Tamiya TRF104 Chassis Kit
-
Description
The TRF104 is a high-spec formula one chassis that takes the genre to a new level! This hi-spec 2WD formula chassis, built around carbon fiber and aluminum chassis components, with the front lower arms crafted from carbon fiber plate, makes it a formidable opponent on the racetrack! Furthermore, the chassis features updated front and rear suspension, plus an updated R/C equipment layout which is compatible with Li-Po batteries.
Key New Features:
- Updated front suspension:
- Features plastic upper A-arms.
- Camber angle is adjustable freely from +1 to -3 degrees (approximate) using a 2mm hex wrench.
- Caster angle is also adjustable at 6, 9 and 12 degrees. (approximate).
Updated rear suspension:
- Suspension link and T-bar setup are not used. Instead, ball connectors are equipped at motor mount front and rear, and suspension roll is placed at the center of the chassis.
- The model centering is controlled by roll springs under the rear shaft, and friction grease on roll dampers at motor mount allow adjustment of roll speed.
- The pitching is controlled by FRP suspension plate flex and a TRF damper.
R/C equipment layout:
- Formula chassis can lose rear grip because of unbalanced weight. To prevent this problem, battery pack, receiver and servo are positioned at the center of chassis to ensure better rear grip.
Compatible battery packs:
- A square-shaped battery holder is included, for Li-Po battery packs to comply with U.S. open-class regulations.
- Motor mount:
- Motor mount has parts for adjustment of ground clearance and wheelbase: 5 types of ground clearances are adjustable in 0.8mm steps and two wheelbases can be chosen with a difference of 2.5mm.
Steering servo & steering linkage:
- The laid down steering servo is positioned about 30mm backwards compared to the TRF103 chassis and ensures a low center of gravity.
- Features a choice of 4 types of steering linkage adjustments over a range of about 1.8mm length by changing Ackerman plate position to keep direct steering.
Rear differential unit:
- The rear differential unit is the same as the one used for the TRF103 chassis. Lightweight and durable carbon fiber shaft limits weight and ensures compatibility with rubber tires which are relatively heavy.
Two rear wing mount options:
- A 2mm thick carbon fiber plate is used to attach the rear wing. In this case, the rear wing is connected to the motor mount, and it moves along with rear suspension.
- When adding separately sold Item 53596 Aluminum Servo Stays (Short) as wing mount to attach rear wing, rear wing is connected to suspension plate, and it does not move along with rear suspension. (It remains horizontal even if rear suspension moves.)
Front suspension arms:
- 2.5mm thick carbon fiber front lower suspension arms have two attachment positions (3mm adjustment for each side) to adjust its width and attach wheels with different offsets.
- If using separately sold Item 54153 (F103 Carbon Reinforced Front Suspension Arm) and 53119 (RD Special King Pin Set), the width can be changed to the same 200mm width as the TRF 103 chassis.
