Well i have had this jet kit for about 2 months, but just started building it a week ago. All togethor, i would say that i have 4 days of sheer building and it is ready to go. I learned from the trials of my first one, which i sold. It definetly sped up the process. However, Tam has a great product here. The instructions and components are top notch, and the plane is definetly a dream to fly. Heres the pix. Will hopefully maiden it this weekend if i can get a new battery pack by then. (my old one must have a bad cell). Nick
