Complete ULTRON 4WD buggy kit €2895,00


Deposit €500 and € 2395 on delivery.

A high-end 1/6th scale competition off-road buggy. 
With 15 years of largescale racing expirience, one and a half year of developping and testing, N-R-P is taking large scale 4wd racing to the next level with the Ultron buggy. 
A complete radical and new design compared with the existing brands. Using only the best materials currently available.


The car is a few steps ahead of the competition, With our pivot-ball front upright we can reach an unseen suspension travel of 130mm, Ultra big bore and long shocks for stability on all surfaces, Easy acces to the differentials (6 bolts max to remove the differential) to simple setting up the car. 
Changing anti-squad an toe-in with 1 single set of bushings, no need to buy extra parts, With our design you can set 1°, 2°, 3° anti-squad, and combine this with 1°, 2°, 3° toe-in just by turning the bushings in another angle. 
50-50 weight balance ratio to achieve the best handling abilities.


A body-shell designed specially for this model, cold air is sucked in on the front and the hot air is blown out by the engine at the rear. No matter the temperature outside, your engine and elektrics will stay cool.

While the car has been designed for racing purposes, the car is also home in the hobby market. 
The car is designed in a way that wrenching is brought to the mimimum. 
All parts are verry easy to acces, and the car is re-build easy compared with other high-end racing models. 
High durability and low maintenance is also an asset of the Ultron, high quality bearings, gears, driveshafts is a strenghth of the car.

You like the car, but you don't like the buggy and prefer a more realistic looking car? 
No problem, At the end of March the Ultron is also vailable as a Short Course Truck. 
The car is build out of the same parts, and quality material as the buggy, The Short Course only differs from the buggy by it's longer chassis, longer driveshafts, wheels and bodyshell.

2 Small stering servo 40x20x37 mm.

The Body

We've seen quite some comments on facebook and forums about our bodyshell.
It is a radical look, some guys like it, some guys don't, can't do anything about that.

But another points we read was the complaining about the bad quality of Grafil bodies.
We know about what happened in the past with Grafil bodies, and we know we should not make the same mistake.
For this reason we opted for a 2mm thick body shell, and no sharp edges in the design of the body !

And there was yet another points, the body is too compact, will generate too much heat.
We ran this body shell now with only a few holes inside the shell and can tell you the design works brilliant.
The engine is rotated 180° compared with other brand, wich makes the pullstarter be at the front of the car.
Fresh air gets sucked inside thrue the pullstarter, and blown out on the other side.
We designed the body shell in a way that the hot air get blown out straight away. 
No circulation of hot air inside the body shell.
Keeping your engine and elektronics cool in any condition !








Easy wrenching and maintenance

Everything in the Ultron is designed to be light, strong, and every driver/hobby bob should be able to build it.
The most important part of the setup is the differential setup. 
You don't want a car where you have to take half the car appart just to change your diff oil viscosity.
For the center differential, you only remove 4bolts on the diff carrier, you loosen the tank for an extra amount of play on the driveshaft.
(depending on exhaust type you need or don't need to remove it) And your diff is out !
Front & rear diff it's a matter of removing the bumpers, the lower wishbone carrier, the 4 diffcarrier bolts and there you have it.
Easy and quick wrenching / maintenance !




Adjustable brake pads

The ultron is provided with a seperate front & rear brake, both on a different servo.
This makes it possible to use brake mixing and adjusting the brake balance while running on track.
The brake material is made by a company specialised in cluth/brake material for 1/1 racing cars.
No more fading away of the brakes after racing 10minutes, stability is everything !

If you get some play after some time of racing, they are easy re-adjustable by 2 screws on the outside.
Adviced it to give the brakes arround 0.4mm play (between disk and brake pads)






Pivot-ball steering hubs

The Ultron is the first largescale car to be equiped with this kind of front hubs.
Thanks to this design we can reach an unseen amount of suspension travel & droop.
The inside of the hub is a steel ball, surrounded by 2 bronze inserts.
The amount of play is adjusted by large screws on the outside of the hub.
If the brons will wear out after a while, just tighten the outside screws and your good to go again !




Adjustable caster & bumpsteer
