thanks all for your help. i just centered the new wing....didnt use the old te or the old le.....so it overhangs both ends equally. i was planning on adding larger tail feathers.....just to be safe anyway.....although im not planning on making the fuse any longer. im hoping the cg will fall in the 25% range of the wider wing.....or fairly close enough to ballast it out. im going ahead with this thing....see what happens....[X(] only powered with a new OS .25. length of the fuse tip to firewall is 38". the new wing is 12" chord total flat bottom with a 2" thick airfoil.
