Only one answer I can think of. 4*s get a 40 size if your transportation is a big problem. If you have a little bit more room, go for the "60" size. They're super easy to build & an absolute joy to fly. There is all kinds of threads on the 4*s to help you build & possibly "bash" a little. I've had 2 of them & (had) ya dumb thumbs. I miss flying them. They make a good pilot better & a bad pilot look good !!!
