Frequently Asked Questions:
Q1. What is the primary difference between a BLHeli_S ESC and a BLHeli_32 ESC, like the FOXEER Reaper F4 Mini 45A?
Ans. The primary difference lies in the processor. BLHeli_S ESCs (like this one) typically use an 8-bit MCU, offering great performance for most pilots with protocols like DShot600. BLHeli_32 ESCs use a more powerful 32-bit MCU, enabling faster digital protocols (DShot1200+), real-time ESC telemetry, and more advanced configurable features, often preferred by competitive pilots.
Q2. Is the 45A continuous current rating sufficient for a typical 5-inch FPV drone on 4S or 6S LiPo?
Ans. For many 5-inch FPV drones, a 45A continuous current rating per motor is generally sufficient, especially for 4S LiPo setups and even for balanced 6S freestyle flying. It can handle most common 22XX or 23XX motors. However, for extremely aggressive, high-power 6S racing builds with very high KV motors, a 55A or 60A ESC might offer more headroom.
Q3. Does this FOXEER Reaper F4 Mini 45A 4in1 ESC have a built-in current sensor?
Ans. Yes, the FOXEER Reaper F4 Mini 45A 4in1 ESC typically includes an integrated current sensor. This allows your flight controller to read and display real-time current consumption from your motors, which is crucial for monitoring battery usage, calculating remaining flight time, and diagnosing potential power system issues during flight.
