Some Nitro Planes stuff is unbelievably good and some is garbage. Like RCKen says, forget about decent instructions and be prepared to figure things out yourself and possibly make modifications.
For $10 more you can get the Tower Trainer which is known to be good, has great instructions and is backed by top-notch support. Keep your eye on the Tower Hobbies home page and you may just see a discount coupon from time to time as well.
