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?
Well, I fly a PT-40. Goes beautifully, with an OS46LA as well. For what it's worth, I have an APC11x5 up front. Inverted, loops, stall turns, hammer-heads, everything you would expect from a trainer, and a lot more. The only time the plane feels "tail heavy" and "wallowy" is when inverted... which is no surprise for a flat-bottomed wing.
So, I can happily say that your plane is not behaving as it is supposed to, which means that it can be fixed... only I wish I knew how to do that.
