Tamiya USA TB Evo.7 Details + Release

42315 TB EVO. 7 Chassis Kit
Release Date: October 20

This is the 7th generation TB EVO chassis. The new look TB EVO. 7 takes this chassis series, which is the pinnacle of Tamiya shaft-driven 4WD, in a brand-new direction: multiple selectable motor positions, the removal of an upper top deck with a stiffener used on the chassis deck in its place.

Features:

•1/10 scale shaft-driven 4WD chassis assembly kit.
•The chassis is based around a 2mm thick aluminum lower deck and 6mm thick center stiffener, which give a blend of rigid pitch damping and flexible roll. The number of screws used to attach the stiffener can be changed to alter chassis rigidity.
•The lack of an upper deck lowers the chassis’ center of gravity.
•A largely overhauled layout includes updated motor positions and bulkhead design.
•The motor is longitudinally mounted. Users can choose from 3 layouts (front; mid; rear) to adjust performance depending upon track conditions and driving style.
•Equipped with TRF super short big bore dampers.
•Motor clearance can be adjusted simply from above, for quick in-pit tweaks.
•Steering linkage components are installed directly onto the bulkhead as opposed to being attached to the chassis. This removes any effect upon chassis roll.
•Highly-efficient shaft-driven 4WD is achieved with a front direct coupling and WO universal shafts, plus a rear gear (oil-filled) differential unit and aluminum drive shafts.
•Equipped with TRF418 suspension arms and TRF419 rear uprights.

Specifications:
Length: 371mm
Width: 185mm
Wheelbase: 258mm

TRF Report JMRCA Championship 2017

TRF (Tamiya Racing Factory) driver Takayuki Kono was at the recent JMRCA Touring Car All Japan Championship 2017 with Kiyokazu Suzuki to provide support for Tamiya users, and he got some racing in too!

2017 JMRCA Touring Car All Japan Championship
July 21st – 23rd, 2017
Keitune Racing Speedway, Chiba Prefecture, Japan

Top class drivers were out in force at the Keitune Racing Speedway on a hot July weekend, ready to do battle in the 2017 JMRCA All Japan Championship 1/10 touring car races. No less than 65 racers took part in the event, which featured Super Expert and Open classes.Tamiya Racing Factory (TRF) driver Takayuki Kono was in attendance, welcoming the chance to put the freshly-announced TB Evo.7 chassis through its paces against some of the best drivers out there. Also present was TRF member Kiyokazu Suzuki, ready to dispense advice and answer questions from Tamiya fans and drivers.

This was the official racing debut for the TB Evo.7, and while Kono largely used the pre-race test runs to compare the TB Evo.7’s different motor positions, when the race came he was on the pace with his competitors, qualifying in 10th for the Open class A Main. Starting from the back of the A Main field was always going to be a challenge, but Kono proved the shaft-driven TB Evo.7’s capabilities with a sterling drive that saw him mix it with the rest of the grid on his way to an 8th place finish over the 3 final races.

The Open class saw more great news for Tamiya chassis, 2016 Tamiya World Champion
Shuma Shinozawa finishing a brilliant 2nd with his TRF419X.

Takayuki Kono: “It was great to have the opportunity to demonstrate the potential of the TB Evo.7 and its shaft drive in live competition. The smoothness of the steering in particular is something for the public to look out for, and I hope this has whetted everyone’s appetite!”

TRF looks forward to continuing to support R/C drivers and the industry through its activities.

·   The steering system is connected to the front uplight via the center link. Ackerman’s adjustment can be adjusted by changing the bush of the upright arm (2 types).

·   The front pulley is arranged at the center of the carbon chassis and it is balanced in symmetrical symmetry It is excellent in maneuverability.  Pulley is using material with less friction with the belt. The reduction ratio of the pulley (34T / 20T) is 1.7.

·   Drive shaft is universal type for both front and rear.  The front is a double joint type
It is made of steel.  The rear is made of hard alumite treatment with aluminum.

·   The shock case is subjected to hard alumite treatment and excellent in abrasion resistance, silicone oil is hard to get dirty  Maintaining stable performance.  The shock upper tip nut is subjected to laser marking Can indicate the count of silicone oil.

·   Carbon front upper deck and rear upper deck control chassis roll
It is Ultraflex type.

·   The front and rear bulkheads are made of aluminum material and have high finish accuracy. The front solid axle and the rear differential are adjusted by the eccentric hub to adjust the belt tension Attach it to the bulkhead.  With lower finish accuracy also lower arm mount, replace bush You can adjust the angle of the lower suspension shaft.

·   Motor mount is made of aluminum material and lightweight.  Installation is at center of chassis   Fix with 5 screws in symmetrical position.

·   The body mount adjuster can adjust slightly the body mounting height by changing the direction.

Tamiya TB Evo.7 First Picture

A first official picture of the upcoming new Tamiya TB Evo.7 Chassis.

From the pictures we can see:

– alu chassis, no upper deck, but possibly a mid alu spine
– ball bearing held roll-bars (finally Tamiya!)
– 419X suspension and dampers
– mid motor position obviously
– alu bulks as should be on a TB Evo
– steering system/arms seems to be turned around
