Question about Warranty on my MMM

[lil3j]

Im not sure, but I thought I saw somewhere that if you alter the case that it voids the warranty on the MMM. Is this true? If not, I have some pics below. I took the fan off of my MMM so the esc could fit in my touring car. I couldnt wait on the Mamba pro to run 3s in a 4wd touring lol. But I found that if the body isn't fit to run that fast, cars tend to have "lift" at high speeds. Can someone from castle let me know if this is covered under warranty? Thanks in advance. Jonathan
