Hi chaps
I know this subject line is old news to some and most will probably know the
answer (including me) but I have to be absolutely sure of my facts before I
take a hacksaw to this piece of 4130 tube in my hands.Mark L, I think I
raised this subject with you some time ago, please bear with me here. So
here goes. I am using the AS5048/5045 combination . I know these airfoils
were designed to be a direct replacement for the RAF48 but I am not sure if
the CG limits are the same. I am particularly interested in the rear limit
at this stage.I know that the CG limits are particular to a specific airfoil
and not the plane itself (I think). I have to be sure that the mains will be
behind the rear limit, by how much I will still have to figure out.
I have been given conflicting information locally (Rear limit: from 6mm to
12.6mm behind the rear face of spar with the spar centred on 25% chord.
Help!!
