What ESC is used for 3-inch traversing machine?
With the rise of traversing machine sports, 3-inch traversing machines have become the first choice of many pilots because of their compactness and flexibility. However, selecting the appropriate electronic control unit (ESC) is critical to flight performance and stability. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the ESCs suitable for 3-inch ride-through machines, and provide structured data for reference.
1. Core requirements of 3-inch traversing motor ESC
3-inch traversing machines are usually equipped with 1404-1507 size motors, and the current demand is between 15A-30A. The choice of ESC needs to take into account weight, response speed and compatibility. The following are the hot needs discussed by pilots recently:
| demand | Description |
|---|---|
| Current support | Continuous current ≥25A, peak current ≥35A |
| weight | Single ESC weight ≤5g |
| Protocol support | BLHeli_32 or Bluejay firmware, supports DShot1200 |
| Size | 20x20mm or 25.5x25.5mm mounting holes |
2. Recommended popular ESC models
According to the recent discussion on forums and e-commerce platforms, the following ESC models have attracted much attention:
| Model | Current (A) | Weight(g) | Firmware | Price (yuan) |
|---|---|---|---|---|
| Hobbywing XRotor Micro 25A | 25A/35A | 4.2 | BLHeli_32 | 120-150 |
| T-Motor Velox V45A | 45A/55A | 5.0 | Bluejay | 180-220 |
| Flywoo Goku 25A | 25A/40A | 3.8 | BLHeli_S | 90-110 |
3. Comparison of user measured data
The recent actual feedback from pilots on the above ESCs is as follows:
| Model | Response delay (ms) | Compatibility | Thermal performance |
|---|---|---|---|
| Hobbywing XRotor | 8.2 | Excellent | Good (need to add thermal paste) |
| T-Motor Velox | 7.5 | General (some motors require parameter adjustment) | Excellent (metal case) |
| Flywoo Goku | 9.0 | good | General (easy to reduce frequency due to high temperature) |
4. Suggestions on purchasing
1.Sufficient budget: Priority is given to T-Motor Velox V45A, whose high current and low latency are suitable for racing flights.
2.Best value for money: The Hobbywing XRotor Micro 25A balances performance and price.
3.Lightweight requirements: Flywoo Goku 25A is suitable for ultra-light 3-inch racks, but you need to pay attention to heat dissipation issues.
5. Future trends
In recent hot discussions, integrated solutions that integrate flight control and electronic control (such as "Whoop AIO") have gradually attracted attention and may become the standard configuration of 3-inch flying machines in the future.
Summary: The choice of ESC for a 3-inch ride-through machine requires comprehensive current, weight, and firmware support. The three models recommended in this article cover different demand scenarios, and I hope it can provide a reference for your purchase.
