Make sure that you have enough space between the ground and a Dino in order to have that smash effect. Hitting a Dino's before landing seems to cancel the crash land instead of hitting the dino
Wanna get Wyvern eggs? Use one of these with a whip and you'll get so many eggs you'll end up with so many omelettes that you don't know what to do with them
While diving pull up at the last second above your target and use main left click attack. Does a ton more dmg then just landing on target. Gives a nice speed boost too.
