Using a gyro is going to get you into trouble faster than you can get out of it, Hard to get setup and unless you put 3 in the plane you might as well not use one. The trick is to find a .40-.60 size 3D plane and really practice on that first or doenload some og the 3D setups for G-2 if you already have G-2. If not...start smallm and cheap then work your was up. The guys you see doing 3D have been thru more that on plane and probaly started on something designed to teach 3D. Personallt I prefer my Freya for 3d but that's kinda cheating.
I kinda like the bipe I came up with that has that little bit od added punch;
