to mod or not to mod

[shizzon]

with my MMM on the way im starting to worry about it failing when i use it, so should i just do the mods as soon as i get it? I dont want to mess up the warranty with Castle, but i would like to have a working esc for longer than 10 min. I am also fairly confident in my soldering skills, by no means pro but not horrible either.

Thanks!
