"Very impressive, well written and illustrated instructions. The build is very innovative, pistons worked perfectly, hinged rear fork for placing the rear tire. There is very little repetition of steps, always fresh. Build is very solid and no popping off of parts as you handle it. I like the sculpted smooth parts. I was in no rush to finish, just savor the moments, so I didn't track my time. Take the time to I.D. each part for placement and you will be fine. I would like to see better color definition and color separation of parts in the manual, old eyes and color blindness you know. Overall, one of my top favorite builds."
