Default RE: engine and prop

Do you know your idle numbers?
Have you had landed the plane with the engine off?
Is there a difference?
Some new light airframes are difficult to bring them down because of the thrust of the props. You may want to try a bigger prop with less pitch but your plane will fly different than the way it flies by now so you must consider that option.
As Minnflyer mentioned, try to change the CG a bit, if that does not make any difference on landings, then check your idle numbers, and if your engine cannot idle on the lower 2,000 rpm then think on lowering the pitch of the prop, enlarging the diameter.
