If you're new to 3-D, its probably a good place to start. For me .40 size tends to be a bit too "zippy", evrything happens a a faster rate & wind can make them harder to 3-D. Thats why I like the .60 size U Can Do, its pretty big, but cheap. Its does things fairly slow so you can keep up with it, the rolling harriers are slow motion with standard servos, give you plenty time to adjust timing & get low. Its a good hoverer, recovers & flys out of stuff at near stall speed, so recovery is a plus. Its a good 3-D trainer I guess, just not a pattern or IMAC for sure. If you dont mind building, sounds like a Mojo would be a good start too, if you already have covering & glue & building supplies, a Mojo would get you there pretty cheap. Just get started!
