TLR goes from “ready to run” to “Ready To Compete” with a factory-built works machine

TEAM LOSI RACING 22SCT RCT BY HORIZON HOBBY

I've seen the concept of complete RC vehicles grow since its beginning in the 80s. Originally, there were dealer “combos,” which included a kit, radio, charger, and all the other necessary gear. This evolved into nearly everything needed coming right from the manufacturer with a pre-built vehicle. Fast forward to today's modern RTR and you have everything you need, everything you might want later, and even a few things you never thought about. TLR stands for “Team Losi Racing,” so it's no surprise that they've placed an emphasis on racing with their ready-to-run model, the 22SCT RTC; that's “RTC” as in “Ready To Compete,” and the truck arrives packed with race-worthy gear. Standard equipment includes a 17.5 brushless system you can make the A-main with, and finishing touches like tire compounds and bodies you find on pro-level trucks, leaving only the battery option to the racer. Rather than packaging the RTC to meet a broad spectrum (pun intended) of users that could do anything with it, TLR aimed it directly at those planning to compete.

TOP-NOTCH RADIO GEAR

A Spektrum DX2L radio system comes with the 22SCT RTC and has all the usual trims and dual rate but adds endpoint adjustments for both channels as well as a throttle limiter option for new drivers.

TLR includes a Spektrum DX2L transmitter that provides all the usual adjustments plus a couple extra. Alongside features like the steering trim, throttle trim, and dual rate, you'll find endpoint adjustments for each direction on both channels as well as channel reversing and even a throttle limit switch that sets the top speed to Low, Medium, or High. The transmitter is paired with one of Spektrum's SR3250 micro receivers that's not only extremely lightweight, but has a super small footprint so it won't take up a lot of room in your truck.

Out back, the rear hubs give you five options for outer camber link mounts. You can raise or lower the outer link mount by adding shims behind the ball stud.

TLR's 12mm large-bore shocks are standard issue on the RTC and feature nitride-coated shafts for smooth operation. The truck also comes with a full set of shock pistons to give you plenty of tuning options.

COMPETITION-LEVEL SUSPENSION

The gull-wing front arms on the 22SCT allow for longer suspension travel without raising the shock tower's center of gravity.

One of the biggest things that makes the 22SCT RTC great is the same thing that makes all 22SCTs great, its pro-level suspension geometry. The RTC features a gull-wing front suspension that lowers the shock tower's center of gravity and allows the suspension to have longer overall travel. The entire suspension is supported by heavy-duty 4mm turnbuckles and you'll find 12mm large-bore shocks on all four corners.

HI-PERFORMANCE BODY


The name Ready To Compete is right on the money. The 22SCT RTC comes with a preprinted Hi-Performance body just like the ones the TLR team drivers use. It comes complete with shark fins and number plates, and there are marked out vents that you can cut out at your discretion.

TRACK-READY TIRES


The truck comes fitted with Losi Kingpin tires with medium compound rubber up front and soft in back to balance out the truck with its box stock setup. TLR includes a set of yellow bead-locks installed and throws in yellow dish wheel covers in the box for a different look.

RACING SPEED CONTROL AND MOTOR

The RTC gets its power from a Dynamite Platinum 17.5T motor. The motor is all aluminum and has adjustable timing for when you want to crank up the power.

A Dynamite Platinum-sensored speed control is included with the RTC and features both blinky and timed profiles for spec and modified racing.

The RTC's power system is another place where TLR has packed in the value. The truck comes complete with a Dynamite Platinum-sensored speed control that's good for up to 13.5 motors and features a blinky and timed profile for spec or mod racing. To get you started at the track, the truck comes with a Dynamite 17.5 motor that has adjustable timing and plenty of power to run with the best. The spare parts bag also includes a spare sensor wire in case yours goes bad—a nice touch to a well-thought-out combo. Since battery technology changes by the month, pack choice for the RTC is left up to you.

HARD-ANODIZED ALUMINUM CHASSIS

The same 22 platform can be found under the RTC and features a 2.5mm-thick aluminum chassis. The chassis layout features an adjustable battery box that allows for stick or shorty packs to be moved fore and aft to tune weight distribution. Like all 22 vehicles, the 22SCT RTC can be built to run rear- or mid-motor configurations, but you'll need to purchase the mid-motor tranny cases separately. The entire chassis is narrow for better handling and places the speed control on a radio tray above the battery.

Setting up the 22SCT RTC

The 22SCT RTC comes set up out of the box with a solid “baseline” setup on it that will work well for most outdoor tracks around the country. While the truck is truly competitive out of the box, you'll want to make adjustments to further tailor the truck to your specific track. Here's what I've adjusted on the RTC to dial it in for indoor 17.5 racing.

TIRES- Losi's Kingpin tires are designed for all types of dirt surfaces and their compound selection for the RTC offers both ample traction and long wear. For the hard-packed and manicured clay surface of an indoor track, I installed a set of M3 (soft) compound Pro-Line Ion tires and added traction compound.

FRONT SHOCKS- The front geometry works well, and I was surprised how sharply the truck cut in on steering input. The factory-installed piston and fluid choices work well but with the addition of softer compound front tires, the truck had more front bite, which upset the chassis during quicker back-and-forth sections. To resolve this, I went to the included #60 pistons in the front shocks, which kept the front end from rolling over as quickly.

REAR SHOCKS- The truck handles very well out of the box, but as the track's rougher sections continued to break up, the RTC was bounced around and would step out if you didn't tread gingerly through the rhythm section. I lightened up the shock with 25wt fluid.

CAMBER LINK POSITION- Tightening up the front end reduced steering response slightly, mostly on the sweeper at the end of the straightaway, so I moved the rear camber link to the innermost hole on the shock tower and outermost on the hub. I also added a .020-inch spacer under the outer ball stud to help with high-speed steering and make the rear more forgiving.

OVER JUMPS, THE RTC IS SPOT ON AS IT STAYS LEVEL AND PREDICTABLE. IN THE AIR, IT'S ONE OF THE EASIEST SC TRUCKS TO CONTROL THAT I'VE DRIVEN.

The 22SCT RTC comes with everything you need to race except the battery, so I installed a ProTek RC 7000mAh 100C pack and headed Wolcott Hobby and Raceway in Waterbury, CT. After a few slower laps to get familiar with the truck, I picked up the pace to find that the 22SCT is as easy to drive fast as it is slow. The included Dynamite brushless speed control and motor combo have plenty of power to run with the field, but the truck was still under-geared for the track. Switching to a 76T spur gear fixed things up and I had plenty of top-end for the straightaway without over-heating the motor. Over jumps, the RTC is spot on. It stays level, is predictable every time, and is one of the easiest SC trucks to control in the air that I've driven in some time, a testament to the truck's balance and weight distribution. I opted not to vent the body since I was racing indoors and in 17.5, where speeds aren't as high, but having that option in the box is nice. After our photo shoot, I took the truck to Wolcott's windier outdoor facility. The vents are well-placed throughout the body and jumping is as well-mannered as it was indoors. Steering is what this SC truck does best and considering that TLR vehicles have always aired to the side of overall traction, the 22SCT rotates very nicely—it's controlled but precise. The included high-torque servo has plenty of torque and speed, and when matched with the balance of the soft compound rear and medium compound front tires, the truck turns solidly lap after lap. Through tighter areas of the track, the RTC feels very nimble with sharp steering response, but through the rhythm section, the truck is easily upset and gets out of control unless you ease up on the throttle a bit. However, moving the rear camber link inward on the tower and a lighter shock setup resolved the problem for me.

Similar to most Spektrum radios, the DX2L is well-balanced and feels very familiar. It's quickly adjusted by pulling over on the track and turning the rotary knobs, and while it tends to be more on the basic side, it's certainly on the top of it. For the basic racer, the guy who has raced for a while but doesn't get into the finer side of transmitter tuning, it will serve well. When you're ready to upgrade to a higher-end digital radio like Spektrum's DX3R Pro, the RTC's included receiver is compatible.

+

  • Race-ready right out of the box

  • Well-balanced stock setup

  • Competition-level electronics

-

  • No mid-motor transmission case

  • Soft compound front tires would be more raceworthy

FINAL WORD

As someone who races and has spent countless hours and endless dollars on racing gear, it's always been a dream of mine to be able to go to the hobby shop, purchase something, and put it immediately on the track—my situation with the 22SCT RTC was exactly that. You only need bring $540, a charger and battery pack. The rest is up to your driving skills. The truck includes nearly everything you'll need plus some exciting extras. With a proven platform and quality gear, this vehicle is the ultimate club racer.

Associate Editor I can say that I’ve never done ANYTHING as long as I’ve been into RC. I got my first car when I was 11 and never looked back. Since then I’ve owned hundreds of cars and trucks and raced everything from Off-Road to Boats but I’m an Oval racer at heart. Whether I’m down siding a jump or going fast and turning left, it’s all on and my foot is to the floor! I love seeing new people discover our hobby and helping anyone I can enjoy it more. When I’m not racing or writing, I like to restore vintage RC cars and organize the Vintage Offroad Nationals. I’m also a dad and enjoy teaching my son how to drive and watching him get into this hobby on his own.
