The old timer that I fly with ran across a rare find today.....an original, complete ,unbuilt Top Flite Taurus. He is an old pattern flyer from the 60's and 70's, so he is familiar with this kit. He asked me to post a question here, since he has no use whatsoever for a computer. He read that the plane has a 70" wingspan, but calls for a 40 size engine. He wants to go with a bigger engine...say a 60 2-stroke or a 91 4-stroke. He realizes that this is a pretty rare kit, and doesen't want to butcher it ....so he wanted me to ask if any of you guys have/had this plane, and what engine you used in it. Also, he is considering taking the plans and having a kit cut, and keeping the original just as it is. Any thoughts?
