What equipment are you running in it? And how much you asking for it?
Stitz those light dual a123 1100 packs might be your problem why you need the nose weight along with the über light muffler. I am using two 2600 A123's from EP Buddy and I have a J-Tec Pitts on my DA-60 and balance came out perfect. All I had to do was slide the 123's around till it was right.
I must say this is my favorite airplane to date! Haven't stopped flying it since I put it together. Just an all around excellent aircraft.
I flew an 89 slick for three seasons but never felt as comfortable as I did with the Extra even on its maiden flight. Photos from my flying buddy Tim.
