Completed final alignment of pitch horns and drilled pilots for two AN3 bolts in each. Also marked lower strap for 5.5 degree point. Removed blades for drilling and trimming of strap. Will have to reattach and remark for 7.25 degrees of tilt. Also recieved new sealed 24AGX Concorde battery to replace the 35 battery with caps. Now now leakage issue!
