If you're a high enough HR, get yourself either the Akantor bow (the upgraded one) or the Abominable bow II. Bring lots of potions, mega potions, attack and defense boosters, mega juices, etc. Keep to his RIGHT. this is very important as he has an attack where he sweeps the field with his forearms repeatedly, and he starts on the left. Basically, your aim is to get in a piercing headshot whenever you can. Just after a lightning beam or while paralyzed or trapped are the best opportunities. Sleep bombing is a good (albeit somewhat cheap) way to deal good amounts of damage. You can even get a set with adrenaline and get yourself felyne heroics and do the old self-bombing trick to jack up your stats to superhuman levels. Rajang is a tough son of a bitch though, so don't be surprised if he slaps you around like a ragdoll on your first couple of tries. Hope this helps, and if there's anything I missed, feel free to sound off.
