RC Ken spent a lot of time developing the list of trainers listed by RTF, ARF, and kits in his sticky post, one of the very first ones in the Beginners Forum. Spend a little time in there and see what may meet your needs, go to the web site listed and take a look and see what you want to get. Generally speaking, though, the larger the airframe (within reason) the better the trainer will be because it will be both a tad slower than the smaller ones, and very visible. The RTF's all come with all that you need to fly that plane minus the field support stuff.. starter, fuel, tools, spare glow plug, and so on.

I have flown several trainers. I've flown the Tower 40, the NexSTAR Select, and the Hobbico Super Star. All fly great and are great trainers. The largest of the three is the NexSTAR Select, which is what I solo'ed with. My most recent purchase is the Hobbico Super Star. I bought it as a club trainer. I removed the OS LA 40 angine and put an OS 46 on board which really sparked it up a bit. It performs as a great trainer. I also have a buddy box to support new flyers without equipment. The reason I did this was so that any new-be's that are not sure if they want to do RC can come to our field, fly the trainer on an buddy box with a qualified instructor, and see if it's what they want to do without having to spend a lot of money on new equipment only to find that they don't like the hobby.

Good luck with anything you choose to fly.
