ESC for 4wd and 2wd

[spiro]

I'm in the process of purchasing new ESC's for both my race cars, the B4.1 and B44.1. In my old rides I have a Speed Passion GT in the B4, and an Orion Vortex for the B44. The SpeedPassion is bored beyond belief, but the Orion is really ready for some eggs and bacon to fry. I have no idea why my B44 renders the Orion this hot, and I've tried different pinions to lighten the load. I've noticed that even the motormount is extremely hot. Even hotter than the motor itself. Tried timing the motor down - no luck, still hot. In the end I had to fit cooling ribs and a fan for the B44. That really should not be needed with a Novak Ballistic 6.5 turn.

Guess the question is this - which ESC is the one to have for buggies these days? I like a smooth and gentle power curve to cater for slippery tracks.
