S K C U R T TOP With so many short course trucks flooding the market, it can be overwhelming trying to decide which truck is your best bet. Each company has its own way of looking at truck design; as yet there’s no standard, which makes your decision a harder one because there’s so much from which to choose. While I think anyone would be happy with each of the vehicles, some choices may be slightly better at racing, while others may be a bit more durable and fun to run off the track. First things first, decide what you want to do with your truck. Do you want to race, backyard bash, or a combo of both? Once you have figured it out, you can better decide which truck is best for you. This guide shows what is available in the popular 1⁄ 10-scale class and provides insight on which truck does what the best, so you can save both time and money when you pick up that new rig. The Hottest Short Course Trucks for 2010 BY ERIC J. MILLER THE SC10 HANDLES LIKE A DREAM ON THE TRACK FEATURES TEAM ASSOCIATED SC10 QUICK SPECS PART NO. 7027 (Kit), 7026, 7028, 7029, 7030 & 7031 (RTR) PRICE $170 (Kit), $220 (RTR) KIT/RTR Both POWER Electric 2WD/4WD 2WD LENGTH 21.65 in./550mm WIDTH 11.5 in./293mm WHEELBASE 12.9 in./327mm MOTOR (RTR only) Reedy 17-turn brushed ESC (RTR only) XP SC200 forward/reverse with reverse lockout and LiPo low-voltage cutoff RADIO (RTR only) Associated XP 2-channel AM with metal gear servo The SC10 is based on a stretched version of the six-time National Champion T4 platform and comes RTR or as a kit. The RTR gives a choice of six painted bodies, while the kit offers a clear body for you to customize. Scale looks go a step further with the cool KMC-style rims and realistic treaded tires. Each corner is supported by blue aluminum shocks and steel turnbuckles for adjustability. The gear differential is sealed for future tuning and is built to withstand the plethora of powerful brushless motors on the market. PERFORMANCE Associated was one of the earlier companies to offer a short course racer. Since it is based off a 1⁄ 10-scale racing truck, the SC10 handles like a dream on the track. Overall, it feels like a race truck should—very light and nimble. The handling and steering is much better than some other trucks’ due to the T4’s proven suspension and steering geometry and the stretched chassis that places the battery closer to the front. The sealed gear diff is super smooth and is well suited to most tracks. SHORT COURSE RACING 2010 55 S K C U R T P O T HPI BLITZ QUICK SPECS PART NO 103171 PRICE $190 KIT/RTR RTR POWER Electric 2WD/4WD 2WD LENGTH 21.6 in./548mm WIDTH 11.6 in./296mm WHEELBASE 13 in. (adjustable)/329mm MOTOR:Firebolt 15T motor ESC SC-15 with reverse RADIO TF-1 2-channel AM JUMPING IS BETTER THAN WITH OTHER TRUCKS THANKS TO THE DESIGN OF THE BODY’S FRONT END FEATURES This RTR truck arrives with an HPI version of the Maxxis ATK body in either black or orange, and the sweet-looking wheels and tires really enhance the total package. A lengthened version of the E-Firestorm chassis provides the backbone for this truck. The all-metal gear transmission is bulletproof and is designed to handle as much power as you want to run through it. Aluminum 12mm hex hubs increase durability, and a setscrew keeps them attached to the axles when you remove the tires. PERFORMANCE On hardpacked dirt surfaces the truck struggles to put the power down, but once you switch to loose dirt or pavement, the tires come to life and you’ll have all the traction you could want. Overall, this truck feels planted and gives quick, consistent laps battery after battery. Jumping is better than with other trucks thanks to the design of the body’s front end; it doesn’t allow the truck to jump nose-up as much as others. 56 RCCARACTION.COM JAMMIN SCRT10 QUICK SPECS PART NO.: 14615 PRICE: $270 KIT/RTR: Preassembled kit POWER: Electric 2WD/4WD: 4WD LENGTH: 533mm/21 in. WIDTH: 279mm/11 in. WHEELBASE: 324mm/12.75 in. MOTOR: N/A ESC: N/A RADIO: N/A FEATURES Jammin’s entry into short course comes as a race roller kit. You’ll provide the electronics, but that’s all that’s needed to get the truck up and running. What makes this truck stand out from other electric trucks is its truggy-style, flat low-center-of-gravity chassis design and triple-diff drivetrain. Universal driveshafts get the power out to the included bead-lock wheels. There are a lot of adjustments in this truck to make it perform its best in all conditions. PERFORMANCE Note: At press time, we were unable to test this truck but can give you an idea of how it performs on the track thanks to videos that Jammin’ provided us. Right away, you clearly see that the Jammin’ SCRT10 can easily put down any power you throw at it thanks to the traction of 4-wheel drive. Turning is also very impressive; it seems to turn better than other trucks that are on the track with it. We attribute that to the included center diff. It jumps farther than any truck we have seen, again because of 4-wheel drive. It still, however, jumps with a slight nose-up attitude, but that can be solved by cutting air holes out of the back of the body to let air pass through and reduce that effect. IT SEEMS TO TURN BETTER THAN OTHER TRUCKS THAT ARE ON THE TRACK SHORT COURSE RACING 2010 57 S K C U R T P O T YOU’LL APPRECIATE THE SMOOTH THREADED SHOCKS ON THE DRT; THEY ABSORB BIG IMPACTS AND MAKE RUTS DISAPPEAR KYOSHO DRT (DESERT RACING TRUCK) QUICK SPECS PART NO.: 31082B PRICE: $300 KIT/RTR: RTR POWER: Nitro 2WD/4WD: 4WD LENGTH: 19.25 in./489mm WIDTH: 10.12in./257mm WHEELBASE: 11.77 in./299mm ENGINE: GXR .18 RADIO: Perfex KT6 AM with digital servos FEATURES Power from the GXR engine gets to all four tires via three diffs, similar to that of an 1⁄ 8 truggy. Parts count stays low with interchangeable A-arms, knuckles and shock towers. A large 105cc fuel tank provides the GXR .18 engine with plenty of go-juice. Dual disc brakes ensure solid fade-free performance run after run and give you adjustable brake bias. PERFORMANCE Where 1:1 meets 1:10 Full-size and RC short course racing is actually closely related. There’s definitely more going on than just scale-looking bodies and wheels. Our race tracks, for example, are quite similar. In both scales, the layouts consist of high-speed sweepers, berms and whoop sections, and the trucks even handle much the same, leaning and sliding through corners. Fender rubbing is another aspect that shows up regardless of scale. RC race classes generally consist of Pro-2 or Pro-4 trucks (based on drive wheels) just like the big boys, and a number of RC manufacturers even sponsor full-scale race teams and leagues. If you don’t have the cash or skills to get behind the wheel of a fullsize truck, you can still get in on the action with RC! Whether you drive on a track or in the wide open, you’ll appreciate the smooth threaded shocks on the DRT; they absorb big impacts and make ruts disappear. The GXR .18 engine holds a good tune and puts out strong linear power for its size. The digital servos do a good job of squeezing the binders as well as turning the front tires. 58 RCCARACTION.COM KYOSHO EP ULTIMA SC TRUCK READY SET QUICK SPECS PART NO.: 30855X-B PRICE: $210 KIT/RTR: RTR POWER: Electric 2WD/4WD: 2WD LENGTH: 17.52 in./445mm HEIGHT: 5.90 in./150mm WHEELBASE: 11.25 in./286mm MOTOR: G20 Stock ESC: Perfex LiPo-compatible RADIO: Perfex KT6 AM with KR6 2-channel receiver FEATURES The platform for the Ultima SC is a lengthened version of Kyosho’s RT5 truck chassis, and there’s a lot of room in the battery compartment for major weight bias adjustment. The bellcranks are angled to match the angle of the front suspension arms to reduce bump steer. A compact three-gear transmission and bevel-gear diff send the power to the ground. Threaded body shocks allow quick ride-height adjustment. PERFORMANCE Note: At press time, we were unable to test this truck but can give you an idea of how it performs on the track thanks to videos that Kyosho provided us. By watching the video, you can see that this truck carries over a lot of its performance traits from the RT5. The suspension soaks up small bumps and jumps very well, and the chassis stays flat in the turns. The tires seem to be well suited to various conditions and allow for some tight steering. THIS TRUCK CARRIES OVER A LOT OF ITS PERFORMANCE TRAITS FROM THE RT5 SHORT COURSE RACING 2010 59 S K C U R T P O T THE LOSI STRIKE HANDLES THE ROUGH STUFF BETTER THAN SOME OF THE MORE RACE-INSPIRED TRUCKS LOSI STRIKE QUICK SPECS PART NO.: LOSB0105 (RTR) LOSB0105BD (Bind-N-Drive) PRICE: $230 (RTR), $200 (Bind-N-Drive) KIT/RTR: RTR and Bind-N-Drive POWER: Electric 2WD/4WD: 2WD LENGTH: 22.76 in./578.1mm WIDTH: 11.65 in./295.9mm WHEELBASE: 13.68 in./347.58mm MOTOR: 12T 550 performance ESC: Water resistant with reverse RADIO: Losi Radio System (receiver and transmitter included) with Spektrum 2.4GHz DSM Technology (RTR) Spektrum 2.4GHz DSM receiver, no transmitter (Bind-N-Drive) FEATURES The RTR and BND models feature the same chassis components, but the BND lacks a transmitter but comes with a receiver, for those who already own a Spektrum or Losi 2.4GHz radio to bind to it. The Strike features a mid-motor layout for good balance. The transmission is built for abuse; the gears are all metal. Losi’s blue aluminum shocks are smooth and use threaded bodies for easy preload adjustment. LiPo users have the benefit of a built-in low-voltage cutoff in the speed control. PERFORMANCE The Losi Strike handles the rough stuff better than some of the more race-inspired trucks on the market. On the track, the truck remains planted and landed consistently and with no drama. The stock tires do a good job of hooking up on most surfaces and have major grip on pavement. Making turns is easy to do thanks to the steering geometry and strong steering servo. 62 RCCARACTION.COM OFNA HYPER 10SC PRO 4X4 QUICK SPECS PART NO: 14615 PRICE: $270 KIT/RTR: Preassembled Kit POWER: Electric 2WD/4WD: 4WD LENGTH: 533mm/21 in. WIDTH: 279mm/11in WHEELBASE: 324mm/12.75 in. MOTOR: N/A ESC: N/A RADIO: N/A FEATURES The Hyper 10SC is packed with cool features such as three fluid-filled diffs, machined bevel gears and a steel main gear, and you also get aluminum threaded shocks, adjustable swaybars and a CNC motor mount. It uses an aluminum chassis plate that is lightweight and durable and will help dissipate any heat buildup from the motor and battery pack. All the components that are mounted on the chassis sit forward for improved steering. PERFORMANCE Note: At press time, we were unable to test a truck but can give you an idea of how it performs on the track thanks to videos provided by OFNA. Of course, the Hyper 10SC accelerates harder than the 2-wheel-drive trucks in our guide thanks to its 4-wheel-drive design. The center diff bleeds off slight power but really aids in steering. The suspension seems to be right on, as the truck looks well planted on all areas of OFNA’s test track. It even jumps well and gives lots of control in the air. 2- or 4-wheel-drive? There are a variety of sweet trucks to choose from, but the basic question seems to be, “Which is better, 2WD or 4WD?” I wouldn’t say one is better than the other, but both have tons of appeal for different reasons. 2WD trucks are more affordable and usually more durable, so budget racers and bashers find it easier to get up and running. Having only 2WD also means a light, agile truck that is a blast to slide though corners without the need for massive horsepower. You will spend less time wrenching with the simple drivetrain layout and easier maintenance. On the other hand, 4WD gives the opportunity to drop in a lot more horsepower. These wild machines can take intense motor/battery combos for extreme tire shredding. They can also be easier to drive quickly if you have an aggressive trigger finger. You can expect a little extra heft with 4WD, but it adds stability on straights and through the bends. This category of truck is also designed to take tons of punishment. 4WD trucks might cost a bit more, but if you have the cash, they are hard to beat. THE HYPER 10SC ACCELERATES HARDER THAN THE 2-WHEEL-DRIVE TRUCKS IN OUR GUIDE THANKS TO ITS 4-WHEELDRIVE DESIGN. SHORT COURSE RACING 2010 63 S K C U R T P O T TRAXXAS SLAYER QUICK SPECS PART NO.: 5908 PRICE: $370 KIT/RTR: RTR POWER: Nitro 2WD/4WD: 4WD LENGTH: 22.36 in./568mm WIDTH: 11.65 in./296mm WHEELBASE: 12.7 in./323mm ENGINE: TRX 3.3 Racing Engine with EZ-Start RADIO: Traxxas TQ 2-channel AM THE COMBINED POWER OF THE ENGINE AND 2-SPEED TRANSMISSION MAKES FOR A FUN, HAIR-RAISING EXPERIENCE FEATURES The Traxxas Slayer is definitely the most unique truck in this guide with its 3D semimonocoque chassis and inboard suspension system. Powering the truck is Traxxas’ popular and proven TRX 3.3 engine, and a 150cc fuel tank feeds the carburetor. In the center of the chassis is an ultra-compact 2-speed forward-only. Traxxas gives you a choice of four painted body styles for a realistic look right out of the box. PERFORMANCE The 3.3 engine is easy to fire thanks to its on-board electric starting system, and it holds a consistent tune. The combined power of the engine and 2-speed transmission makes for a fun, hair-raising experience when you drive the truck. The tires provide good grip on asphalt and they do well in the dirt. On the pavement it’s easy for the truck to wheelie when the front end hits small bumps in the ground. The brakes do an equally good job of slowing the truck down from its impressive top speed. The GTR inboard shocks and long travel rockers soak up small bumps and jumps as if they weren’t even there. 64 RCCARACTION.COM TRAXXAS SLASH QUICK SPECS PART NO. 5805 PRICE $220 KIT/RTR RTR POWER Electric 2WD/4WD 2WD LENGTH 22.36 in./568mm WIDTH 11.65 in./296mm WHEELBASE 13.2 in./335mm MOTOR Titan 12T 550 ESC Waterproof XL-5 RADIO Traxxas TQ 2-channel AM FEATURES YOU GET THE SENSE OF REALISM AS IT LEANS IN THE TURNS LIKE A FULL-SIZE TRAXXAS TORC TRUCK. The Slash comes equipped with a brushlessready metal-gear transmission and a RevoSpec Torque-Control slipper clutch. The included XL5 ESC and digital high-torque steering servo are both waterproof, while the receiver is tucked away inside an O-ring-sealed box. Traxxas also specs its high-current connector to avoid any potential meltdowns. The Ultra Shocks are fluid-filled and use progressive-rate springs to soak up the bumps. Its high-riding stance makes it easier for backyard bashers to avoid getting high centered over obstacles. PERFORMANCE When you drive the Slash, you get the sense of realism as it leans in the turns like a full-size Traxxas TORC truck. It leaps through the air with the best of them and seems almost always to land on all fours regardless of the angle of flight. The Slash shrugs off big hits and drives away from pretty much anything you run into, including curbs! This truck seems almost indestructible. SHORT COURSE RACING 2010 65 S K C U R T P O T THE SLASH 4X4 PUTS OUT IMPRESSIVE POWER FOR AN RTR TRUCK TRAXXAS SLASH 4X4 QUICK SPECS PART NO. 6808 PRICE $399 KIT/RTR RTR POWER Electric 2WD/4WD 4WD LENGTH 22.36 in./568mm WIDTH 11.65 in./296mm WHEELBASE 13.2 in./335mm MOTOR Traxxas Velineon 3500 ESC Traxxas Velineon VXL-3S Waterproof RADIO Traxxas TQ 2.4 GHz with Mini Receiver FEATURES This truck goes in a different direction from the other trucks in the Traxxas lineup with its unique 4WD drivetrain. A lightweight blue aluminum driveshaft runs down the center of the chassis and connects to two Revo-spec siliconefilled diffs that are sure to hold up to any power source you throw at it. The truck also comes with Traxxas’ high-powered and waterproof VXL brushless system to provide the scoot. It comes equipped with a Traxxas TQ 2.4GHz radio system and high-torque digital steering servo as well as a 7-cell NiMH. PERFORMANCE The Slash 4x4 puts out impressive power for an RTR truck and easily puts it down thanks to the shaft-driven 4WD. The truck is equally at home on the track and in a backyard setting. The suspension does a great job of soaking up bumps and jumps. It has a slight on-power push in the turns. Power delivery from the motor and speed control is smooth and on point. 66 RCCARACTION.COM TRAXXAS SLASH 4X4 (PLATINUM EDITION) QUICK SPECS PART NO. 6804 PRICE $390 KIT/RTR Preassembled kit POWER Electric 2WD/4WD 4WD LENGTH 22.36 in./568mm WIDTH 11.65 in./296mm WHEELBASE 13.2 in./335mm MOTOR Traxxas Velineon 3500 ESC Traxxas Velineon VXL-3S Waterproof RADIO Traxxas N/A IMPRESSIVE ACCELERATION AND GREAT SUSPENSION ARE ENHANCED THANKS TO ITS INCLUDED OPTION PARTS FEATURES This truck has all of the same features as the RTR version, but Traxxas omits the radio and batteries but kicks it up by including blue-aluminum suspension parts, big-bore shocks, a swaybar set and a clear body for your own personal touch. This truck was built with the racer in mind, yet the extra features included with the chassis will make the basher just as happy. PERFORMANCE The Platinum has similar qualities such as impressive acceleration and great suspension when it comes to performance, but they are enhanced slightly thanks to its included option parts. The chassis stays more flat in the turns thanks to the included swaybar set, and turning is even tighter when you install the included center diff. The smooth high-end shocks make the suspension feel even better and are much more durable. Going through the twisties, you get a bit of push and then do a slight 4-wheel slide coming out of the turns when you mash the throttle. All four tires kick up a roost as they claw their way out of the corner and down the straight. Making in-air adjustments is easy by blipping the throttle or tapping the brakes.
