When most new flyers first get on the sticks of a 40 size trainer, they tend to over control the plane and think that its too sensitive! After they get used to it they realize that they just neede to get used to the stick movements. Then they pass their solo and move on to a low wing sport plane. Now you are back to over controlling the plane again and think that the plane is too sensitive again! Also the speed is much higher which means that things can get out of control rather quickly! If you are lucky and don't crash the plane right away it only takes a few flights to get used to the quick stick reponse. Once you do though, over sensitive becomes a relative term. You go back to a trainer and it seems that something is wrong because you can't turn around on a dime! Bottom line, if the quick response of the plane you are flying makes it hard for you to handle then do not attempt to fly the Shoestring!!! Get more stick time on what you have until you can fly it as easily as your Telemaster. I would also consider an in between plane that will tends to land faster than the Stick but is also forgiving. . land Once the Shoestring is in the air, you do have to land eventually and then its too late to find out that you can't land planes that come ing in fast! Get used to a 2nd plane and then try the Shoestring. Then you may stand a chance!! [8D]
