Comprehensive technical overview of XR10 Justock, XR10 Pro, Stock Spec, and classic Xerun platforms. Covering parameter explanations, zero-timing Blinky setup, and official documentation.
Homologation classification and Blinky implementation across key Xerun platforms.
| Model | Category | Zero-Timing Mechanism | Inspection Protocol | Tech Scrutineer Notes |
|---|---|---|---|---|
| Xerun XR10 Justock / Justock G3 | Hardware-Locked | Physical spec board; no timing menus exist in MCU | Visual Model Audit | Universally accepted spec controller. Cannot be modified with timing. Flashing Red LED at neutral. |
| Xerun XR10 Stock Spec | Profile-Selectable | Parameter 1A: Profile set to 0 (Zero-Timing) |
LCD Box Profile Audit | Connect LCD Program Box: confirm Profile = 0. Red LED blinks at neutral; Green on throttle. |
| Xerun XR10 Pro / Pro G2 / Pro Elite | Profile / Dual-Param | Profile 0 or Boost Timing = 0° & Turbo Timing = 0° | LCD Box / App Audit | Flagship competition ESC. Requires Profile 0 or zeroed Boost and Turbo registers. |
| Xerun 120A / 60A-SD / Xtreme Stock | Dedicated Firmware | Requires official non-timing firmware (e.g. v508_No_Timing) |
USB Link PC Query | Legacy competition platform. Must be flashed with certified non-timing stock software to activate Blinky mode. |
Detailed breakdown of core parameters based on official Hobbywing engineering documentation.
Forward / Brake: Standard sanctioned racing mode. Reverse is completely locked out so cars cannot back up into race traffic.
Forward / Reverse / Brake: Practice/bashing mode with double-click reverse engagement.
Drag Brake Force: Brake percentage applied automatically when throttle trigger returns to neutral. Simulates natural rolling resistance (common: 5% to 20%).
Drag Brake Rate: Controls how quickly drag brake ramps up upon releasing throttle.
Dynamic electronic timing advance introduced progressively across the RPM range before reaching full throttle.
In spec Blinky racing, Boost Timing must be locked to 0°. Any non-zero value activates illegal advance.
Additional electronic timing added only at 100% wide-open throttle (WOT), typically used on long straights.
Turbo Delay: Time interval at 100% throttle before Turbo engages. In Blinky mode, Turbo Timing must be 0°.
Punch Control: Limits current ramp rate during initial acceleration from standstill or slow corners to prevent wheelspin.
Softening: Fine-tunes throttle response at bottom end to smooth out aggressive modified motors.
Low Voltage Cut-off: Detects battery voltage under load and cuts or limits power to prevent LiPo over-discharge damage (typically 3.2V to 3.4V per cell).
ESC/Motor Thermal Cut: Shuts down drive if MOSFET temperature exceeds safe limits (e.g. 105°C / 221°F).
