Hobby Plus DKR-4 Fortis 1:18 4WD Brushless Rally Truck RTR White #HBP1810820-WH

The Fortis is designed for drivers who want more than a conventional mini rally car. Its two-speed transmission, long-travel suspension, portal axles and brushless FOC power system allow it to handle both slow technical terrain and faster rally-style driving on gravel, dirt and other mixed surfaces.

The model comes as an RTR package including a FlySky 6-channel 2.4 GHz transmitter, 2S 7.4 V 1100 mAh LiPo battery and USB charger.

3500KV Brushless FOC Power System

The biggest difference between this version and the brushed DKR-4 Fortis is the 2435-size 3500KV brushless motor paired with a Mini24 sensorless FOC speed controller.

FOC, or Field Oriented Control, provides very smooth motor control at low speeds. The system can automatically adjust motor output to help maintain a consistent speed when climbing or driving over obstacles.

This gives the Fortis precise low-speed control for technical trail driving while still providing enough performance for faster rally-style driving.

The ESC supports 2S and 3S LiPo batteries. A 2S 7.4 V 1100 mAh LiPo battery with XT30 connector is included in the package.

Two-Speed Gearbox – From Technical Trails to Rally Driving

The DKR-4 Fortis features a remote-controlled 2-speed transmission with neutral position.

Low gear is designed for slower and more technical off-road driving, where precise throttle control and torque are important.

High gear provides more wheel speed for gravel roads, dirt tracks and more open Rally Raid-style terrain.

The combination of a two-speed gearbox and FOC brushless power system makes the Fortis much more versatile than a conventional single-speed mini RC truck.

Portal Axles and High Ground Clearance

The Fortis uses solid portal axles at the front and rear.

Portal axles increase ground clearance around the axle housings and help the truck travel over ruts, rocks and uneven terrain.

Ground clearance is approximately:

• 45 mm under the chassis
• 30 mm under the portal axle

This gives the DKR-4 significantly more off-road capability than a conventional 1:18 rally car.

Long-Travel Suspension

The DKR-4 Fortis uses a long-travel suspension system designed for mixed off-road terrain.

The oil-filled threaded shock absorbers allow the suspension to work smoothly over rough surfaces, while factory-installed front and rear anti-roll bars help reduce body roll during faster cornering.

A set of hard and soft springs is also included, allowing the suspension setup to be adjusted for different driving conditions.

Functional Rally Raid Hard Body

The detailed ABS hard body is inspired by full-size desert racing and Rally Raid trucks.

Several of its scale details are also functional:

• Tilting cab for easier access
• Opening rear side compartments
• Two usable full-size spare wheels
• Functional electric front winch
• LED headlights
• Roof-mounted LED light bar
• Integrated rock lights underneath the front of the vehicle

The result is a model that combines scale appearance with real off-road functionality.

Heavy-Duty Metal Drivetrain

The DKR-4 Fortis uses reinforced metal drivetrain components designed to cope with off-road driving and the additional power of the brushless system.

Heavy-duty components include metal drive shafts, axles and metal ring-and-pinion gears.

This gives the drivetrain additional durability when driving on rough terrain and under higher loads.

Where Can You Drive the DKR-4 Fortis Brushless?

The Fortis is designed primarily for mixed terrain and off-road driving.

Suitable surfaces include:

• Gravel roads
• Hard-packed dirt
• Forest trails
• Sand
• Small rocks and uneven terrain
• Backyard and garden off-road courses
• Scale and trail driving
• Rally Raid-style tracks

The combination of 4WD, portal axles, long-travel suspension, two-speed transmission and FOC brushless power allows the same model to be used for both slower technical driving and faster rally-style driving.
