I agree with the basic 'high performance' AC landing techniques mentioned earlier, but will add a couple things.  First off, 45 degrees of flaps is overkill, you're getting alot of drag, putting yourself on the back of the power curve, and changing your cg for the worse (landing wise).  I plan on limiting mine to around 35 degrees, but havn't tested that yet.  Anyway, 'good approaches make good landings'.  Set up for a good 'power on' approach at a safe speed ( over 100 mph).  On short final, slowly start to bleed off power, and maintain trim.  It should be a smooth gradual reduction of power all the way to touchdown.  If done properly the plane will be 'ready' to land about the time of roundout. But there's nothing wrong with leveling off over the runway (1/8" ha), and slowly reducing power till touchdown.  May be obvious, but hope it helps someone.
