Flashhobby Spaceman 30A ESC 2-4S Brushless Speed Controller, 5V/2A BEC, 35A Burst, 50-432Hz

Overview

The Flashhobby Spaceman 30A ESC is an electric speed controller for brushless RC models, specified for 2-4S battery use and featuring a 5V/2A BEC for powering onboard electronics. It supports a throttle signal refresh rate from 50Hz to 432Hz and includes multiple programmable settings for brake, battery type, low-voltage protection, startup mode, and timing.

Key Features

• Continuous current: 30A; burst current (≤10s): 35A
• Battery type options: LiPo / NiMH
• BEC: 5V/2A; BEC output capability: 4 servos (2-4S)
• Throttle signal refresh rate: 50Hz to 432Hz
• Programmable brake, low-voltage protection mode/threshold, startup mode, and motor timing
• Label markings visible on the ESC: “Electric Speed Controller”, “LiPo: 2-4S”, “Made in China”, CE and FCC logos

Specifications

Programmable Items

• Brake Setting: Enabled / Disabled
• Battery Type: Lipo / NiMH
• Low Voltage Protection Mode (Cut-Off Mode): Soft Cut-Off (gradually reduce output power) / Cut-Off (immediately stop output power)
• Low Voltage Protection Threshold (Cut-Off Threshold): Low / Medium / High
  • For lithium battery: battery cell number is calculated automatically. Low / medium / high cutoff voltage for each cell: 2.85V / 3.15V / 3.3V. Example: for a 3S LiPo with “Medium” threshold, cut-off voltage = 3.15*3 = 9.45V.
  • For NiMH battery: low / medium / high cutoff voltages are 0% / 50% / 65% of the startup voltage (initial voltage of battery pack); 0% means low-voltage cut-off is disabled. Example: for a 6-cell NiMH, fully charged voltage = 1.44*6 = 8.64V; with “Medium” threshold, cut-off voltage = 8.64*50% = 4.32V.
• Startup Mode: Normal / Soft / Super-Soft (300ms / 1.5s / 3s)
  • Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for helicopters.
  • Soft and Super-Soft startup are slower: 1.5s (Soft) or 3s (Super-Soft) from initial throttle advance to full throttle.
  • If throttle is fully closed and opened again within 3 seconds after the first startup, re-startup temporarily changes to Normal mode for quicker response.
• Timing: Low / Medium / High (3.75° / 15° / 26.25°)
  • Low timing is suitable for most motors; High timing can be chosen for higher speed.

Applications

• Brushless RC fixed-wing airplanes
• Brushless RC helicopters
