Well, I suppose I will be the only one saying I perfer the 2.3. I am not a IMAC competatior, and I have a Brison 4.2 instead of the DA. The 2.6 is bigger and presents better in the air but I find the planes fly almost idenicial but because of the expense and the ease of transportation I like the 2.3. The 2.6 with the DA has much more verticial, but the Brison does well also. I sold the 2.6 before it was built, but I have since flown it and either way you go, you will be a winner!
