I've seen several pilots at our club have great success with the new Hobbico Sensei trainer:

The Sensei is available with or without a radio system, so you can use your existing radio or get one included with the plane. We've had two new pilots solo very quickly on their Sensei trainers, and they both still enjoy flying them even though they've added more challenging aircraft to their hangars. Another pilot, a gentleman who seems to have a terrible time keeping any other trainer up and flying successfully, bought a Sensei a couple of months ago. He's been flying it regularly and it still looks like brand new.
There are plenty of good electric trainer aircraft out there. I sure wouldn't try to talk anyone out of purchasing a Radian glider or an Apprentice 15e. I've just seen a number of recent successes with Sensei owners. Having flown them myself, I think the Sensei makes a really good aileron trainer. I also like the fact that you can pick your own brand of radio equipment if you'd like.
