Anyone have experience with a UCD and Tower .75? Will it hover?

Before you laugh, I was shocked by the recent Model Airplane News article comparing the Tower .61 with all the others, including the .61FX. The Tower has way more torquge and hp, I don't have the numbers in front of me.

Horesepower per cubic inch shows the Tower .75 should equal a .91FX (all else being equal, which it's not).

Any thoughts?
