This is an upgrade for existing RCX owners to upgrade the arm to a locking style. This can be added to your existing RCX Gen 1 with no modifications. It can be used like the old arm, with a safety.
THIS IS AN ARM ONLY, NOT A COMPLETE RCX SYSTEM
(verified owner) – June 12, 2022
The RCX Arm upgrade is a must for the older Rail Changers.
