TF:
Sell the UCD and get a profile, It'll save you lots of $$$$$$ and frustration if trying real 3D is your thing.
Get a Slide 48 or a Primo 40. Unlike the Mojo 40 they have a longer tail moment.
Flying 3D is not about flying 3 mistakes high or hovering 30 feet up in the air, it's flying down on the deck.
Here's some vids for you:
