Forward Thrust Control
Press the button down to engage forward thrust. The deeper you press, the higher the PWM output and the faster the speed — it is proportional control, not just on/off. Pressing fully to the bottom gives maximum throttle; releasing the button (spring-back) stops the output.
Applications
-
DPV & Underwater Thrusters – Speed control for diver propulsion vehicles
-
Brushless ESC Testing – High-voltage ESC and thruster testing
-
DIY Brushless Cooling Fans – Manual speed control for high-power fans
-
DIY Car Wash Equipment – Speed regulation for pump motors
-
RC Boats & Marine Models – Simple waterproof throttle control

Simple ESC Matching Guide
Voltage (V):
ESC voltage = Battery voltage (e.g., 3S LiPo = 12V, 6S LiPo = 24V).
Current (A):
ESC current ≥ Motor max current + 20-30% safety margin.
Quick Examples:12V, 20A motor → 30A ESC (or higher).
Rule: ESC can handle higher amps than needed, but never lower. Always check motor specs!
