• Motor Rotation Direction Control — Easily reverse motor rotation direction (clockwise or counter-clockwise) to match your installation requirements without rewiring or mechanical changes.
• Three Running Modes — Choose between Forward/Brake, Forward/Brake/Reverse, or Forward/Reverse modes depending on your application and driving needs.
• Flexible Reverse Mode Options — When running in Forward/Brake/Reverse mode, select between One Shot (single throttle pull to activate reverse) or Two Shots (quick double throttle pull for reverse engagement).
• Automatic LiPo Cell Detection — The automatic cut-off voltage setting detects the number of LiPo cells when powered on, protecting your battery from over-discharge damage whilst maintaining performance.
• Thermal Protection — Selectable thermal protection thresholds (95°C or 105°C) automatically stop the ESC if internal temperatures exceed safe limits, protecting your speed controller from heat damage during extended running sessions.
• ET0106 Programming Card Included — The programmable setup card is included with this ESC, allowing you to access and adjust all sixteen parameters without requiring additional software, computer equipment, or specialised knowledge.
• Compact and Lightweight Design — Measuring just 48 x 38 x 32mm (without cooling fan) and weighing only 95 grams, this ESC takes minimal space in your RC car's chassis, making it ideal for tight installations in various 1/10-scale vehicle types.
