Catching a Yian Kut-Ku
The easiest way to catch a Yian Kut-Ku is to get the Assassin dagger upgrade because it's fast and does decent damage. When you start the mission just make sure you have 10 potions with you and some flash bombs then get all the items you need out of the supply box and head for the Kut-Ku, just run between areas 2 and 3 until he appears in one of them. When he arrives, paintball him, then just start hacking away at him with the dagger, and a few large barrel bombs if you like. After he falls down the first time, hit him with a flash bomb, and setup the pitfall trap around him, then stand on the other side of the trap just far enough so he can't hit you with a fireball, and as soon as he steps in the trap hit him with two or three of the tranq bombs, and you have just caught a Kut-Ku! The best way to tell when a wyvern is ready to be captured is that their mouths will be smoking. Hope I could help.
