I had this problem with my Prophecy when trying to land. I thought killing the engine helped... but it was because I was forced to land then. This airplane would gain speed fast anytime you put the nose down. So I dirtyed it up a bit by using elevator to flap mix (spoliers in effect). Ailerons went up when I pulled up on the elevator. This made the airplane land like a *****cat. I one time made the mistake of killing the engine when I had the mix on and nearly dumped it about 40 yrds out. Airbrakes. spoilers, what ever you want to call it, it works.. The spoiler effect makes the nose come up exposing more of the wing area creating the needed drag to slow the plane down. I literaly went from 5-6 pt landings, including some -0-'s to 9 and 10's because of the increased control while still having the engine running.
It will probably vary from plane to plane, trans to trans on the setup up but I used about 15% mix on ailerons to the elevator input. You can grease em in with the power up a touch and have the best rudder control and best of all it gives you that nose high landing that the rule book calls for.
