Im almost certain it doesnt aerial stun :/. You may be able to stun them while they regrab ledge or something (testing on 3ds sucks). Lfk on platforms is really good though! When say ganon is just on the outside platforms of bf and you stun him while on the platform it sets up perfect for dair spikes :D or a juggle.Just some observations I've made after about an hour of toying around with Lightning Falcon Kick
If you manage to stun the opponent, the best guaranteed follow-ups are-
-Knee
-Up-air -> knee (depends on percent)
-Up-air -> footstool (depends on character and percent)
-Grab
-F-smash
-Footstool (fairly difficult). It might be possible to loop infinitely, but I'm not sure. So far I've been able to get it the most by spamming a short-hop input and holding slightly in the direction of the opponent
Occasionally you'll notice that you stun the opponent but do 18%, when stunning typically does 4%. This happens because the non-stunning hitbox comes out, but the stunning hitbox also comes out and stuns the opponent after they're hit with the initial attack. For some reason follow-ups out of this variation of LFK never register as being true combos in Training Mode, but I am unsure whether that's actually the case.
The best way to stun (in my experience) is to aim slightly in front of the opponent. Obviously LFK is very risky and fairly hard to stun with, so use it in extreme moderation. I would recommend using LFK on stages with platforms fairly low to the ground, like Battlefield. If an opponent (has to be somewhat tall) is below a platform, and you initiate LFK above that platform, you will usually be able to stun the opponent. This does eliminate some of your ground punishing options once you stun, however. I'm still experiment with footstooling when using this method.
Also, could someone test as to ensure that both of the variations of Falcon Kick possess the same hitlag modifiers as the original that prevent frame canceling? Can anyone confirm is it's possible to stun while using LFK offstage (although I understand that's not remotely practical)?
