[senty]

Go with 3300kv and you can gear up if you need more speed.

Neither

Wouldn't the 85amp get hot on those motors?

Get a blx100 and 3200 kv from jennys.

My thoughts exactly. But, nobody's addressed the power module and slipper clutch.

I may have some extras I'm not gonna use laying around some where!?

This.

Neither of those is a good match for any of the Arrma 4x4 1/10 rigs. You want the 100 amp esc and the 3200kv 3660 motor. If those are your only 2 options save up to buy the proper system. IMHO putting the 85a esc and those 3650 motors in the 4x4 platform is like buying an 80s Mustang with a 4 cylinder in it and expecting it to be a good performer.

My 120A ESC from Hobbywing (Ezrun max10 sct) and 3200kv 3660 motor have been bullitproof.
