It's either the Cap or the Sukhoi. They have the larger elevator surface then the other models. They performer 3d tricks alittle better. Besides that all the planes are just about the same. The wings are the same. It's like they are all the same plane as fare as wing span weight and all the other stuff. All they did was make them look a little different. I found the same thing with their new line of 30 ARF'S. they to are the same plane they just changed the the fuse and tail section alittle and cowl. the wings are the same the landing gear is the same so on and so on... When you get to the 60 size there is alittle bit more of a difference but they still use the same wing and air foil. the fuse is almost the same on all as fare as construction. The 3 new 60 ARF'S suhkoi, giles, edge are different from the older ones. even those three new each share some of the same features with each other. The nice thing about those 3 are they have air foiled tail surfaces.
