How much weight can Trx4 lift? In-depth analysis of its performance and hot topic correlation
Recently, the topic of off-road vehicle performance and modification has continued to rise across the Internet. In particular, Traxxas Trx4 is a popular remote control off-road vehicle, and its load capacity has become the focus of many players. This article will combine the hot topic data of the past 10 days and use structured analysis to answer the question "How many pounds can Trx4 lift?" and explore the technical principles and practical application scenarios behind it.
1. Trx4 basic performance parameters

As the flagship remote control climbing vehicle of Traxxas, Trx4 is designed with both off-road performance and load capacity in mind. The following is its core parameter table:
| parameters | numerical value |
|---|---|
| Original motor | Titan 550 (21T) |
| Torque output | About 3.2kg·cm |
| gear ratio | 11.39:1 (low gear) |
| Vehicle weight | 2.8kg (original configuration) |
2. Actual measured load capacity data
According to recent measured data from player communities (such as RCCrawler, Bilibili, etc.), the load performance of Trx4 under different configurations is as follows:
| Modification status | Maximum towing weight (catties) | Test conditions |
|---|---|---|
| Original factory configuration | 8-10 pounds | flat cement road |
| Upgraded motor (35T) | 12-15 pounds | 30 degree slope |
| Additional weight + metal transmission | 18-22 pounds | off road terrain |
3. Correlation analysis of hot topics
In the past 10 days, discussions related to Trx4 load capacity have mainly focused on the following aspects:
1.Motor modification controversy: Some users believe that replacing a high-torque motor (such as HH Crawlmaster) can increase traction by 50%, but opponents point out that this will sacrifice battery life.
2.Battery selection: The explosive power of the new LiPo battery has become the focus, and the 5000mAh 3S battery has been confirmed to increase the traction margin by about 3 pounds.
3.tire modification: RC4WD’s 1.9-inch mud-terrain tires have been liked more than 20,000 times on the Douyin platform. Actual tests show that their grip can improve load stability.
4. In-depth interpretation of technical principles
The load capacity of Trx4 is mainly affected by three major factors:
| Influencing factors | Mechanism of action | Optimization plan |
|---|---|---|
| Gear transmission efficiency | Low gears amplify torque | Replacing steel gear set |
| Center of gravity distribution | Affects traction transmission | Install front axle weights |
| Motor heat dissipation | High temperature causes power loss | Install cooling fan |
5. Practical application scenario cases
1.rescue trailer: A popular YouTube video shows that the modified Trx4 successfully towed a 15-pound 1/10 scale simulated rescue boat.
2.Outdoor transportation: Domestic players shared on Weibo that they used Trx4 to transport 6 pounds of camping equipment, and it worked continuously for 2 hours without overheating.
3.competitive games: The competition rules exposed on the Reddit forum require participating vehicles to have at least the ability to drag 20 kilograms of sandbags.
6. Suggestions on purchasing and modification
For players who want to increase the load capacity of Trx4, it is recommended to give priority to the following modification parts:
| Part type | Recommended brands | price range |
|---|---|---|
| High torque motor | Holmes Hobbies | ¥400-600 |
| Metal drive shaft | Hot Racing | ¥200-300 |
| Weighted hub | SSD | ¥150-250 |
Conclusion
Taken together, the towing capacity of the original Trx4 is about 8-10 kilograms, which can be increased to more than 20 kilograms through reasonable modification. The recently hotly discussed motor cooling solutions and new tire technologies provide players with more optimization options. It is recommended to balance performance and durability according to actual needs to avoid component loss caused by excessive modification.
