Raj, It looks like the last one which was also from the newer line. I don't have the nose sections from the first two. The LG mounting block is pinned and the firewall has tristock on the vertical sides, other than that this is the one with the extra support on the fuse sides where the wing bolts on. Anybody know what the incidence is supposed to be on the wing? I want to meter these before I install the control surfaces. #3 just did not fly as well as 1+2 The wing didn't seem to seat right. Regardless of the CG it always had a nose up attitude. We will see on this one. Joe
