Paul,
I have a fun fly that I burn holes in the sky with. I have a Sunray (RCM plans) that I go fast with. I also have a few scale planes that I fly in a scale like manner - Cessna 182, Flivver, Ryan STA, Lancair ES. My thoughts are that you should fly the plane for what it was designed. In some very early messages after I posted some info on my first Lancair, someone asked me "if it would snap roll". I was somewhat perturbed by the inquiry as I thought, if you want a plane to do aerobatics why not buy one that was designed for that (Extra 300 or something like that). I know that GP advertises that the Lancair will do some aerobatics but why put it through the extra stress?

Don't get me going on the topic of how one should fly a scale plane - it is simple - fly it like the full scale!!
