RE: radio question
Any radio that is comfortable in your hands and will fit your needs is all you need. Most of the computer radios now will hold multiple models.
I would suggest that if you are going to get help from an instructor, you should make sure that the radio you purchase is compatible with your instructor's radio.
New technologies are emerging, i.e. the Spectrum line. However, traditional radios will work well too. I personally fly with Futaba. I own a T6EXA, and a T4YF(buddy box for students). Again, a personal choice.
Suggestion, pick out a radio that you like, post the link, and then ask around if it will fit your needs. If you'd like, you can PM me and I will let you know what I think of your suggestion.
You don't necessarily need to get the most complicated radio on the market to learn to fly. Actually, I feel that the more basic, the better. That allows you to focus on your flying and less on playing with the radio.
Again, PM me if you'd like more personal information.
Thanks!
