4200XL replacement ESC's recommendations?

[Lil Giants]

Sabertooth 2x12 for the tracks
E-Flite for the pump... I use a 30amp in my JD850, but this retarded china setup with its excessively large motor running at 20% it's so retarded I don't know what amp to suggest... I think what's in there is 125amp & it still blows up

china electronics are crap, no thermal protection, which I guess is why they're so cheap. You're lucky it didn't start on fire.

I use a Sabertooth on the swing motor too, it's the smoothest esc I've used to date. The 2x25 is smoother yet & more precise than the 2x12.

I put quality before price... I'm sure others will chime in with cheaper alternatives that'll get you by.
