Empty CG = 175,730 / 1,643 = 106.96 in aft of datum.
The empty weight reflects N720AK’s actual configuration as of 2025-11-18.
The Monkworkz MZ-30 generator and BOSCH relay (~2.6 lb total) were installed
2026-03-09, and the Borla regulator replaced the Aeromotive 2026-03-17. These
changes are minor (~3 lb net) but the airplane has not been re-weighed since.
Re-weigh at the next condition inspection or major mod.
