Fox full hop dair shine vs Falco not working?

[smashquestions12]

Me: Fox

Them: Falco

How come whenever my full hop dair hits Falco, I get shined? I am trying to dair and then shine. When I practice solo on 20xx I am not missing my L-cancels. Is full hop dair to shine not guaranteed (excluding SDI/ASDI)? Or am I just constantly missing my L-cancel in this situation in tournaments?

 

[reverie2]

it's guaranteed, unless you either miss your l cancel, or your last dair hitbox comes out misses (because they di'ed out of it)

 

[smashquestions12]

Thanks. By the way, if the Falco was in the air from a short hop (from lasering or an aerial, for example) is it still guaranteed (assuming the dair connects all the way to the ground / the Falco doesn't DI out of it)?

If you hit someone with a drill when they are in the air when they hit the ground they get out of hitstun as far as I recall

If your opponent is in the air and gets drilled, by the time that your drill ends and you L cancel they will be actionable before you can shine.
