My two cents ....I would stick with glow and get her introduced to an instructor at a club in your area. Have her Join AMA. then look at getting her own plane, I have a strong feeling in pride and ownership. Help her with the basics on the ground, and let someone who is qualified to teach do so. I have been working with my 11 year old daughter who is new to flying as well. We are building her a goldberg eagle that will be her airplane. I am sure that I could teach her to fly, but I am going to leave it up to an instructor at the club. Congrats on finding a G/F that is into flying, she sounds like a keeper.
