An external cap would help a bit, needs to be 25-35v, low esr, 105*C, 2000-4000uf.

A small fan would also help; both these mods are 'bread and butter' things you do to the MM to make it work in a 1/8 setup, I wouldnt use it otherwise and just buy a proper 1/8 esc to start with instead..

As for swapping the diffs to lower the ratio, that would actually work rather well, but then you still cant gear to high otherwise temps climb, so the mods mentioned above need to implemented. Mike sells caps, as do Tekin, or hit up DigiKey.
