ok..thanks for all the info.and help.. i did not mean to yell.i allways do caps,they look cool..i forgot and, did not think to add in the lift of the airfoil. im using 6 deg.neg incidence on stab. this design is flying in a wegde or a bind.. not to effective..tons of drag!!..i have been told that the a-10 is very pitch sensative..i can see how...the cg and C/L are a mile apart..
