My BL Revo project

[BrianG]

I've been trying to figure out how to design a sturdy rollcage to protect the BL motor, tranny, and ESC and came up with this prototype:



It is just sitting on the battery tray mounts right now, but I plan to secure it to the back of the battery trays eventually. However, I don't want to use aluminum because a good hit will bend it (especially since the top is flat). Anyone have any ideas on what type of material to use?

I want something that is light and will be able to take an impact from landing on the lid (without bending) since I'm not a great driver. :)

I was thinking of bringing the design to a metal shop and having it made from spring steel, just not as thick or as wide. I want to make sure the design will work as intended first, so, I'm open to suggestions on how to make it better.
