Number Crunching
Interesting replies. Doug Reeves, are you paying attention? Smells like a business opportunity; use the VAF website to solicite and sell the data.
Let's do metrics! See what that produces while I wait for others to respond.
Root among the Van's numbers on time to build, and you get 1,600-1,800 hours for a standard prepunched kit, QB's ~ 1/2 the time or 800-900. The QB price delta is $8K, which yields 9-10 $/hr. Four years ago I asked Ken how much time the QB might save on the -7; he opined 4-500 hours, and didn't think it was a good deal: 18-20 $/hr.
Personal validity test: it took me 1,200 hours to rivet the metal together, and another 1,200 hours for engine/firewall forward, systems, and plastics of various types. Painting added yet another 150 hours. I have $75K into it. Having built one, I'm sure I can knock out another in Van's time of 1,800 hrs and achieving the level of assembly the QB represents would be about 700 hrs.
So? 8,000/700 = 11.43 $/hr, the remaining 1,100 hours at the same rate is ~ $12,600, for a total labor "cost" of $20,600. Could I sell my ship for 75 capital plus 20K labor = $95K? I doubt it. It is a nice IFR ship, told me by those who have nothing to gain from stroking my ego, but I can't take my ego to the bank.
So let's have some more actuals!
