What am i doing wrong? Kage TFT Combo help

I can't nail this combo on Lei Fei at all
TFT – FC,f+K – P – f+P+K – ub+K+G
[80]

The flipkick always wiffs. Do i have to delay something for this to work??? /versus/images/icons/confused.gif

 

There's 2 things I can think of -- either you've got too much of a delay on the flip kick, or Lei Fei is too heavy for the combo to work.

 

After the knee, you must hold forward while in the air and do the as soon as you land. You must then do the ++ as soon as possible, followed immediately by the ++
