YES!

Your Avistar taught you the basics, but it also didn't teach you about flying sport planes, especially planes with tapered wings that WILL tipstall if you land or fly them too slowly like you Avi does. I'm speaking from experience. I flew for years, then bought a 3D/pattern plane and about crapped myself the first flight. IT was SO different and had what I thought to be very bad flying tendencies. After some time I now have come to love the flying characteristics, but at first it was a handful. If you think buying one plane then getting another is expensive, it's still much cheaper than buying that Edge, then totalling it on the maiden flight, then buying another...
