Mike:

I agree with Shaz, a foamy or EDF F-18 will never be the same as a turbine f-18, I was shocked about your comment between the 18' and the 16' but then I realized you where speaking about EDF/Foamy models. The F-16 is problably the easiest airframe to fly (except for the Fly Eagle Jet F-16) the 18' on the other hand, is a handful. If you are OK with Semi-scale try to find a Cermark Turbine F-16, so easy to fly it's unbelievable, very slow landings, and no it is not ridiculously fast on the recommended set-ups, but can be with a big enough turbine...

Other F-16 airframe options are the Tamjets F-16, the Skymaster 1/8 F-16 and the Jetlegend 1/8 F-16, the Tamjets and the Jetlegend come from basically the same mould as the Cermark and they share the same flying characteristics, the Skymaster, I do not know about how it flies.

You mentioned the F-15, I understand it's also very easy to fly and land, but will be heavier and require a larger engine.
