Having built kits for 20 years...and my last one taking approx 30-40 hours to complete...and then getting into Spads 5 years ago...the scale Spads taking 6-8 hours to build (while designing at the same time and taking photos)...and the non-scale Spads taking 3-4 hours to design and build, and then the latest rail Spads taking about 2 hours to design and build. Hmmmm, go figure. Ace Bogie, How many years have you been in the hobby, and what is your building background?
