freefl2,

Nice looking bird! My last SE had the same set up you have (Saito 72 with tall TNT gear) and I had my CG at 4" behind the leading edge - and I think I even moved it back further than that but forgot to check it before I sold the plane. My new SE, I am starting between 4.25 and 4.5 but haven't flown it yet. I my first SE flew great at 4+?.

This one is an ARF
