I just bought the MGM 160 controller and the Neu motors have been out of stock what Neu or Lehner motor do you suggest for a Gorillamax Revo, would like to do 45 if I want but its mainly for bashing, I will use lipos how many cells will I need to run also? When will the Neu's be back in stock? Also do I need to use a fan on the MGM? Thanks
