This dual output ESC is very good value when compared to most others out there and avoids the problem of overloading a single motor unit or trying to run two in parallel.  
 
Only thing to note:  This does not come with a connecting plug, just cables that have been tinned with solder - ready to fit your own Tamiya or Deans-style connector.
