I will 2nd misslemans post by saying a twist 40. Its my 2nd plane after training on a mustang pts. It is a really fun plane to fly. It lands softer than a trainer. With a mild head wind, you can almost set it down like a heli. It would make a good entry level 3d type plane. Its not a speed demon though. Too much speed can lead to the covering coming off. Ive read several posts in the twist thread with this issue. I was advised, and would recommend the same to anyone using a twist as a 2nd plane, to fly on low rates until you get used to it. It will roll at an insane rate. Even on low rates. Its a fairly inexpensive plane to build but it can be a bit fragile. Its built light for the acrobatics.
This is my new plane of choice when I go to the field. It gets flown twice as much as my trainer, but I still have fun with the mustang.
