I don't  know what's causing the Sabertooth 2x25 to go nuts in one of my
tanks. All  of the sudden, and even when teh batteries are fully charged, it
goes  insane.  Usually what it does is it goes reverse at full speed and  jams
there.  If I kill the power from teh killer switch, it resets and  is
"collaborates" with my RC. I installed a 12 V fan on 18V current blowing  air
on the ESC and still does teh same unpredictable tricks. I now wonder  if it
is affected by shocks and vibrations or if there is a short  circuit
somewhere . I checked for teh latter again and again. Couldn't find  a  leak.

we had a similar problem in my dad's one submarine, the rudder servo  would 
just peg all the way over to one side BUT this only happened when we were  
testing it in the one neighbor's pool, but if i went to another neighbor's 
pool,  
there was no problem. it only happened in the one pool.
 
is it possible something in your tank is effecting it? maybe some rare  fluke 
with your radio system or main power feeds? any other wires come close to  
the speed controller unit or the wires leading to it?
 
did you try this unit in something else to see if it still does it?
 
possessed tank?
