I made the top chassis plate with wings. I like it. I wish it was CF but I didn't have any left so it is aluminum. It is 42 grams heavier than the stock plate. I thought I had bad bearings on the truck. It wasn't the bearings, it was two CVDs with cracked and broken parts.
No more brackets for the battery boxes, the top chassis plate and small aluminum angles is what holds the boxes real solid like.
