ARC A11 Split Upper Deck Rear Graphite 2mm by Factory Pro O-ARCP06  [FP-O-ARCP06]

Split Upper Deck Rear overview

This is a RC-scale split upper deck rear designed for the ARC A11 chassis, produced as an aftermarket replacement by Factory Pro O-ARCP06. The part is a 2mm graphite plate formed to replace the standard rear upper deck section while keeping the split configuration used on the original chassis.

Functionally, the rear upper deck affects local torsional stiffness behind the radio tray and influences rear-end behaviour under cornering load. Swapping to this graphite plate provides a different stiffness profile that technicians use to tune mid-to-high speed rear traction and chassis balance without altering suspension geometry.

Installation is straightforward for experienced model builders: remove the existing rear upper deck and transfer any required mounts or spacers to the replacement part, align the split sections, and secure using the original fasteners. Check clearance around the motor, servo, and radio tray before final tightening.

Tuning notes: increasing rear deck stiffness tends to reduce rear roll and may improve traction transition at corner exit, while a more compliant deck can aid traction on low-grip surfaces. Use incremental changes and test runs to evaluate handling differences; this plate is intended as one option in a broader setup process.
