IMHO. I have a Twist with a Saito 72 and on low rates it's very docile but still fairly fast on landing with no wind. On high rates it's more fun but it's still not a true 3D plane. On mid rates, it's a nice sport plane.

I also fly a Magic 46 3D ARF and it's lighter, much more of a second plane type of aircraft. The Twist does better in the wind but the Magic is slower and gives you more time to think.

Your mileage may differ but I hope this helps. As was said earlier, a second plane is different for everyone. I flew an Aerostar 40 for 2 years before I got up enough courage to try anything else. My second plane was a Magic type design and it did more to improve my flying skills than any other plane.
