With the Rev 1, I would suggest getting the extra long 15" handles or longer. This will allow you to actually flic the kite easier. Shorter handles just don't have enough throw to really get the Rev 1 to flic. It can be done but it takes a very sharp snap and a little work.
One of the main things that helped me with my flic-flac was to move my feet.

When you get ready to do your flic, snap your wrists firmly and at the exact same time, take a good sized step towards the kite. What this will do is give your top lines enough sudden slack that the wing tips can flip over. Without stepping forward the kite will kinda flip up horizontal like and then either snap back down or just plain go wacko.
Think of it like trying to do a flic flac on a dually without giving any slack.
