First of all. You are awsome! When I was 14 I did not want to have anything to do with my sister. She was a year and a half older than me and and flew in different social circles. I think it's great you want to help involve your sister in your activities. So again, OUTSTANDING. For $30 your not going to get much but I will have to admit I have had some fun with the Air Hogs line of planes available from Wal-Mart or Toys 'r Us and they are near your price range. Problem with them are that the slightest winds make them unflyable and they are rather disposable in that they will simply use up the usable battery life or electric motor life in a short time with regular use. But it may be enough to get her hooked If she is anything like my 13 year old daughter she will soon meet boys so don't be disapointed if she gets side tracked. I have a beautiful Great Planes Cub with a brushless and Lipo set up that is getting very dusty because of this.
