I've always wondered where the mfg's come up with their estimates on completion time, because it takes me at least twice as long to finish an airplane as the mfg quotes...

For example, the GP Wagstaff.. I'm working on one and already have the quoted 15 hours in mine, and all I've completed is the gear, wing mount and tube, glued the stab, fixed the covering job, and hinged the surfaces with hinge points. Still have radio (6-10 hr), engine / cowl (4 hr), decals (1 hr), programming and balance (2 hr), and final rigging, and I'm sure this will be a 30+ hr job also...

I've built a lot of planes (75+).. Quickest was an avistar RTF for a friend that still took a couple of hours to a full scale homebuilt that took 700+ (advertised at 300).

I thought I was average and the the mfg claims were aggressive.. But maybe I'm just a slow builder (I enjoy it so I don't rush).... Are most guys really able to build in the advertised time???? Chuck
