The number one cause of new aircraft loss and the number one mistake by the newbie arriving at the field the first time is 'CG to far aft'.
The number two reason is 'throws to high'.
And yes Phillybaby throws to low can also have first flight problems but since this is in context of the beginners forum and that beginner needs to have an experianced pilot do that first test flight anyway Its probably not prudent to susgest that a newbie use higher throws. Seen a lot of newbies and airplanes showup with throws far to high but have never seen one arrive with throws to low!
Just my opinion
