FMS Viper 90mm Retract Landing Gear Set
I picked up the FMS 90mm Viper Retract Landing Gear Set because my original gear started sticking during landings, and this one kept popping up in RC forums as a reliable upgrade. The specs promised smoother deployment and better shock absorption — two things I desperately needed for my rough grass landings.
Out of the box, the parts felt solid. Aluminum construction, pre-wired retracts, and a surprisingly tight fit to my Viper 90mm model. Installation was pretty much plug-and-play — no grinding or guesswork. The servos responded quickly, and the retraction was smooth and precise. Even on rough terrain, the gear held up and didn’t bounce like cheaper setups I’ve tried before.
Pros:
-
Robust metal build
-
Fast, quiet retracts
-
Fit perfectly on the FMS Viper
-
Great value for the money
Cons: – Instructions were minimal – Slightly heavier than stock gear
At around $80 shipped, it’s much cheaper than anything I found locally in the U.S., where similar sets run closer to $120–$140. Honestly, this retract system exceeded my expectations. The performance feels premium, and it’s a major upgrade over stock gear.

FMS Viper RC Plane Spare Small Parts Kit
I ordered this FMS Viper Small Parts Kit (FMS90VP) mainly to stock up on essentials like servo horns, control rods, and linkages. These tiny parts tend to break mid-flight or go missing after a rough landing, and it’s smart to have backups ready.
The packaging was neat, each component individually bagged. What I really liked was that it included all the minor components that are normally a hassle to track down. The quality is consistent with the original parts that came with my Viper.
Pros:
-
Comprehensive set of spare small parts
-
High compatibility with FMS planes
-
Good fit and finish
Cons: – Would’ve liked a few spare screws included – No part labels, had to figure out what was what
I paid under $20, which is excellent considering that buying these parts individually in the U.S. would cost nearly double. Totally worth it for peace of mind and quick repairs.

FMS 90mm Avanti EDF Accessories Set (Wings, Fuselage, Tail)
My Avanti had a nasty crash that totaled the fuselage and broke one wing clean off. Rather than buying a whole new plane, I went for this FMS 90mm Avanti EDF Full Accessories Set to rebuild it.
What arrived was surprisingly high quality. The fuselage was smooth with all the mounting points in the right place. The main wings and vertical stabilizer aligned perfectly with zero warping. Paint job and decals matched my original Avanti almost identically.
Pros:
-
Factory-matching paint and fit
-
Much cheaper than a whole new Avanti
-
Pre-installed wiring made rebuild easy
Cons: – Long shipping time (3 weeks) – No manual or assembly guide included
I paid around $130, which is a steal compared to buying individual parts in the U.S. or going for a new kit entirely. Rebuilding the Avanti instead of scrapping it saved me a ton, and I’m genuinely surprised how well everything aligned.

FMSRC Avanti 90mm Thrust Vectoring Nozzle Unit
Thrust vectoring has always intrigued me, and this FMSRC 90mm Avanti Thrust Vectoring Unit was a great excuse to try something new on my jet. It promised tighter maneuvers and post-stall control — which sounded like a blast.
The aluminum build is beautiful — precision machined and light. It took some finagling to integrate it with the EDF and program my radio mixes, but once I got it dialed in, wow. Knife edges, spins, and cobra maneuvers became easy. It really brings a 3D touch to an EDF jet.
Pros:
-
High-grade aluminum
-
Excellent control authority boost
-
Adds serious fun factor
Cons: – Not beginner-friendly to install – Needs radio with custom mixing capability
For under $60, it’s half the cost of similar vector units I’ve seen stateside. It transformed my Avanti from a fast cruiser into a full-blown aerobatic machine.

FMS 90mm Viper Full Wing & Tail Replacement Kit
I wanted to refresh my aging FMS 90mm Viper without doing a full rebuild, and this FMS Viper Wing and Tail Kit was the perfect option. The wings on my original had hairline cracks and one of the control horns had pulled out. Rather than patch it up, I ordered this kit.
When the box arrived, the parts were well-protected. Foam was dense and paintwork sharp. Control surfaces moved freely, and everything was pre-hinged. Installing them took less than an hour.
Pros:
-
Direct swap fit
-
Looks factory-new
-
No additional hardware needed
Cons: – Some minor shipping dings – Would’ve liked optional decals included
Price was around $70, and compared to buying OEM parts in the U.S. (which can exceed $110), this was great value. The Viper flies like new again — definitely satisfied.

Freewing 90mm Metal EDF with Motor (12 Blade, 6S/8S Options)
This Freewing 90mm Metal EDF Unit (I got the 12-blade 6S version with 4068 1750KV motor) was my attempt to boost performance on an old airframe I had lying around. The build quality looked excellent online, and I wasn’t disappointed in person.
The unit came fully assembled with dynamic balancing. Hooking it up to my ESC was simple. The 12-blade setup sounds amazing — that real jet “whoosh” — and the thrust is no joke. Compared to my old stock EDF, this thing is an absolute powerhouse.
Pros:
-
Excellent thrust-to-weight ratio
-
Beautiful turbine-like sound
-
Runs cool and balanced
Cons: – Heavy for smaller airframes – Slight vibration at full throttle
I paid just over $100, and you’d easily pay $180–$200 for something like this in the U.S. It’s a high-performance upgrade at a fraction of the cost, and totally worth it for anyone looking to revive or upgrade a 90mm EDF bird.
US $102.39
Final Thoughts
I went into these AliExpress orders a bit skeptical — I’ve been burned before by cheap RC parts. But honestly, every single product here delivered solid performance, great value, and surprisingly good quality. Shipping ranged from 2 to 3.5 weeks, which is fair for international delivery.
Would I recommend these products? Absolutely — especially if you’re into EDF jets and want solid upgrades or spare parts without breaking the bank. I’m already browsing more FMS and Freewing parts for my next build. AliExpress has definitely earned a spot in my RC supply rotation.
