanti 90mm right now (this is the main downside compared to FMS)Freewing.

What you can get

• Airframe parts: fuselage, main wing set, horizontal / vertical stabilizers, nose cone, canopy, gear doors, decals
• Power system: complete 90mm 12-blade EDF unit, fan blades, motor, reversing 120A ESC
• Mechanical: full retract units, struts, wheels, landing gear axles, control horns
• Electronics: matched 9g /17g metal gear servos, LED light boards, vector nozzle set

Where to buy

1. Freewing official website / factory email: [email protected] — this is the most reliable source for hard-to-find parts, they ship worldwideFreewing
2. Authorized Freewing dealers (US, EU, China hobby shops, Taobao)
3. Some RC jet specialty stores stock the common wear items (fan, retracts, canopy)

Important caveat

This is still a newer model, so many general hobby retailers do not keep all parts in stock on the shelf. You often need to special-order directly from Freewing or their distributor, and lead times can be longer. By contrast, FMS 90 Avanti parts are stocked by many shops and ready to ship most of the time.

Quick tip

If you plan to crash often and want instant access to spares: FMS is safer. If you are careful and okay with ordering parts direct when needed: Freewing spares support is sufficient.

Are there any third-party spare parts available for the Freewing Avanti 90mm jet?

No dedicated, pre-made third-party airframe parts (fuselage, wings, stabs, canopy) are made specifically for the Freewing Avanti 90mm. There is no aftermarket mould for this exact airframe yet, unlike the FMS Avanti 90 which has a bigger user base and some community printed parts.

But you can use generic third-party RC parts as replacements/upgrades:

✅ Generic third-party parts that work

1. 90mm EDF systems: JP, HSD, XFLY, Freewing generic 90mm 12-blade fans, aftermarket 3668 inrunner motors, 120A/150A reversing ESCs. It fits standard 90mm EDF housing; you just check mount spacing and battery voltage (6S /8S)
2. Servos: Generic 9g /17g metal gear digital servos (reverse servos where needed). You will need to match arm length and plug
3. Retract upgrades: CNC aluminum shock struts, bigger wheels, brakes, alternate retract controllers. The stock retract mounting geometry is standard enough for many 90mm jet retract mods
4. 3D printed community parts (on Thingiverse, Printables, RC groups): Custom gear doors, servo mounts, battery trays, air brake mounts, reinforcement plates. These are user-made, not commercial, so fit varies and you need to print yourself
5. Gyro / flight controller: Reflex, Jeti, EagleA, ArduPilot, etc. — fully compatible as a replacement or upgrade gyro

❌ What you cannot easily get third-party

• Pre-printed or carbon replacement fuselage, main wing, horizontal/vertical tail, canopy, nose cone molded for this Freewing Avanti 90
• Plug-and-play aftermarket vector nozzle made for this model (only Freewing official vector set is direct fit)

Important comparison vs FMS Avanti 90

FMS Avanti 90 has a much larger aftermarket scene: ready 3D prints, some carbon reinforced parts, custom vector kits sold by small vendors. Freewing’s version is newer and less popular, so the third-party ecosystem is thin.

Quick summary

If you break foam airframe parts: you’re almost stuck with Freewing official spares. If you break electronics/fan/retracts: lots of generic third-party alternatives will work with a little adaptation.

Do you want me to list a reliable generic 90mm EDF drop-in upgrade option for this jet?

Drop-in / near-drop-in 90mm 12-blade EDF options for Freewing Avanti 90mm

Stock setup: 6S = 3668-1960KV; 8S = 4075-1350KV, 12-blade, 120A reversing ESCFreewing M.... The Avanti’s shroud opening is standard 90mm round; most 90mm 12-blade units fit the duct, but motor mount spacing and reversing ESC are the gotchas.

Important note: Nothing is 100% plug-and-play like the Freewing OEM fan. All third-party fans will need at minimum connector swap, and some need minor mount shimming / adapter. Reversing thrust only works if you keep a reversing ESC.

1. JP 90mm 12-blade EDF (Most popular third-party sport jet choice)

• 6S version: 3668 1900KV, ~4.6–4.8kg thrust
• 8S version: 4074 1300KV, ~5.4–5.6kg thrust
• Housing: CNC metal shroud, balanced 12-blade composite impeller
• Fit: Best near-drop-in, same overall length as Freewing 90mm Mark II fan; most Freewing 90 jets take JP with only a simple 3D printed adapter plate if needed
• Pros: Super smooth, low noise, excellent efficiency, huge RC jet community support, balanced impellers out of box
• Cons: Pricier; you must reuse or buy a reversing ESC if you want thrust reverse for landing

2. XFLY 90mm 12-blade metal EDF (Budget performance pick)

• 6S: 3668 1960KV (almost identical KV to stock Freewing 6S motor)
• 8S: 4075 1350KV (matches stock 8S KV perfectly)
• Pros: KV matched exactly to OEM, direct thrust profile, cheaper than JP, balanced
• Cons: Build quality is a step below JP; some units need minor shaft runout check; shroud flange holes do not line up perfectly, small adapter required

3. Freewing Mark II Pro 90mm 12-blade (Official upgrade, not third-party)

• 6S: ~4.7–4.9kg, 8S: ~5.5–5.7kg thrustFreewing M...
• This is Freewing’s upgraded metal framed fan, direct bolt-in replacement.
• I list it here as a benchmark: zero fitting work, retains all stock wiring/reverse function. Best reliability, but it’s OEM, not third-party.

ESC rule (critical for this Avanti)

The stock system uses thrust reversing ESC.

• If you keep reverse: Buy a 120A–130A reversing EDF ESC (JP, ZTW, Hobbywing).
• If you don’t care about reverse: Cheaper standard 120A non-reversing ESC works, but you lose the Avanti’s nice reverse landing feature.

My recommendation for you

• If you want the smoothest, most reliable third-party upgrade: JP 90mm 12-blade
• If you just want a cheap direct KV match replacement motor/fan: XFLY 90mm 12-blade
• If you want zero hassle and keep reverse working perfectly: Grab the Freewing Mark II Pro OEM fan

Quick install checklist before ordering

1. Confirm you are staying 6S or 8S, pick the matching KV
2. Get EC5 connectors to match the plane’s stock harness
3. Print a simple 4-hole motor adapter plate (Printables has generic 90mm E adapters)
4. Re-balance the impeller if you swap just blades, not the whole fan unit
