Hi,
Just to throw my ideas into the ring.
If a model is taken from a classic design and turned into a 3D plane this isnt a bad thing. The reason is both precision pilots and 3D pilots can get alot out of it. Just because its 3D capable dosn't mean you have to give 50 degrees on everything!!
Just watch the TOC..3D machines performing precise graceful manouevres. Then if you want to dabble in 3D all you need to do is hit the D/R switch and possibly move the CoG.
BTW i'm currently turning a zen 50 into a 3D machine
Have fun
