RE: Dave Patrick <span class=
I have a D.P. ultimate 40 I got it at my lhs in December 2002 it's the first and only one recived. It was my first bi-plane and first extrem airobatic plane and I love it. It's not to unstable and lands just a little hot. I have an O.S. SX 50 in it and it will do unlimmited virtical. I have an extra 300s form G.P also but the ultimate is still ma favroite.
