1. Introduction
The Tamiya TRF Body Sponge Tape Set 42331 is designed to provide a secure and protective interface between your R/C car's polycarbonate body and its urethane bumper. This tape helps to eliminate gaps, thereby protecting the body from damage during impacts and reducing unwanted "wobble" for improved driving stability.
2. Product Components
The Tamiya TRF Body Sponge Tape Set 42331 includes the following items:
- One (1) sheet of 2mm-thickness sponge tape (20mm x 230mm)
- Two (2) sheets of 3mm-thickness sponge tape (20mm x 230mm)

3. Setup and Installation
Follow these steps to properly install the sponge tape on your R/C car:
- Prepare the Surfaces: Ensure that the inner surface of your R/C car's polycarbonate body and the contact surface of the urethane bumper are clean and free from dust, grease, or debris. A clean surface ensures optimal adhesion.
- Identify Gaps: Place the R/C body onto the chassis and identify areas where there are gaps between the body and the urethane bumper. These are the areas where the sponge tape will be applied.
- Select Tape Thickness: Choose the appropriate thickness of sponge tape (2mm or 3mm) based on the size of the gap you need to fill. Thicker tape is suitable for larger gaps.
- Cut to Size: Carefully measure and cut the sponge tape to the required length to cover the identified gap areas.
- Apply Tape: Remove the protective backing from one side of the sponge tape. Align the tape precisely with the desired application area on either the inside of the polycarbonate body or the urethane bumper. Press firmly along the entire length of the tape to ensure good adhesion.
- Test Fit: Re-mount the R/C body onto the chassis. Check for any remaining gaps or areas where the body still feels loose. Apply additional tape as needed to achieve a snug fit.

4. Operating Principles and Benefits
Once installed, the Tamiya TRF Body Sponge Tape functions by creating a cushioned barrier between the R/C car's body and its chassis components, primarily the urethane bumper. This provides several operational benefits:
- Body Protection: The sponge material absorbs impact forces, protecting the polycarbonate body from cracks and damage, especially during collisions or rollovers.
- Reduced Wobble: By filling gaps, the tape ensures a tighter fit of the body to the chassis, significantly reducing unwanted body "wobble" or vibration during high-speed driving or cornering. This contributes to more stable and predictable handling.
- Extended Body Life: Minimizing direct contact and friction between the body and chassis components helps to extend the overall lifespan of the R/C car body.
5. Maintenance
To ensure the longevity and effectiveness of the sponge tape and your R/C car body:
- Regular Inspection: Periodically inspect the sponge tape for signs of wear, compression, or detachment.
- Cleaning: If the tape becomes dirty, gently wipe it with a damp cloth. Avoid using harsh chemicals that could degrade the adhesive or sponge material.
- Replacement: If the tape shows significant wear, loses its cushioning properties, or begins to peel off, replace it with new tape to maintain optimal protection and stability.
6. Troubleshooting
Here are some common issues and their potential solutions:
| Issue | Possible Cause | Solution |
|---|---|---|
| Tape not adhering properly. | Dirty or oily surface; insufficient pressure during application. | Clean surfaces thoroughly before application. Apply firm, even pressure across the tape. |
| Body still wobbles after tape application. | Incorrect tape thickness; insufficient coverage; tape has compressed over time. | Ensure correct tape thickness for the gap. Apply tape to all contact points. Replace worn tape. |
| Body difficult to mount/remove. | Tape is too thick or applied in excess, creating too tight a fit. | Remove some tape or replace with thinner tape (e.g., 2mm instead of 3mm) in critical areas. |
