What Makes an RC Car ‘Hobby Grade’ vs ‘Toy Grade’? (And Why MJX & FMS Are Miles Ahead)
Share
If you’re new to RC cars, you’ve probably noticed something confusing:
Two RC vehicles can look similar…
They can cost roughly the same…
They can both claim “high speed,” “off-road,” and “2.4GHz” on the box…
Yet one lasts 10 minutes and breaks, while the other lasts for years, takes real crashes, can be repaired, upgraded, and driven like a proper machine.
Welcome to the difference between toy grade and hobby grade.
At The Truck Monster, we only stock true hobby-grade RC cars — mainly from MJX and FMS — because we’ve tested everything else and know exactly what’s worth your money, and what isn’t.
Here’s what really separates the two worlds.
1. Build Quality & Materials
Toy Grade
Toy RC cars are made from thin, brittle plastics.
They’re glued together, one-piece units, and not designed to be opened or repaired.
-
Hollow plastic gears
-
Weak plastic steering components
-
No bearings (just plastic-on-metal friction)
-
Snap-fit parts with no replacement
Once something breaks? That’s it — the car is done.
Hobby Grade (MJX & FMS)
Hobby-grade cars use engineered materials designed to handle real forces:
-
Reinforced nylon or composite chassis
-
Steel or metal gears
-
Full ball bearings throughout
-
Proper screws and modular components
-
Aluminium oil-filled shocks
-
Heat sinks, metal driveshafts, CNC parts (model dependent)
This isn’t built like a toy — it’s built like a miniature vehicle.
2. Power & Electronics
Toy Grade
Toy RC cars use extremely basic electrics:
-
Weak brushed motors
-
Sealed, non-serviceable gearboxes
-
Cheap circuit-board “all-in-one” electronics
-
No upgrade path
-
5–10 minute run times
-
Limited range
-
No LiPo compatibility
Everything is designed around cost, not performance.
Hobby Grade (MJX & FMS)
This is where the difference truly explodes.
MJX and many FMS models use:
-
High-power brushless motors
-
60A programmable ESCs
-
Digital steering servos
-
Modular, upgradeable electronics
-
LiPo power
-
Genuine 100–200m radio range
-
Proportional throttle and steering
Some MJX trucks hit 55–65 km/h out of the box.
A toy-grade car claiming “40 mph” would struggle to hit 15mph.
3. Repairability & Spare Parts
Toy Grade
There are no spare parts.
No diagrams.
No screws to undo.
No upgrades.
When it breaks — and it will — it becomes landfill.
Hobby Grade (MJX & FMS)
Every part is replaceable:
-
Arms
-
Shocks
-
Servo
-
Motor
-
Diff
-
Driveshafts
-
Pinions
-
Spur gears
-
Tyres
-
Shells
You can strip and rebuild an MJX truck like a real machine.
Parts are affordable, widely available, and designed for maintenance.
4. Performance
Toy Grade
Performance is limited by design:
-
Weak acceleration
-
Poor suspension
-
No damping
-
Low grip tyres
-
Jerky throttle
-
Steering delay
-
Can’t handle grass or rough terrain well
Toy grade looks like a car — but doesn’t drive like one.
Hobby Grade (MJX & FMS)
Real suspension, real power, real control.
MJX offers:
-
Oil-filled aluminium shocks
-
Off-road tyres
-
Metal drivetrains
-
Sharp, proportional steering
-
High top speeds
-
True off-road capability
-
Stability at speed
FMS models excel in:
-
Realistic scale detail
-
Soft crawler tyres
-
Excellent articulation
-
Smooth low-speed control
-
Quality waterproof electronics
-
Realistic bodywork and interiors
5. Upgrades & Modding
Toy Grade
There are no upgrade options.
You can’t open them. You can’t tune them.
Hobby Grade (MJX & FMS)
The upgrade paths are endless:
-
Brushless systems
-
Better servos
-
Higher C-rated LiPos
-
Pinions and gears
-
Steel diffs
-
Improved shocks
-
Body shells
-
Tyres
-
LEDs
-
Aluminium components
You can tune an MJX or FMS car to your exact preference.
6. Price Comparison: The Part Most People Miss
This shocks most beginners.
A lot of toy-grade RC cars now sell for £80–£120 in big retail stores, with no spare parts or upgradeability.
For the same money — or less — you can get:
-
Brushless power
-
Metal gears
-
LiPo performance
-
Oil-filled shocks
-
Spare parts availability
-
Real durability
-
Real range
-
True hobby-grade engineering
You simply get vastly more for your money with MJX and FMS.

Final Thoughts: Don’t Be Fooled by Similar Prices
Toy-grade RC cars are built to be disposable.
Hobby-grade RC cars are built to be driven, repaired, upgraded, and enjoyed for years.
For similar money, you get:
-
Better materials
-
Better electronics
-
Better performance
-
Better parts support
-
Better long-term value
