Product overview
The Flash Hobby Spaceman 40A is a brushless electronic speed controller for airplane and helicopter installations using a 2-3S configuration. Item 30040 combines motor control with a switching BEC rated at 5V/3A, with stated capacity for five servos on 2-3S. Its 65*25*12mm dimensions and 41.4g weight define the component space and mass to accommodate during integration. Continuous current is 40A, while the 55A burst rating is limited to 10 seconds or less. The throttle signal accepts refresh rates from 50Hz to 432Hz.
Configuration options cover braking, LiPo or NiMH batteries, low-voltage response, startup behavior and motor timing. Low-voltage protection can reduce power gradually or stop it immediately, with battery-specific thresholds; the lowest NiMH setting disables this protection. Normal startup is intended for fixed-wing aircraft, while Soft and Super-Soft provide slower acceleration for helicopters. Closing and reopening the throttle within three seconds after initial startup temporarily selects Normal restart behavior. Three timing settings—3.75°, 15° and 26.25°—provide additional motor-control adjustment.
