I recommend being extremely careful flying around areas where a Yuti may spawn, as it’s roar attack will send your flier into a frenzy and potentially into danger. To tame, try trapping it and shooting tranq arrows or darts (I wouldn’t recommend anything else as this may either 1. Waste materials, or 2. Damage the Yuti so it either loses taming effectiveness or kills it) into its side/back, as the head does more damage instead of more torpor. These are great fighters and amazing for boss fights, especially when paired with Daeodons for healing!
It really is that simple though, they can't reach you or your flier on a big enough rock, so if you don't want to make a trap you can just shoot down from a rock or cliff once the carnos are dealt with. Be ready for a goose chase once it starts running.
