DK, yes I do know this. That is why I prop my plane for max thrust not speed. The only time I go to anything like max throttle is on uplines. For over two years, I have been practicing throttle management and in IMAC contests I scored all 10's for sound. So these things you mention and talk about I agree 100%. I also know that many times what you will see as a left thrust problem is wind at altitude, unwanted rudder input with throttle input, or unbalanced control surfaces. I know all of this and that is why before I made the decision of adding any right thrust, I checked all of these. Nothing change. My only thought now after my experence with the PW Extra is to change from a Zinger 22x6-10 propeller to a 24x8 Airwild NX propeller or a MSC 24x8 propeller. I plan to order a couple today and they should be here next week.
Following experiments with the new propeller, I will make the decision on change the engine thrust.

Miles, you also have to realize, with a plane with a thrust to weight ratio, and a speed envelope, such as with this Edge, you will not have pefect tracking at all speeds and attitudes, you have to fly the rudder as well as all the other control surfaces. If you designed a plane for zero airspeed, i.e. hovering, waterfalls, and other "stationary 3D maneuvers" you would need max right thrust. Conversely, if you have a plane designed to go 200 mph all the time, you would need minimum right thrust. The Edge spends time in the air with a speed envelope from a little negative to plus around 60 mph probably, so you have to find a sweet medium for your right thrust, and use the rudder for the rest.
