I have decided to keep some of the previous owner's "modification work" to the battery tray and electrical shelf he set up. There were some odd holes drilled in the battery tray for which I could see no purpose for, so I drilled it out further to even it out and lighten it a bit. "As if" it will make a difference on the weight. These were pretty heavy machines. Totally overbuilt motors! So, I drilled some more holes, cleaned up the bends, and rounded all the edges down... then cleaned the plates up. I will primer them with some great aluminium aircraft stuff I have then paint or powder coat them black to match the frame. It will actually look pretty nice and function very well when all is said and done.
