Update March 19 2024: I have added a 2.0 version of the upgrade kit to the file set as a complete zip file. All of the files to make the upgrade kit are in the 2.0 zip file along with a list of changes and improvements which are as follows:
Bruticus Upgrade kit 2.0 - Changes and additions
Also I have uploaded a separate model set that utilized the left over trailer and converts it into either a Big sword or a Massive Gatling Gun with ratching barrel.

I was inspired by the design done by LikeToys for Jinbao's OS Gravity Builder Aka Devastator. I wanted my Jinbao OS KO of Warbatron Aka Bruticus to match heightwise and the new asthetic as well. So I came up with this upgrade kit that give the Combiner a great deal more height and a more MP asthetic. Check out all the video and photos and make sure to read through all the notes. Also the better the compression on your springs the better the hold on the joints will be.
