The first is that you can always use a little more power. And the second is that there's a DLE engine to deliver it.

The DLE-55 generates 2.2-4.4 pounds of static thrust than the original DLE-50.

That means you'll have the throttle response you need at any time and attitude...and the power you need to nail any maneuver you want to fly.
