I just ordered the 66inch Extra. I have the Sukhoi and Edge, and they are excellent ARF's... I mounted my Saito .91's inverted on both... I'm going to mount a TT .91 inverted on the extra... Really nice looking models, and great flying machines... I like the extra wing loading they give you... you can slow these babies down without much worry of a tip stall (just don't push it).... The build is a little different, but I like to do some mods on all of my ARF's, so it was fun to build.... I don't like the little tail cone thing, but if you take your time, it will look pretty good... I'm not using flying wires on the tail, but I have gave it some thought...
