Doug that chassis is made by a buddy of yours right ?
Yes, that is correct.
I am fortunate enough to be able to crawl with "T1E/Uroplatus" Silas AND "Rockshow" Mike on a regular basis here in NC. The things I've seen done with this chassis on the rocks pretty much makes it impossible to not give it a shot & a "shoutout".
But everything does/can be mounted on the chassis. It almost has to be. That is unless you are willing to take a chance with an esc or lipo taking a hit on a rollerover or big drop.
They are well-designed and I have seen them take on some big hits and come back for more. That's with everything pretty much mounted inboard though.
