The Reefs RC XP Dual Dig Transmission has been designed for those demanding smooth, consistent front and rear dig control on custom rigs. (Patent Pending)
This 3-position dig unit features a patent-pending "Revolve" dig plate design, engineered for positive engagement and seamless transition between drive and lockout. Unlike other current systems, the Revolve design eliminates the need to bump the throttle forward or reverse to disengage. Engagement and release are clean, immediate, and predictable.
The XP Dual Dig Transmission features a built-in 22% overdrive and each unit includes genuine Reefs aluminum servo horns for precision and strength.
Pair it with REEFS 99 micro servos to unlock all three dig positions (Drive, Free-Wheel and Locked) and experience smooth, consistent engagement without the typical bind or hesitation. .. in competition environments, that level of control can be the difference between a clean recovery and costly penalties.
Built for serious crawlers who demand precision, reliability, and competitive advantage.
