I think the term you are looking for is Reynolds number and you are right, bigger flies better. He did say in his second post that money is an issue but than again he said that he made up his mind to get an EF Yak because of the flight characteristics yet except for the prototype the plane does not exist so how does he know?

I think this is just another thread comparing IMAC planes and we are advising someone who doesn't have any experiance. Based on that I still stand by my recommendations in the other thread similar to this one.
