Product overview
The Flash Hobby Spaceman 80A ESC, item 30080, is a brushless motor speed controller for airplane and helicopter installations. Its physical integration envelope is 86 × 38 × 12mm, with a weight of 68.52g. The controller combines motor power control with a switching BEC specified at 5V/7A and a capacity of 6–8 servos in a 2–6S configuration. It is an electrical propulsion component rather than a complete flight platform or an airframe kit.
Electrical integration must account for the 80A continuous current rating and the 100A burst rating, which is limited to durations of 10 seconds or less. The throttle signal refresh range is 50Hz to 432Hz. Programmable settings cover braking, LiPo or NiMH battery selection, low-voltage protection, startup behavior and motor timing. Protection can progressively reduce power or stop it immediately. Lithium cutoff thresholds are specified per cell, while NiMH thresholds depend on startup voltage; selecting the NiMH 0% threshold disables low-voltage cutoff.
Startup behavior can be matched to the aircraft application: Normal is suitable for fixed-wing aircraft, while Soft and Super-Soft are suitable for helicopters. Their respective startup times are 300ms, 1.5s and 3s, with the soft-mode times covering initial throttle advance to full throttle. Closing and fully reopening the throttle within three seconds after the first startup temporarily switches restart behavior to Normal. Timing selections are 3.75°, 15° and 26.25°; Low is usually suitable for most motors, with High available for higher speed.
