Well I am going to go out on a limb here and suggest something else. Awhile back i got into SPAD building. If you are not familiar it is a offshoot from normal Foam and Balsa construction using cheap common materials such as PVC and coroplast (corugated Plastic). These planes are almost indestructible and when learning #D you are going to need it. One plane in particular is the best 3D trainer I could reccomend. It is called a SPA3DT. It is very simple to build and wil withstand an unbelievable amount of crashes. Here is the Link to the free plans:

Now I want to stress this is not a beginner plane but will teach you the basics of 3D better than any plane on the market and can survive all the dirt naps you can throw at it. No it is not pretty but, this is what I reccomend. Here is a pic. If you are interested head on over to the SPAD forum here at RC Universe or go to the SPAD home page at www.spadtothebone.com. Here is a pic of the one from the website. Also I attached the one page plans to build it. You can build one from scratch in a weekend one you get all the materials.
