I've thought about doin this to an FLM chassis to lower its CG... Just hard for me to justify cuttin up a perfectly good $100 chassis ... Any way you could post some close ups of how the boxes are mounted? Maybe some vids too ...
Nice build man... lowering the FLM Chassis transforms the Maxx into a entirely new truck... what shock/spring combo are you using now?
I Have an FLM mod too that has been a whole lot of fun... you can see it in my sig below.
