田宮 42391 1/10 RC遙控車 TRF421X 底盤套件
The TRF series welcomes a new TRF touring car chassis kit. This R/C model assembly kit creates the 2 beltdriven 4WD TRF421X, the latest model in the line of TRF (Tamiya Racing Factory) chassis. Based upon the racing feedback, it employs the updated suspension and low center of gravity setup for superior performance.
【About the Model】
This is a 1/10 scale R/C chassis assembly kit.
Comes with a dedicated carrying case for the TRF421X chassis kit.
Please note that this chassis requires separately sold body, battery pack, motor, tires, wheels, and R/C equipment.
<<New features>>
【Aluminum motor mount】
Motor attachment position is 1.04mm lower than that of the TRF421 chassis kit for a lower center of gravity and more stable cornering, and a new design ensures accurate assembly.
【2.0mm thick aluminum lower deck】
The new lower deck is molded in popular aluminum, and allows lower motor attachment position for optimum balance of chassis flexibility and weight distribution.
Compatible with the TRF421 chassis kit when using new motor mount and 2.0mm thick aluminum lower deck together.
【Upper deck】
Both types (one-piece and two-piece) of upper deck shape are updated for improved chassis flexibility.
Compatible with the TRF421 chassis kit
【One-piece upper deck attachment】
Tubes, dedicated titanium low head screws and shims are used to attach the one-piece upper deck. Adjust flexibility by using 0-0.3mm shims.
Compatible with the TRF421 chassis kit.
【Upper and lower suspension arms (new material) & front and rear damper stays】
Damper attachment positions are moved 1.0mm inside with new front and rear damper stays based upon the latest racing test results.
Both upper and lower suspension arms are molded in carbon reinforced nylon (the TRF421 chassis kit features glass reinforced nylon) to ensure suspension flexibility and to improve stability on high temperature or high grip or carpet surfaces.
Compatible with the TRF421 chassis kit when changing both damper stays and suspension arms.
【Drive shafts & drive train】
New front double cardan drive joint shaft and rear lightweight aluminum universal shafts feature bearings (Drive shafts used on the TRF421 chassis kit feature swing shaft caps.) to limit friction and speed reduction.
The design and materials of front direct cups and rear differential steel joints are also changed. (Materials are changed from aluminum to steel.)
Like the TRF421 chassis kit, direct coupling and oil-filled gear differential are employed at front and rear respectively. (Currently-sold Hop-Up Option and Spare Parts can be used.)
【Upper arm mounts】
New upper arm mounts feature 1mm narrower pivot attachment width for improved cornering response, and upper arm attachment with bushings to adjust pitching, ensure accurate assembly and stability under vibration.
Compatible with the TRF421 chassis kit.
【Knuckle arm】
New knuckle arms – developed based upon the latest racing test result – feature new hole positions for front and rear respectively. The hole for front makes ackerman position outward for more direct steering and the hole for rear makes adjuster rod attachment positions backward for optimum rear grip on low or middle traction surfaces.
Compatible with the TRF421 chassis kit. When using knuckle arms included in the TRF421 chassis kit, 4 setup options (2 choices for front and rear respectively) are available depending upon road surface and driving style. Sta
【Stabilizers】
Precision stabilizers can be chosen from 1.2 diameter (x2) and 1.3 diameter (x1) depending upon road surface and driving style.
Compatible with the TRF421 chassis kit.
【Receiver weight & battery weight】
Newly added receiver weight (20g) and 0.6mm thick battery weight (30g) ensure optimum weight balance. Receiver weight is attached by one screw, and also works as cooling fan mount.
Both receiver weight and battery weight are compatible with the TRF421 chassis kit.
