Product overview
The FlashHobby Spaceman 100A ESC, item 300100, is a brushless motor speed controller intended for helicopter and airplane installations. Its hardware combines motor control with a switching BEC rated at 5V/7A, making servo-power provision part of the controller configuration. The unit weighs 80.90g and measures 85 × 36 × 9mm, defining its physical integration footprint. For a 3–6S configuration, BEC output capability is specified as 6–8 servos. Throttle-signal refresh rates span 50Hz to 432Hz, while current ratings distinguish 100A continuous operation from 120A bursts lasting no more than 10 seconds.
Configuration options cover braking, LiPo or NiMH battery selection, startup response, motor timing and low-voltage protection. Normal, Soft and Super-Soft startup settings correspond to 300ms, 1.5s and 3s; Low, Medium and High timing settings correspond to 3.75°, 15° and 26.25°. Low-voltage protection can gradually reduce power or stop output immediately. Lithium cell count is calculated automatically, with selectable per-cell cutoff thresholds of 2.85V, 3.15V and 3.3V. NiMH thresholds instead use 0%, 50% or 65% of initial pack voltage, with the 0% setting disabling low-voltage cutoff.
