Tamiya TL-01 alternative long arm set

thingiverse

This is an alternative long arm set for the Tamiya TL-01. The original long arm set by Tamiya is expensive to obtain and difficult to find. The original set also utilizes various parts from other chassis models, and if one of those parts breaks, you typically need to purchase a complete parts set for that particular model. Most of the parts in these sets are unusable for the TL-01, making it an expensive and wasteful option. To address this issue, I have developed an alternative long arm set that replicates the geometrical results of the original Tamiya set while utilizing most of the stock TL-01 parts. This set requires only one additional M3x20mm bolt per arm, which are readily available at local hardware stores and affordable. I recommend reviewing my other designs for replacement steering hubs that complement this set. Please note that your printer's tolerances play a crucial role in achieving dimensional accuracy with these arms. They are designed to fit snugly, eliminating the typical Tamiya play. You may need to run a 3mm drill through the holes for the hinge pins to ensure smooth movement. However, do not modify the outer hinges, as the M3 bolt requires threading. When installing the suspension pins, exercise caution during the first insertion, as my black PLA material is somewhat brittle and has resulted in broken arm ends due to over-tightening. Reaming the holes with a drill bit may help prevent this issue (focus on the side where the pin threads in). Some minor filing or sanding might be necessary to achieve smooth movement, but you can expect significantly reduced play in the suspension compared to original parts. **Disclaimer** This long arm set is not intended for competitive use, despite my confidence in its reliability and durability. If it fails during your racing endeavors, do not blame me.
