pop kicks help

[kiwarrior]

Hey fellow trickstaz!
There are two tricks, which I have problems it, hoping you can help.
The first one is the Pop 720, which I could do around a month ago(it's at about 0:30):

So, a while later I could do it with a proper kick, but now, I can only spin one and a half, and nowhere close to the 2 whole spins. When I first did the trick, it felt kinda natural and easy, but now the spin crashes, my legs throwing themselves apart, and I fell off-angle.

The second is the Feilong Kick.I can Pop 360, Pop 540, formerly Pop 720, but this apparently easy, foundational trick won't come to me. If I concentrate on the first kick, the second leg doesn't kick, and vica versa. And don't tell me, I should practice the Pop 360 more cuz I did practice it a lot, but no improvement in the Feilong.
So yeah, this is it. Help me out pls

For the Fei Long, try drill Hyper 360 pop crescents, landing on your kicking leg but holding the second, non-kicking leg chambered in front of you. It should look like tucking one leg (i.e when you're sitting, the legs are 90 degree to your body, so nonkicking leg is like this it's also similar to pumping your legs in some kicks)
First my Hyper 360 were kinda low but then it clicked :) Fast progress.
Edit: so here is the Hyper 360 found on youtube

Then for the twisting, try to keep your chin up, not looking down, that's what made my twisting techniques unbalanced. Nevertheless I can't 720pop, I just took this advice from backside 900 :D

thx, your advice sounds reasonable, i'll try it tomorrow
I guess my main problem with some kicks is that I don't chamber any of them. Maybe more aesthetical but surely slower :worry:
