Default Which is more efficient?

I am setting up a Taylorcraft 450, and tossing up between the 450 and 480 motor. Here is my question...

If I limit the travel of my throttle using the 480, so that it gives the similar performance of the 450, which will give longest flight time?? I just figured that with the lower resistance of the 480, that it might be more efficient.

You don't need to limit throttle travel on the Tx... that's what your left thumb is for. I'd say the 480 will do better, because it will allow you to use fewer amps to get the same result... it should spin a large prop more easily than the 450 can, so you'll need less throttle.
