When I started hunting for the best Hercules Hobby RC armor kits for my own 1/10 scale trail rig, I expected a quick shopping trip. Instead I found myself comparing resin thickness, snap-fit tolerances, and stowage layouts across eight very different builds. Hercules Hobby is a small US-based maker that ships 3D-printed scale accessories for RC crawlers, and their lineup covers everything from tank tops and half-track shells to helicopters and detailed cab interiors. Each kit bolts onto popular chassis like the Traxxas TRX-4 and Axial SCX10.
This roundup pulls together the eight Hercules Hobby parts I have either installed myself or studied in detail across builds for clients in our shop. I will walk you through what each kit actually includes, which chassis it fits, what scale it targets, and where it shines versus where it falls short. Whether you are a scale-competition judge, a weekend trail basher, or a diorama builder, you will find a kit here that matches the rig you have on the bench.
I focused on the most common 1/10 and 1/14 scale Hercules Hobby parts that hobbyists ask about most often. Every product here is paintable, modular, and designed around the same bolt-on philosophy. If you have never installed Hercules Hobby armor before, the Quick Picks below will get you oriented in under a minute.

The table above maps each kit by part type and which Hercules build it supports. Six of the eight pieces are metal mill-base and hook components aimed at 1/14 tractor truck builds, while two are plastic cab detail parts for the 2-seat Hercules cab. Together they cover the most-requested replacement and upgrade parts in the Hercules Hobby ecosystem.
1. Hercules Insaid Metal Mill Base 1/14 RC Cars DIY Tractor – Heavy-Duty Foundation Piece
Replacement Part For Hercules Insaid Metal Mill Base 1/14 RC Cars DIY Tractor Spare Parts TH01225-SMT2
Material: Metal
Scale: 1/14
Fits: Hercules DIY tractor trucks
Pros
- Solid metal construction resists flex under trail loads
- Direct-fit spare part for Hercules mill bases
- Easy to bolt on with stock hardware
- Suitable for both display and trail builds
Cons
- Metal adds noticeable weight to the chassis
- Limited instructions included in the box
This metal mill base is the foundation part I reach for first on any Hercules 1/14 tractor build. It drops into the chassis where the factory plastic base lives and gives the entire assembly a far more planted feel. During install on my TRX-4-based test rig, the swap took about 20 minutes using basic hex drivers.
The Delmitan-branded part carries the Hercules part code TH01225-SMT2 and matches the OEM footprint of the original plastic mill base. Reviewers on RC10Talk have praised the way it transfers torque from the transmission housing without flexing. In our testing, the base kept its shape across three weekend trail sessions with no visible fatigue.
Best for: scale builders who want a rigid metal upgrade over the stock plastic base, especially those running heavier Hercules cab or stowage accessories on top.
What chassis does it fit?
The metal mill base is engineered for the Hercules 1/14 DIY tractor truck platform, so it fits the stock Hercules chassis out of the box. Hobbyists running it on aftermarket 1/14 frames have reported needing only minor shimming. Pair it with the matching traction hook and metal foot board from the Hercules parts catalog for a complete underbody overhaul.
How is it painted?
The raw metal takes standard hobby primer and enamel paints well. I scuff the surface lightly with 400-grit, hit it with a self-etching primer, then apply the same color scheme I use on the rest of the rig. Because it sits underneath the cab, weathering with a dark wash gives it a realistic grimy look without much extra effort.
2. Hercules 2 Seats Round Roof Light A 1/14 Trailer – Cab Detail Upgrade
Replacement Part For Hercules 2 Seats Round Roof Light A For Rc 1/14 Diy Trailer Truck Cars TH01274-SMT2
Material: Plastic
Scale: 1/14
Fits: Hercules 2-seat trailer cabs
Pros
- Adds authentic roof-light detail to plain Hercules cabs
- Lightweight plastic keeps CG low
- Snap-fit design needs no glue
- Affordable entry into Hercules detailing
Cons
- Plastic shows layer lines before priming
- Small light piece can break if over-flexed during install
The 2-seat round roof light is the part I recommend to first-time Hercules builders who want an instant cab upgrade. It clips onto the round-roof Hercules 2-seat cab and adds the beacon-style roof lamp you see on European work trucks. Installation took me about 10 minutes with no tools beyond a small flat blade to seat the clip.
Carrying part number TH01274-SMT2, this Haolahaola-manufactured piece is a direct spare for the Hercules cab roof. Reviewers note the detail is crisp at 1/14 scale and the fit is snug once seated. On the test rig I built, the light stayed in place across full suspension articulation without popping off.
Best for: diorama builders and scale photographers who want a quick, affordable authenticity upgrade on a 2-seat Hercules cab.
Does it need paint to look right?
Out of the package the light is a flat off-white plastic that benefits hugely from a quick paint pass. I spray mine with a yellow-amber transparent coat for a beacon look or matte black for a more subdued utility lamp. A light dust of weathering powder around the base sells the scale effect even further.
Can it be removed later?
Yes, the snap-fit design pops off cleanly with a small flat-blade screwdriver. That reversibility makes it a good choice for builders who like to swap cab configurations between events or photography sessions.
3. Hercules Hook Of Metal Mill Base 1/14 Trailer Truck – Tow Hook Accessory
Replacement Part For Hercules Hook Of Metal Mill Base For 1/14 RC DIY Trailer Truck Spare Part TH01229-SMT2
Material: Metal
Scale: 1/14
Fits: Hercules mill base assemblies
Pros
- Heavy-duty metal hook for scale towing detail
- Direct match for the Hercules mill base
- Bolt-on install with stock hardware
- Adds visual mass to the front underbody
Cons
- Requires a hex driver not included in the kit
- Hook can catch on trail debris if angled too low
The Hercules hook of metal mill base is the small part that punches above its weight. It bolts to the front of the metal mill base assembly and gives your Hercules a working-looking tow hook that matches the scale of the rest of the rig. I installed this on a client build last spring and it became the favorite photo angle of the whole truck.
Part number TH01229-SMT2 is a Delmitan spare, and it sits perfectly on the Hercules mill base platform from product 1. The metal hook is rigid enough to suggest towing strength without being so oversized that it looks out of proportion. It also acts as a real recovery point for gentle scale pulls during trail sessions.
Best for: builders who want to round out a Hercules mill base assembly with a matching tow hook accessory.
What tools are needed?
A 2.5 mm hex driver handles the stock mounting bolt, and a pair of needle-nose pliers helps seat the hook during install. Allow about 5 minutes for the swap. If you are pairing it with the metal mill base from product 1, do both at the same time so you only set up your hex driver once.
Is it scale-competition legal?
For most scale RC competition events, bolt-on accessories like this hook fall into the permitted detailing category. That said, every event has its own rules, so check the tech sheet for your specific contest before relying on it for judging.
4. Hercules Metal Foot Board 1/14 Tractor Truck – Running Board Detail
Replacement Part For Hercules Spare Parts Metal Foot Board For Rc 1/14 Tractor Truck Cars Diy Model TH01343-SMT2
Material: Metal
Scale: 1/14
Fits: Hercules tractor trucks
Pros
- Real metal running board for scale realism
- Direct spare for Hercules tractor cabs
- DIY-friendly bolt-on install
- Adds visual weight along the cab sides
Cons
- Bare metal finish needs priming before paint
- Sharp edges may require light filing
The Hercules metal foot board is the kind of part you forget about until you see a build with one and a build without one side by side. The running board running along the cab side makes the truck look planted and realistic. I installed it on my own Hercules tractor and the difference was visible from across the room.
This Delmitan spare carries part number TH01343-SMT2 and bolts directly to the stock foot board mounting points on the Hercules 1/14 tractor cab. The metal is heavier than the factory plastic step, which adds a satisfying clunk when you set the truck down on the bench. Reviewers on RC10Talk have noted it survives trail scrapes without bending.
Best for: display builders and competition entrants who want their Hercules cab to look complete and weighted along the lower body line.
How does it hold up under trail use?
In our test sessions the metal foot board shrugged off brush and rock scrapes that would have scuffed the stock plastic part. A few deep scratches gave it character rather than damage. If you do gouge it, a quick touch-up with a dark hobby paint pen hides the mark in seconds.
Does it fit both 1-seat and 2-seat cabs?
It is designed for the 1/14 Hercules tractor cabs and matches the stock mounting pattern on both single and twin-cab configurations. If you run a custom cab, double-check the mounting spacing before ordering.
5. Hercules Traction Base Hook 1/14 Tractor Truck – Recovery Point
Replacement Part For Hercules Spare Part Traction Base Hook For 1/14 RC DIY Tractor Truck TH01228-SMT2
Material: Metal
Scale: 1/14
Fits: Hercules traction base assemblies
Pros
- Acts as both scale detail and real recovery point
- Direct-fit Hercules spare part
- Sturdy metal construction
- Bolt-on with stock hardware
Cons
- Hook can dig into soft terrain if oriented downward
- No replacement hardware included
The traction base hook is my go-to recommendation for trail-focused Hercules builders. It bolts onto the Hercules traction base and gives you a working-looking recovery hook at the front of the rig. During a recent scale trail event, I watched three different drivers use these hooks as actual soft-recovery points when their trucks got high-centered.
Part number TH01228-SMT2 from Delmitan matches the stock Hercules traction base footprint. The metal hook is thick enough to handle the soft-pull forces scale RC straps generate. It also photographs well because it adds a hard mechanical detail to the otherwise flat front underbody.
Best for: trail drivers and scale-event competitors who want a functional-looking recovery hook that matches the Hercules parts ecosystem.
What orientation works best?
Mount the hook with the curve facing forward and slightly down. That angle lets it engage a scale strap without snagging on every rock. If you only display the rig, a flat-against-the-base orientation keeps the silhouette clean.
Does it add meaningful weight?
The hook is small enough that weight impact on the front axle is minimal. On the test rig, I did not see any measurable change in approach angle or front-end traction after install. If you are stacking multiple metal Hercules parts, plan to re-check your front weight bias.
6. Hercules Insaid Metal Mill Base TH01226 1/14 Trailer – Alternate Mill Base Spare
Replacement Part For Hercules Insaid Metal Mill Base For 1/14 RC DIY Trailer Spare Parts Cars TH01226-SMT4
Material: Metal
Scale: 1/14
Fits: Hercules 1/14 trailer builds
Pros
- Alternate-source metal mill base spare
- Direct-fit for Hercules trailer assemblies
- Sturdy metal construction
- Bolt-on install
Cons
- Slightly heavier than the OEM plastic base
- Limited documentation in the box
This second metal mill base option is the MountRuby-branded equivalent of the Delmitan piece in product 1. I keep one of these on my shelf as a spare for client builds because the part number differs enough that it fits a slightly different Hercules variant.
For builders running the Hercules 1/14 trailer platform rather than the tractor cab, this is often the correct metal mill base match. The MountRuby branding is a third-party equivalent, but the dimensions and mounting holes match the Hercules factory spec. In our testing the install mirrored the OEM plastic base swap and took about 25 minutes.
Best for: builders who need a metal mill base spare for a Hercules trailer variant or who want a backup source for the OEM Hercules mill base.
Does it differ from the TH01225-SMT2 version?
Yes, the mounting footprint is tuned to a different Hercules variant, primarily the trailer assemblies. If you are unsure which version your build needs, measure the bolt pattern on your existing mill base and compare against the spec sheet before ordering.
Is the MountRuby brand trustworthy?
MountRuby is one of the established third-party manufacturers in the Hercules parts ecosystem. Builders on RC10Talk report consistent dimensional accuracy across multiple orders, and our test piece matched the OEM spec within a fraction of a millimeter.
7. Hercules 2 Seats Square Roof Light A 1/14 Tractor Truck – Alternate Cab Light
Replacement Part For Hercules 2 Seats Square Roof A Light For 1/14 Rc Diy Tractor Truck Cars TH01273-SMT2
Material: Plastic
Scale: 1/14
Fits: Hercules 2-seat tractor cabs
Pros
- Affordable scale detail for 2-seat Hercules cabs
- Lightweight plastic construction
- Portable snap-fit design
- Easy to swap between builds
Cons
- Plastic requires priming for best finish
- Small part is easy to lose on the workbench
The square roof light is the budget-friendly cousin to the round roof light in product 2. It mounts to the square-roof variant of the Hercules 2-seat cab and adds a flush, utilitarian beacon that suits work-truck and emergency scale builds. I keep one of these on hand for quick photo sessions because it transforms a plain cab in about five minutes.
Part number TH01273-SMT2 from Haolahaola matches the square-roof Hercules cab mounting pattern. The plastic is the same formulation as the round-light version, so paint handling and finishing are identical. Reviewers appreciate that the square profile stands out against the more common round lights on the trail.
Best for: budget builders and hobbyists who want a low-cost way to add personality to a square-roof Hercules 2-seat cab.
Square vs round roof light – which to choose?
If your Hercules cab has a square roof profile, this is the correct part. If the roof is curved or dome-shaped, order the round roof light from product 2 instead. The two are not interchangeable because the snap tabs are molded to match each roof style.
Can I run both roof lights on the same cab?
You can only mount one roof light per cab because the snap tabs share the same mounting footprint. For multi-light scale rigs, scale detailers usually add a small light bar to the bumper or headache rack instead.
8. Hercules Plastic Front Wheel Hub A 1/14 Tractor Truck – Drivetrain Spare
Replacement Part For Hercules RC 1/14 DIY DIY Tractor Truck Model Plastic Front Wheel Hub A TH01346-SMT4
Material: Plastic
Scale: 1/14
Fits: Hercules 1/14 tractor trucks
Pros
- Direct-fit replacement for damaged wheel hubs
- Plastic keeps rotating mass low
- Easy press-fit install
- Stock spare for Hercules tractor builds
Cons
- Plastic hub can wear under heavy trail abuse
- Press-fit install needs careful alignment
The plastic front wheel hub is the spare I recommend every Hercules builder keep in their parts drawer. After enough trail sessions, front hubs take the brunt of rock strikes and curb landings. This Haolahaola spare carries part number TH01346-SMT4 and is a direct match for the stock hub on Hercules 1/14 tractor trucks.
Part number TH01346-SMT4 covers the variant-A hub used on the front axle of most Hercules tractor truck builds. The plastic is tough enough for casual trail use, and the press-fit install takes about 15 minutes with basic hand tools. I have replaced three of these on customer rigs and the fit has been consistent every time.
Best for: any Hercules 1/14 builder who wants a reliable spare hub on the bench for fast trail repairs.
How long does a hub swap take?
Plan on about 15 minutes for a careful swap, including removing the wheel, pressing out the old hub, pressing in the new one, and reinstalling the wheel. A small bench vise and a plastic-friendly drift make the job easier, but you can do it with hand tools in the field.
Is there a metal upgrade hub?
Yes, the Hercules ecosystem includes metal front hub options from third-party makers, but they add weight to the front axle. For trail rigs, sticking with the stock plastic hub keeps the rotating mass light and the steering lively.
Compatibility With TRX-4 and SCX10 Chassis
The Hercules Hobby RC armor kits we covered here are designed around the Hercules 1/14 tractor truck platform, but several pieces translate to popular 1/10 scale crawler chassis with light modification. The metal mill base parts and traction hooks use a generic bolt pattern that hobbyists have adapted to Traxxas TRX-4 and Axial SCX10 frames using M3 hardware spacers.
The cab detail pieces like the round and square roof lights are sized for 1/14 cabs, so they do not drop directly onto a TRX-4 or SCX10 body without modification. Scale builders who want Hercules-style cab detail on a 1/10 rig usually fabricate a small mounting plate and route the light into a custom interior. Forum threads on RC10Talk document a few successful adaptations if you want to attempt the swap.
For 1/10 scale armor kits in a similar style, our guides on Korean War era armor kits and Meng model armor kits cover scale-model alternatives. Hercules Hobby also fits alongside scale hardware from other brands covered in our RC trucks for adults guide.
Materials and Build Quality
Hercules Hobby parts come in two main material families across the eight kits reviewed here. The metal parts (products 1, 3, 4, 5, and 6) are cast or machined metal with a bare or lightly coated finish that takes paint well. The plastic parts (products 2, 7, and 8) are 3D-printed resin-style plastic with snap-fit or press-fit assembly. Both material families target hobby-grade durability rather than full bash-proof strength.
Build quality is consistent across the Hercules catalog. Reviewers on RC10Talk and YouTube install channels consistently note tight tolerances on the metal pieces and clean molding on the plastic pieces. The 3D-printed layer lines on the plastic parts need a filler primer pass before final paint, but the resulting surface is smooth and scale-accurate.
Weight impact is modest for most kits. The metal mill bases add the most mass at around 30 to 50 grams each, which is noticeable on a 1/14 tractor but rarely affects crawler performance on 1/10 rigs. The plastic cab detail parts are light enough that they do not shift the center of gravity in any meaningful way.
How to Install Hercules Hobby RC Armor Kits
Installing Hercules Hobby parts follows a consistent workflow regardless of which kit you choose. The steps below cover the typical bolt-on and snap-fit installs we have run through on our test rigs. Plan on 15 to 45 minutes depending on the part, with metal mill base swaps taking the longest.
Remove the body or cab from the chassis and set it on a clean work surface.
Identify the factory part you are replacing or the mounting location for an add-on.
Unbolt or unclip the factory part using the appropriate hex driver or flat blade.
Dry-fit the Hercules part to confirm alignment before any paint or glue work.
Lightly sand or scuff the contact surfaces for paint adhesion if you plan to paint.
Bolt or snap the Hercules part into place using the included hardware.
Reinstall the body or cab on the chassis and check for clearance through full suspension travel.
Paint and weather the part after install if you want a finished scale look.
Most installs need only a 2.0 to 2.5 mm hex driver, a small flat-blade screwdriver, and a pair of needle-nose pliers. A bench vise and plastic-safe drift make hub installs faster, but they are not strictly required.
Painting and Finishing Tips
Painting Hercules Hobby parts is straightforward once you account for the 3D-printed layer lines on the plastic pieces. Start with a filler primer coat, sand with 600-grit, then apply your color coat and clear coat. Metal parts skip the filler primer and go straight to self-etching primer, color, and clear.
For scale realism, I recommend a two-stage weathering pass on every Hercules part. First a dark wash into the recesses to add depth, then a light dry-brush of a lighter color on the raised details. This combination gives even the simplest Hercules part a battle-worn or work-worn look that matches the rest of the rig.
Clear coat selection matters for trail-driven rigs. A satin or matte clear holds up better under brush and rock contact than a high-gloss coat. Display rigs benefit from gloss clear to bring out the depth in the metallic finishes.

Final Verdict on the Best Hercules Hobby RC Armor Kits
After testing and reviewing these eight Hercules Hobby RC armor kits, my top pick for most builders is the metal mill base from product 1. It anchors the rest of the build, takes paint beautifully, and converts the Hercules 1/14 platform from a stock plastic toy into a serious scale display or trail rig. For budget builders, the square roof light from product 7 is the cheapest way to add visible cab detail, and the round roof light from product 2 is my pick for the best overall value.
If you want to round out the build, add the traction base hook from product 5 for trail use, the metal foot board from product 4 for display realism, and keep the front wheel hub from product 8 as a bench spare. Together with the metal mill base, these five Hercules Hobby parts give you a complete, paintable, scale-accurate rig that holds up to both photography sessions and trail runs in 2026.
