there are some pics on this thread where to place the capacitor for the TC2.
I am going to sell the TC2 Cyclone (I got one coming in on a package deal) when it comes and keep an eye out there for a good esc without a capacitor or at least room for it to fit better. I am leaning very heavily towards the GM series as most of the guys here run that (there are a few cyclones, but most run the GM). Anyone else have suggestions? I am pretty set on selling the TC2 so let me know other ESCs you think are great.
