If you're looking for a 1/7 short course truck that can both hug the ground at speed and launch off jumps, the CROSSRC TR71 RC Car is worth a serious look. It blends "speed" and "off-road" into one machine, using a low-center-of-gravity 4WD layout, an adjustable battery compartment, and a solid 7075 chassis to deliver a kind of wildness that can actually take a beating. As a CROSSRC TR71 RC Truck, its goal is clear: not a tame basher, but a short course truck that can fly off jumps and tear across the ground with you.
Wildly Unleashed: First Look at the TR71
The TR71's positioning is straightforward: 1/7 low-CG 4WD short course truck. The TIGER ROAR series branding and CROSSRC 4X4 appear on the body and packaging, paired with the brand slogans "BE THE BEST" and "KEEP FIGHTING." This is clearly not a tame entertainment vehicle in character.
Three color options are available: red, metallic gray, and blue. Regardless of the livery, the CROSSRC TR71 RC Truck's visual center of gravity sits very low, and combined with the wide-body stance typical of a short course truck, it already looks ready to sprint before it even moves.
Dimensions and Stance: Large Scale, Low Center of Gravity
The TR71 is a standard 1/7 large-scale short course truck. Its length reaches 702mm, width 346mm, wheelbase 426mm, tire diameter 138mm, and tire width 58mm.
With a 702mm length and 346mm width, it's noticeably larger than the common 1/10 scale vehicles. The 426mm wheelbase, paired with 138mm diameter and 58mm wide tires, ensures high-speed stability while helping the body maintain its attitude during jumps and landings. A larger body means better road adaptability, while the low-CG design makes the CROSSRC TR71 more controllable in corners and on landing.
Four Independent Suspension: The Ultimate Blend of Speed and Off-Road
The TR71 uses a four independent suspension short course truck structure. The official description puts it this way: "She is the ultimate fusion of speed and off-road, drifting and flying off jumps through violently swept dust — this is a wildness that can take a beating."
This sentence basically sums up the use case for this CROSSRC TR71 RC Truck: dust, drifting, jumps, and aggressive driving. Four independent suspension lets each wheel respond independently to road irregularities, making it easier to keep the body stable on landing and providing more direct road feedback during low-slung handling.
Power and Top Speed: 70km/h on 6S, Adjustable Up to 95km/h with Gearing
The TR71's power setup is quite impressive. It's equipped with a Hobbywing 1650KV 4985 motor and a Hobbywing 150A brushless ESC, features gyro functionality, comes RTR with a 15T pinion gear, and can reach 70km/h on 6S.
More importantly, it supports top speed adjustment by changing the pinion gear. 14T corresponds to 64km/h, 15T to 70km/h, 16T to 76km/h, 17T to 82km/h, 18T to 86km/h, 19T to 91km/h, and 20T can reach 95km/h.
In other words, from 14T to 20T, you can find the right balance between 64km/h and 95km/h depending on your track, battery, and driving needs. The gyro function further lowers the barrier to high-speed control, making the CROSSRC TR71 more stable on straights and exiting corners.
Adjustable Racing / Long-Range Layout: One Truck, Two Personalities
One of the more interesting aspects of the TR71 is that its battery compartment supports switching between racing layout and long-range layout.
In long-range layout mode, the battery compartment measures 162mm long × 48mm wide, and the battery box is adjustable front to back. You can adjust the vehicle's front-rear center of gravity based on battery capacity, giving it better attitude during off-road cruising. This mode suits longer cruising and casual off-roading, balancing the front-rear center of gravity by adjusting battery position, making the CROSSRC TR71 RC Truck more stable and enjoyable in non-extreme conditions.
In racing layout mode, the battery compartment measures 98mm long × 48mm wide, with the battery laid flat on both sides of the chassis, further lowering the center of gravity and making extreme handling more "effortless." The racing layout places the battery lower and closer to both sides of the chassis, directly lowering the vehicle's overall center of gravity. For players chasing cornering speed and extreme handling, this layout makes the CROSSRC TR71's body respond faster with less roll.
4mm Thick 7075 Chassis: Sturdy, Reliable, More Forgiving
The TR71 uses a 4mm thick 7075 chassis. The 7075 hard-anodized treatment makes the chassis sturdier and more reliable, increasing the margin for error during airborne maneuvers and providing better controllability across different surfaces.
For a short course truck that can jump and be driven aggressively, chassis thickness and material directly determine whether it can "take it." The 4mm 7075 chassis plus hard-anodized treatment gives the CROSSRC TR71 RC Truck a solid foundation for its wild driving style.
Metal Arm Mounts and Heavy-Duty Suspension Arms: Ground Feedback and Landing Absorption
The TR71 is equipped with a heavy-duty suspension arm set, connected to the chassis through all-metal arm mounts. The official description states: it provides direct road feedback during low-slung handling, and through material ratio tuning, offers better cushioning and absorption when landing from jumps, ensuring the chassis is sturdy and reliable.
The 7075 hard aluminum arm mounts, combined with the heavy-duty suspension arms, let this CROSSRC TR71 find a balance between low-slung speed and airborne landings. It won't lose handling feedback from being too soft, nor will it transmit landing impacts directly to the chassis from being too hard.
Summary: Who Is the TR71 For?
The CROSSRC TR71 is a clearly positioned 1/7 low-CG 4WD short course truck. It suits players who want large scale, high speed, jumping capability, drifting ability, and a sturdy chassis with adjustable layout. Want 6S violent top speed? It can do that. Want long-range off-road cruising? It can do that. Want a racing layout with a lowered center of gravity? It can do that. Want the solid feel of a 7075 chassis and metal arm mounts? It has that too.
The TR71's wildness isn't the kind shouted through slogans — it's built layer by layer from the chassis, suspension, power system, and battery layout into something that can "take it." If you like short course trucks and want one that can fly off jumps and tear across the ground with you, the CROSSRC TR71 RC Truck deserves a spot on your shortlist.
BE THE BEST. KEEP FIGHTING. TIGER ROAR. CROSSRC TR71.
