Welcome !
First of all you should know that 3D flying is highly addictive ! You will also soon become the crazy and dangerous flyer at your club. The Warbird and parkflyer crowd will point you out at the club meetings and complain of your flying style. You will also going to try to hover every plane you fly (even the ones that are not supposed to hover)!
OK, now to your question : Get the video from Jason Shulman ! It will explain and show you how to get into the 3D flying. Very nicely done !
