RE: First 3D type plane
Some sound advice here so far. As you are learning 3D manuevers, you really need to push yourself and put it in the ground now and again throughout the learning curve. I am afraid with a big 30% 3D plane, you may be too timid to attempt the low to the ground manuevers. Rightfully so, way too much invested in the big boys to nose in pulling out of a inverted flat spin or falling out of a hover.
That being said the U-Can-Do, Twist, and mojo are great suggestions. If you are stuck on a bigger plane, my Funatana 100x is a blast with a Saito 1.25.
