Well, for 3D G2 just is not going to get it.. If my memory serves me there is an Extra that is red, blus and yellow in G2 that is the closest thing you ca get to a 3D plane.

You really need to invest in a good up to date sim, but they do require a faster computer. A up to date 2GHz Pentium or AMD processor, 1 GB of Ram and a good Open GL Video card like the NVidia 5600, ATI 9600 or better is what you will need. Obviously there are a LOT better cards out there than those now, but I would say they are the minimum. You can get Aerofly Pro Deluxe or G3 for around $200. It will save you an incredible amount of time in learning and $1000's of dollars in crashes.

The secret to 3D is have a plane that is designed to fly 3D. There are tons of 3D airplane choice out there now in several different styles and sizes, just depends on what you want.

The Space Walker is not one of them though.. Its just not built for purpose.. Its too heavy, the control surfaces are too small and its too stable and its probably under powered.

You need a plane like an Extra, Edge, Yak, Katana, Sukhoi. Or what would be even better to start is a 3D funfly type planelike a U CAN DO, Sig Mayhem or a Profile 3D plane. A Little more advanced would be the Fliton Inspire, Funtana, Showtime, the new GP Reactor (cool plane though), those are planes with a thin wing that 3D great but they are really slippery and you have to be a little more advanced to fly 3D with them.. The Profiles also fly great and are tough as nails.. Companies like OMP, Swanys (MOJO series) and a few others make some GREAT 3D profile planes.

What you do not want for 3D is a Space Walker, 4 Star, any trainer, Cub (but I have seen it done), Somethin Extra', those sorts of planes are not really made for 3D.
