20c 4s lipo or 30c 3s lipo??

Missed that bit.

Schulze = fail, quite often, if you look at them wrong. (some people have more luck than others...).

Your lipos can put out 120amps continuous (in theory), but its the peak current draw that would kill the sculze usually, or going from forwards-brake/ standstill to forwards again is a known killer.

Your Tc3 shouldnt be putting too much strain on the esc, but, dpends on alot of things- they still programmed with the little dip switch things? I would check those out carefully to make sure nothing got upset.

Your 80amp MGms wouldnt be ideal, not without extra caps and a cooling fan or two (the MM is ~100amps and works for 1:8 scale stuff with the afforementioned mods), but the 160amp esc should be fine- MGM again? Just toning down things like start power and punch can have a posistive effect, and making sure the timing is set correctly for the type of motor- some escs are alot more sensitive to that kinda thing than others.
