I have decided to work on developing real 3D abilities. In line with that I have been looking at building a new 3D/IMAC plane. I have flight experience with all sizes of planes up to 85".

Here is my problem. I was going to build the new Wild Hare 28% Edge. I have one on order for January. I would have to take the DA50 out of my Mustang to go in the Edge. I don't want to buy another engine right now. Well low and behold I see that Goldberg is coming out with a beautiful 1.20 ARF Sukoi 26. I happen to have a brand new YS1.20SF engine sitting on the shelf. So what to do.

Question: From a flight standpoint, for those of you seriously into 3D, is there a significant difference between a 72" SU26 and the 84" Edge. Working on IMAC type flying would also be part of the equation.
