I really feel like this needs to be said: Take a look and search around the forums a bit before you make a new thread. At this point the three most recent posts in the trick section have a name close to gyro flop. As yoyo13 mentioned, his thread already had a lot of info. I believe that the other thread is nothing made to help out.
And now, to mention the mighty search button. I am not saying that it’s a bad thing to make a new thread, I’m saying that there is a lot of help in older threads. So if you search for gyro flops (remember to search in the forum) you will get a lot of results that may help you out.
Addment: Gyro flops has to be one of the tricks that gives the most questions.
