The resolution of forces is such that the plane flies horizontally, even though it is not oriented horizontally.<br /><br />Brenda, in my forties, I spent a good deal of time building model airplanes from kits of balsa wood and tissue paper, wielding an exacto knife. I am afraid they did not really fly [somehow I always managed to mke them nose heavy], but they looked pretty good.Robert Paul Wolffhttps://www.blogger.com/profile/11970360952872431856noreply@blogger.comtag:blogger.com,1999:blog-5687347459208158501.post-34168065858646366432010-04-03T14:23:58.623-04:002010-04-03T14:23:58.623-04:00I've seen it done many times, both real and mo...I've seen it done many times, both real and model planes. My sons and grandsons probably could give you a clear explanation but since I tune them out about such things I can't answer the question. Model plane and helicopter building and flying has been epidemic in this household since our older son could manage a glue tube. He did a demo on Zoom in the early '70's on the kitchen table and nearby grass. My contribution has been to say UhHuh at intervals.Unknownhttps://www.blogger.com/profile/02636727394832760278noreply@blogger.comtag:blogger.com,1999:blog-5687347459208158501.post-38360134275535544102010-04-03T12:27:57.947-04:002010-04-03T12:27:57.947-04:00(This may be the single most stupid thing I have e...(This may be the single most stupid thing I have ever said but....)<br />Tilting the nose of the plane up to combat downforce then it`s not perfectly horizontal is it?NotHobbeshttps://www.blogger.com/profile/09443644930695303411noreply@blogger.com
