Chaz,
depending on what pinion you use in your trex 450SE, you might find the Venture to be easier to bog the head. 30 sized helis are on the low end of the power scale. But they're awesome in that they don't use as much fuel and if you manage your collective/cyclic well they can do a suprising amount of moves. And the tability/size of the heli will be a real plus.
