I built my 4 star 60 within a week working about 3 hours a night, this plane was so easy to build that I actually enjoyed building the kit. SOme mods you can do is remove one bay per wing, this helps the plane roll and sanp quicker. The covering job will take you a little longer, it took me about 3 weeks on and off working about 3 hours a night. My color scheme was not easy so it took some time.
