I finally got around to working on this project last weekend. I still need to mount another battery tray, make a rear chassis brace, and make a top brace for the diff/motor mount.
Specs:
Mamba Max
9XL
15/46 gearing
12 cell (for now)
Castle Creations BEC
Here are the pictures of what I've got done so far.
Motor Mount
Cut the throttle servo portion off to make room for the batteries and mounted electronics.
I drove it around on 6 cells and was quite surprised, I can't wait to get it finished. I've been doing the crawler thing for so long I forgot what speed was.
