(NEED HELP) How to use notepad to edit model size for MDL

[Shadow-Scythe-R]

I just downloaded this model from somewhere and imported it into my map. Big deal, but it's WAY smaller than a wisp and i dont want to use scaling value to increase the size. (Because orb effects grow bigger as well) Furthermore, i dont have 3dsMax or Gmax to increase model size. Can anyone give me a quick tutorial about how to edit its size in notepad while in MDL form?
