The Weasel is a breeze to build. It took me about 4 hours. I think I could have shaved a good hour off that but I used UltraCote (Oracover) to cover it. The tape method is faster although I much prefer the finish of the Ultracote. If you have built a foam wing in the past this plane will present no problems. If this is your first EPP plane then the instructions are some of the best I have seen. You can preview the plans on the flyweasel.com websit
