Most of us early builders have come to the conclusion, that had they been available, we would have done them: 1.empenage/ tailcone, 2. wings, 3. fuselage, 4. finish kit, 5. avionics, 6. firewall forward. Actually, there are several items that I would do in a different order, but I would have to have, at least, the first 4 kits avaiable to do that. Hope that helps. Steve
