I actually made my own chassis for my crt.5 and it is close to 1/8 length.
I am considering adding the wheel adapters to run 1/8 wheels with this. The nose dives you spoke of in your first post is exactly why I have the front bumper. The plastic on this tuck is not all that strong...I have broken 3 front arms so far.
