After crashing my first Ultimate that was from a kit I went out and bought the ARF version. The ARF goes together fairly quick with a few little improvements along the way, but overall if I munch this one I would not hesitate to buy another. I took care of a weak area in the way the top wing is bolted down which was easy to do and the ailerons were actually about 1/16" too long. That was just cosmetic and no one has really noticed. I fly mine with a YS .91 and had to mount the rudder servo behind the rear cockpit former and installed 2 elevator servos under the stab. These changes were made for more direct control and also helped with balancing the model.
Also, the plane is covered in 1 solid color so you'll need to trim it out with another color or two but overall, of all the planes I have this Ultimate is the one I seem to take out more than any other. As long as you put it together straight and give it enough power you'll love it!
