I don't think that unless you can fly well on the simulator you should try to fly any trainer on your own. Unless you have a huge huge field that you can keep flying straight forever, I would recommend you to get something like a park flyer.

Actually the airplane I would recommend a first time flyer is the Multiplex EasyStar because it really is a friendly plane to fly and it's very safe because it's foam and a pusher. You can see the video on hobby lobby. The guy literally puts the TX down to throw the EasyStar and doesn't pick if up for a while as it flies away. This is a good beginners tool.

Another way to practice before you get flying is to invest in a cheap remote control car. Of course, a plane is not the same as a car but the orientation is important as well as the ability to proportion your input and compensate for over input. I don't mean get a car and crash it all over the place. But set up a track from cups or something and try to get that car through it without touching the cups. Remember, you can't follow it. You must stay in one position preferably a distance away. This excercise will help you with one of the most difficult things in flying, plane orientation. Furthermore, it'll give you a better idea of throttle control. Rather than on or off, as most beginners do, throttle control is very important to good flying. In fact you should be able to fly your trainer with just rudder and throttle as long as you have dialed the plane up for level flying at half throttle (glow only... beginner RTF electrics will generally need 3/4 throttle to stay level at a speed safely beyond stall speed).

After this exercise, you should be able to fly your EasyStar. Just remember, give yourself time to react. If you jam the stick any which way and when it's going the wrong way you can't save it, you'll lose the plane. If you give yourself time by not turning too fast, going up to fast or anything too fast, then you can fly "slower". Most importantly, as soon as you can turn, try to gain altitude... 3 mistakes high is best place to start doing more advanced things. Lastly, if you ever lose control, let go of the sticks. A trainer and the EasyStar will fly straighten itself out all on its own.

If you do not heed my advice and go for another glow trainer, make sure you try to negotiate for a volume discount. :-)

Drive as far as it takes to get to a club that can give you a few lessons maybe even buddy box you. In fact, just having someone trim your airplane out on its maiden flight would be invaluable!
