Sig SE or Global Ultimate
What a BEAUTIFUL job, Cuban8. That's a gorgeous model.
I agree with the statement that the Somethin' Extra does many things, but none of them well. It's a great little knock-around model; but I sold mine after putting a lot of stick time on a pal's Contender. The Contender is just as agile as the SE, and more stable in "normal" flying. Plus, that central flap gives it all sorts of neat capabilities. All that comes at a price; it is a PITA to build. The SE almost builds itself; I'm just finishing up the wing on my new Contender, and it really is 70s-vintage construction...
But of course, you can't get a Contender ARF. If the Tower Kaos ARF is half as good as the kit version, THAT is what you want for pattern-type flying. The Kaos is one of those classics that I will always have one of. I've got a 40 that I built 7 years ago; found the kit at a swap shop- it had been packed in 1975! It is my old stand-by, replacing one I foolishly sold 10 years ago. The only thing I've done that flies better is a Kaos 60. I lost that one years ago, but was given another kit (1974 vintage) by a friend who ran across it at a swap shop in Ohio. That one I'm guarding like gold. I've been hesitant to build it, because I know there probably aren't any more, period.
The Kaos is certainly not a fun-fly type. But you won't find anything in a sport model that flies more smoothly.
