RC Excavators

The dream of all RC farm and construction vehicle enthusiasts is surely to own an RC excavator, there is nothing more satisfying than to be able to load a trailer on your diorama with your RC construction equipment. RC excavators are probably the most complex conversion to attempt because they have a lot of moving parts and the hardest part is raising the diecast boom which is usually very heavy even with an empty bucket.

RC Hitachi Zaxis 210

My first RC excavator was a Hitachi Zaxis 210 made by ROS, I tried to use servos to control it and quickly learned how difficult an RC excavator build is.


RC Komatsu PC400LC

My second excavator is a Komatsu PC400LC made by Joal, this time I used N20 gear motors to drive screw mechanisms.


Liebherr A900C Litronic

The third excavator I converted was a plastic Revell kit of a Liebherr A900C Litronic, the lighter plastic body makes this an easier conversion.
