Gentlemen,

My Great Planes, PT40 flies with a tail down attitude. The balance has been checked and if anything, the model is slightly nose heavy. The experienced flyers in the club have advised me not to fly this model as it wallows and is hard to control. The engine is an OS 46 LA that can be leaned out to about 11,000 RPM. In a nutshell the model appears tail heavy and equipped with an engine with NO power; the prop is 10X6. It appears like the after part of the airplane doesn't want to fly. Any suggestions?
