Castle Creations & Ghost RC Cobra 8 ACE ESC - Drag & High-Speed
The Ghost RC Cobra 8 ACE is a high-performance electronic speed controller designed specifically for 1/10 No Prep Drag Racing. Built on Castle's proven Cobra 8 platform and enhanced by Ghost RC, it offers advanced launch tuning, timing control, and data logging features for racers looking to fine-tune every aspect of their setup. With a powerful adjustable BEC, waterproof construction, Castle Link programmability, and Ghost RC's exclusive drag racing firmware, the Cobra 8 ACE delivers the flexibility needed for today's competitive drag racing applications. 🔥KEY FEATURES 32-bit processor for smoother motor control and improved throttle response. Enhanced data logging with higher sampling frequency, longer recording time, electrical timing monitoring, onboard accelerometer data, looping logs, and downloadable sessions. Adjustable internal BEC from 5.0V to 8.0V in 0.1V increments. Castle Link V4 USB programmer included for free firmware updates and programming. Optional Bluetooth programming with the Castle B-Link 2 interface (sold separately). CRYO-DRIVE technology helps improve thermal performance during partial throttle operation. Premium CNC aluminum case with waterproof epoxy potting. Premium forged heatsink for improved airflow and heat dissipation. Auxiliary wire functionality for transmitter-controlled adjustments. Audible diagnostic alerts for common ESC conditions. Designed and manufactured in Olathe, Kansas, USA. DRAG RACING FEATURES Enhanced Start Power provides increased control over launch performance. Start Power Ramp Time adjusts how quickly launch power is applied. Start Power Hold Time controls how long Start Power is maintained before transitioning into Boost Timing or Programmed Throttle. RPM Limiter allows a maximum motor RPM to be set, helping reduce rotor failures if driveline components fail. Boost Timing adds up to 120° total motor timing using RPM-based or throttle percentage activation (sensored operation required). Turbo Timing provides additional timing after Boost Timing with adjustable activation point and programmable degrees-per-second ramp rate. Programmed Throttle Curve automatically engages a user-defined throttle curve after launch. Upgraded 8 AWG Battery Wires are designed for high-current drag racing applications. 📦WHAT'S INCLUDED Ghost RC Cobra 8 ACE ESC Castle Link V4 USB Adapter 300mm Direct Connect Sensor Wire ⚙️TECHNICAL SPECIFICATIONS Application 1/10 No Prep Drag Racing Input Voltage 2S–4S LiPo (6.0V–16.8V) BEC 5.0V–8.0V adjustable in 0.1V increments, 8A Peak (default 5.5V) Running Modes SmartSense Brushless, Sensored Only, Brushed Brake Proportional Reverse Yes (can be disabled for racing) On/Off Switch Yes, waterproof Cooling Fan Optional Dimensions 60 × 52 × 43 mm (2.36 × 2.04 × 1.69 in) Weight 165.6 g (5.84 oz), without battery connector Motor Connectors 6.5mm Female Bullet Connectors Waterproof Yes Data Logging Yes Telemetry Not Supported B-Link Compatible Yes DOWNLOADS User Guide Quick Start Guide Motor Quick Start Guide Audible Alert Reference Chart ESC Mounting Template IMPORTANT NOTES An external capacitor pack must be used with the Ghost RC Cobra 8 ACE.
