Funny observation.
I could never fly reeds...and I had a hard time setting up a model with them. I let a reed pro fly mine and he said it was really flying good. He gave me the xmitter and I crashed while he was saying. "give it to me.""
I sold the stuff on the spot. Two weeks later, the pro was flying my model again and it was flying good...only he didn't offer to let me fly it.
As for "3-D"...I have a hard time not laughing when I see a model hanging on the prop. That is such a silly thing for a model to do.
It may be difficult but then it is a silly difficult thing to do.
