Great choices, and good luck. My trainer is the H9 Alpha, and I am having great luck with it. The engine has given me no trouble at all.

In addition to being easy to build, the other great thing about the 4* is that there are tons of very good build threads with very detailed pictures of every step. Take your time and read a couple of these from start to finish before you even open your box, and you will have a really good idea of where any potential mixups might be. There really aren't many.

This is one of the best threads, with some excellent pictures:
