HobbyPlus DKR-4 Fortis 12% Off at FairRC — Brushed vs Brushless Sale Guide
FairRC has reduced all four HobbyPlus DKR-4 Fortis combinations in its current promotion, covering both red and white bodies and the choice between brushed and brushless power. The important decision is not really colour — it is whether the lower-cost brushed version already gives you what you want from this unusual 1/18 desert-rally platform, or whether the 3500KV brushless system is worth stepping up to from the start.
The HobbyPlus DKR-4 Fortis is not a conventional micro crawler. Its portal axles, long-travel suspension, front and rear anti-roll bars and remote-operated two-speed transmission are wrapped inside a hard-body desert-rally truck designed to mix trail driving with faster loose-surface running.
We have already covered the chassis, drivetrain, rally design and detailed specification in our full HobbyPlus DKR-4 Fortis 1:18 Rally Truck Guide.
This page therefore focuses on the current FairRC promotion and the decision that matters most before buying: brushed or brushless?
Sale note: the prices below are those advertised by FairRC in its 16 October 2026 DKR-4 Fortis campaign. Promotional pricing and availability can change, so confirm the current product page before ordering.

Brushed vs Brushless — What Are You Actually Paying For?
Both versions share the core identity of the DKR-4: detailed ABS rally bodywork, portal axles, long-travel suspension, heavy-duty drivetrain components, anti-roll bars, two-speed transmission, front recovery winch, LED lighting and the same unusual desert-rally format.
The major difference is the power system.
The brushed model uses a simpler power system and gives you the same basic chassis, body, portal-axle layout and rally hardware at the lower entry price.
It makes the most sense if the platform itself is the attraction and you expect to mix scale driving, trails and moderate-speed running rather than making outright performance the priority.
The brushless version uses a HobbyPlus / Hobbywing 2435-size 3500KV four-pole sensorless motor and MINI24 ESC with FOC control and 2S–3S support.
It is the stronger choice if the rally side of the DKR-4 matters as much as the crawler/trail side and you want the broader performance envelope immediately.
The Brushless System Is More Than Extra Speed
It is easy to reduce this decision to “brushed is slower, brushless is faster”, but that misses what HobbyPlus is trying to do with the Fortis.
The brushless model pairs its 3500KV four-pole motor with a MINI24 ESC using FOC control. That matters because a vehicle with a two-speed transmission and portal axles still needs usable response when the terrain becomes slower and more technical.
The objective is therefore a wider operating range: controlled lower-speed driving when necessary, with considerably more performance available when the truck reaches open dirt, gravel or similar terrain.
The brushed version remains the more straightforward route if that wider performance envelope is not something you need from day one.
Watch the DKR-4 Fortis in Action
Red or White?
Mechanically, the colour choice does not change the decision.
Both red and white are offered with either power system, so there is no reason to compromise on brushed versus brushless just to get the body colour you prefer.
The red Fortis gives the truck the more aggressive motorsport appearance used heavily in FairRC's promotional material, while the white version makes the dark rally graphics, bumpers, wheel arches and structural detailing stand out more clearly.
That is a visual decision rather than a performance one.
Decision rule: choose the power system first, then the colour. The difference between brushed and brushless changes how the truck drives; red versus white does not.
What Both Versions Still Give You
| Feature | Why It Matters |
|---|---|
| 1/18 scale ABS rally body | Creates the Fortis's distinctive desert-rally identity rather than another generic crawler body. |
| Solid portal axles | Increase axle-centre ground clearance while retaining a solid-axle off-road layout. |
| Long-travel suspension | Designed to absorb rough and broken surfaces rather than focusing only on slow articulation. |
| Front and rear anti-roll bars | Help control body movement when speeds rise. |
| Two-speed transmission | Allows the vehicle to move between controlled low-speed use and faster open-terrain driving. |
| 1.3-inch beadlock wheels | Support the larger 68mm rally-style tyre package and make tyre servicing or experimentation easier. |
| Functional front winch | Adds both scale realism and an actual recovery function. |
| Full LED system | Includes front lighting, roof light bar and rock lights. |
| FlySky 6-channel radio system | Provides control for the Fortis's multiple functions, including transmission and winch. |
Which DKR-4 Should You Buy?
You primarily want the DKR-4 because of its desert-rally design, portal-axle chassis, scale detailing and unusual mixed trail/rally character.
At the promotional price, it is the cheaper way into the same fundamental platform.
You already know that speed, broader throttle performance and open-terrain running are important parts of why the Fortis appeals to you.
Buying the complete brushless model also avoids immediately turning a new RTR into an electronics conversion project.
Could You Buy Brushed and Upgrade Later?
Potentially, yes — and FairRC's parts catalogue is one reason the decision is less permanent than it first appears.
The current DKR-4 product page lists the HobbyPlus / Hobbywing 2435 3500KV four-pole brushless motor and MINI24 2S–3S ESC among the available related components.
However, that does not automatically make the brushed truck the cheaper route to a future brushless Fortis.
Once separate electronics, connectors, installation time and any additional components are considered, buying the factory brushless configuration can make more sense for someone who already knows that is where the build is heading.
The brushed option is strongest when you genuinely want the brushed version — not when you are buying it only to replace major electronics immediately.
DKR-4 Parts Support Is Part of the Value
The Fortis also benefits from its relationship with the wider HobbyPlus / CR18P parts ecosystem.
FairRC currently lists dedicated DKR-4 components including finished red and white body sections, cab and body panels, cockpit components, roll cage parts, rear-light components and other chassis-specific hardware.
That matters because an RC truck intended to be driven across dirt and rough surfaces eventually needs service parts.
Our HobbyPlus CR18P Parts & Upgrade Guide looks more broadly at the drivetrain, suspension, axle, wheel and electronics ecosystem around the HobbyPlus platform.
Final Verdict
FairRC's 12% promotion makes the DKR-4 decision unusually straightforward.
The brushed Fortis is the value choice if you want the truck itself: its rally body, portal axles, long-travel suspension, two-speed transmission, winch and unusual 1/18 scale format.
The brushless Fortis makes more sense when performance is already part of the reason you are buying it. The 3500KV HobbyPlus / Hobbywing system and MINI24 FOC ESC expand what the chassis can do without requiring an immediate electronics conversion.
Red versus white is personal. Brushed versus brushless is the real decision.
