Kyosho Reveals New TF7 Sedan

Kyosho Reveals New TF7 Sedan

Kyosho’s TF7 is fully loaded and ready to race with features like Kyosho’s Velvet shocks, a gear rear differential, front spool and aluminum turnbuckles. We really like the red anodized aluminum parts on this sedan, it really stands out from the rest. Check out the long list of trick stuff that this sedan has to offer below.

From Kyosho:

The new Kyosho TF7 Competition Touring Car is undoubtedly the most advanced and sophisticated design in Kyosho history, and may well be the most advanced car on the market. A combination of updates and innovative yet simple new design features, deliver a package that has world-class performance potential. No expense was spared with the TF7 – it uses parts and materials that are ideal for the application, making performance the number one priority over bean-counter budgets and marketing plans to ensure the highest amount of sales. Let there be no mistake – the TF7 is simply made for fierce competitors that insist on the highest standards of quality and performance.

 

CHASSIS

The most important feature of the new chassis is what’s not there. There’s no battery mount on the lower chassis, nor is there a servo mount. The battery pack and steering servo have been mounted directly to the chassis plate on most cars for decades, but in a “what took so long to think of that?” moment, Kyosho has suspended the battery pack and steering servo from bulkheads that are mounted on the car’s centerline. A closer look shows how the battery and servo are suspended just above the lower chassis plate, which accomplishes two major advantages. The battery and servo are separated from the main chassis plate, which resolves some issues with asymmetrical flexing of the chassis. In other words, mounting the battery and servo to the lower plate can cause the chassis to flex more in one direction, and not the other. With a similar motive in mind, the TF7’s battery and servo mounts are attached to the lower chassis exactly on the center-line. This allows the carbon fiber chassis plate to be completely symmetrical, which makes the chassis flex much more predictable, and therefore, the handling is more responsive and predictable.

The lower chassis plate is milled from 2.25mm carbon fiber, and the upper plate is 2.0mm milled carbon. As previously stated, the chassis is completely symmetrical, making it flex very consistently no matter where you are on the track. The carbon shock towers measure at a robust 3.5mm thickness, which provides a solid, durable mount for the updated shocks.

 

SUSPENSION

The shorter shocks feature the famous “Velvet” coating, but the shocks are not just about the coating. The precision of the manufacturing is at such a high level, that it combines with other features that have earned Kyosho a reputation for building the best shocks in the business. Machined aluminum AND molded spring perches are included with the TF7. The shocks are fitted to low-profile 3.5mm thick carbon shock towers, which lower the CG and cause the spring rate to build more rapidly, making it ideally suited to touring car racing. Extensive testing revealed that shortening the shocks by 2mm resulted in the best handling characteristics for both asphalt and carpet racing.

The suspension arms, C-hubs and steering knuckles are made using a special molding process that infuses molded composite with long fiber strands, into these components. This is in contrast to machined aluminum or machined plastic parts that are often found on other cars. The fiber filled molded composite parts have an exceptional strength-to-weight ratio as compared to machined plastic or aluminum parts. The machined plastic is easier to break, and the machined aluminum is often heavier, which increases unsprung weight. Only molded, fiber-filled components can offer so much strength without adding unsprung weight; a critical consideration to produce the ultimate in performance.

The suspension arms are attached to the chassis using a system similar to that which debuted on the TF5 touring car. Aluminum mounts use molded eccentric inserts to tailor the toe angle and suspension widths to your exact preferences. There’s an obscenely wide range of settings for this part of the suspension, so there’s no way to miss the set-up due to a limited range of adjustment. The suspension mounts themselves can also be shimmed to alter the dive/squat geometry.

 

 DRIVETRAIN

 The belt drive of the TF7 doesn’t look much different from a distance, but the details prove otherwise. A super-precise Panaracer 64P spur gear delivers power to the machined aluminum, Velvet coated drive pulleys. These pulleys are larger diameter so more teeth on the belt are engaged with the pulleys. This reduces wear and improves efficiency.

The TF7 does not include conventional ball differentials. The rear of the TF7 features a precision, lightweight gear differential. These have become standard with the increase in the power output of brushless racing motors. The diff housing features an O-ring seal, and two O-rings sealing each outdrive. The rear drive system includes lightweight aluminum outdrives and aluminum driveshafts with “pucks” that fit over the dogbone end of the driveshaft and allow it to smoothly move within the slotted outdrive.

At the front end of the TF7 is a “rigid axle.” The rigid axle provides the most solid, instant acceleration of any other option, and it delivers exceptional braking power when compared to a front ball differential or a one-way diff and/or belt drive. The rigid axle then transmits the power to the durable “double-jointed” steel front axles, which provide excellent tight turning ability, and exceptional reliability.

Eccentric inserts affix the diffs into the bulkheads, and they allow the static driveshaft angle to be adjusted for more or less suspension movement under acceleration and braking.

Required for Operation: brushless electric motor, electronic speed control (ESC), rechargeable racing battery of your choice, a compatible battery charger, 2-channel radio system, steering servo, 190mm sedan body, touring car wheels and tires.
