This is the SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit. The S104 EK1 includes a variety of interesting design features that are unique to 1/10 scale 4wd buggies, including pivot ball front suspension, 14mm 1/8 scale style wheel axles with large diameter wheel hex adapters and wheel nuts, as well as a rear battery mount that can accommodate either a 2S LiPo saddle or 98mm shorty pack! Other features include an incredibly narrow aluminum chassis with a weight forward component layout, and silver carbon fiber shock towers. Plus, the rear shock tower features a unique design that incorporates a lower aluminum camber link brace for added rigidity. 14mm aluminum body, threaded big bore shocks will soak up the bumps and hard landings, and the mud deflectors help protect the shock shafts and seals from dirt and other contaminants.

Two aggressively shaped cab forward bodies are included, one for saddle packs, and one for shorty packs, as well as add-on polycarbonate dirt shields that attach to the main chassis plate and help to keep the chassis free of contaminants. Another innovative feature that is included as standard equipment is the SWorkz X-system transmission. The X-system is incredibly durable and delivers excellent acceleration. Combine this with oil filled gear differentials and the S104 EK1 will provide good traction and balance on any off road track.

SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit
This car is incredible! It has a ton of steering and traction. Its extremely durable and well built. The only negative is the limited space for electronics. I own all the Sworkz vehicles and they are all top notch. Is this car better than the b44.1 or b44.2? Yes!! I have run almost every 4wd buggy and this is hands down the fastest and the smoothest. People are trying to say its like a durango...No way! I ran a durango and the durango cant even touch this car. I run on low to medium bite clay track and this car is stupid good. If you are running on this type of surface get the softer springs and go way softer than the shock oil they supply.)

SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit
Great buggy! I bought the combo and performance chassis together, I needed 10th scale electronics and I'm happy with the purchase. The kit builds nicely, (no e clips or pin retainers) and comes with some extra parts in the box, thanks sworks! I've run it on super hard packed indoor red clay and it competes. The car really shines on outdoor red clay, first time out on a new to me track I set the TQ for the day on my first run, also took 1st overall in the mains. It accelerates and stops quick, and turns smooth on a dime. I run it with a shorty pack and the motor in the back (performance chassis and motor mount), by just flipping the diffs in their housings, and motor mount (purchase or make a shorty strap). The car is durable, only part showing wear after five complete racedays is the center slipper rear outdrive ($5 part). Just take your time when building, with the nature of 1/10s, many screws are short so you could strip a hole easily. Buy it, you WILL like it especially with the performance chassis.)

SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit
Awesome car! The gear diffs and gear case are beautifully designed. It is literally a shrunk down 1/8 e buggy. The car has tons of droop with front and rear droop screws, the suspension is very plush. I weighed it on 4 scales and it is very balanced. The carbon fiber is of great quality. The car has great turn in and will rotate and pivot on command. The steering is very linear and precise. All the cvd joints are captured and all the hing pins are capture like an e buggy. There are inserts for the hing pin holders to adjust anti squat, toe in, kickup ect ect...... The car is very easy to drive and is very well manured. The new breed of 1/10 wheelers has arrived......)

SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit
I have been into off road racing for over 20 years and have had every name brand from Losi, Associated, Kyosho, and even Tamiya. Hands down this is the best kit I have ever built. The kit comes with a lot of extra parts, directions that are spot on, and the build went together smoothly. I am simply amazed at the 1/8 scale similarities. It has huge bearings in the front and rear diff. The carrier bearings in the hubs are extremely large and thick as well. No more diff balls, stripping nuts, and breaking diff bolts. This kit has massive diffs filled with oil. I recently sold my fragile belt slipping Losi 22-4 and purchased this buggy and will most likely buy all of their products from now on. SWorks didn't just step up to the plate with this buggy, they knocked it out of the park. A very satisfied consumer, Jody....)

We are running this car on high grip carpet here in Norway.
The Xray xB 4 is not any faster.

SWorkz S104 EK1 1/10 4WD Off Road Racing Buggy Pro Kit
Impossible to make a acceptable setup for carpet and Astro :-(( to much steering, and a rear roll center definitively to high !!!
very disappointed by this car, not comfortable, not sure, to nervous around neutral I regret my Yokomo more drivable. since two races I became a "B" main driver...it's a pity...since 3 years, I was a "A" main driver with my "old" Bmax2...
I'll change for another car in 2014, looking for the new Bmax3 or HPI D413, clearly with a better conception ;-)

Good luck to all if you run on high grip track...and if you can, don't bought this car...excepted if your name is "Masami, Naoto, mayfield or Cavalieri"...LoL...I'm not, I'm just a human...not a E.T...

Best regards from France ;-))
