Yes i did, i get all my aluminum from Home Depot or Lowes. There is a lot you can do to an ECX Amp, it doesn't look like it, but you can do lot of mods to that truck. You just need to take the body off and look at and figure out what you want to do to it and how you can do it. I run mine with a Gen Ace 7000 mAh 70cC LiPo but had to lift the battery compartment in order for the battery to fit. My Amp is an older version and the battery compartment is part of the rear suspension so i had to some ingenuity to raise it. I use a lot of aluminum spacers to raise or push out a part on the truck. I will try and send you some pictures. Another thing i do is get rid of all the self threading screws and replace them with M3 machine screws. You can order all different sizes on eBay. You can see the spacers i used to raise battery compartment. If you look closely you can see the turn buckle is connected to the battery compartment, ence part of the rear suspension. The newer versions of the Amp are not like that, ECX changed the design so its easier now to raise the battery compartment.
