Pulled a late shift to get some stuff done while I can. You never know how busy the times ahead will be. After gluing the last batteries in place and feeding the wires through to the end, I let the glue dry over night. Then assembled to the blades to the head and bolted the close-out plates on. Three bolts each suffice. The rotor head is fixed to the e-motor shaft, which is a tailor-rolled sandwich tube for optimal torsion stiffness. The sandwich material enables feeding the positive and negative sides of the battery down to the e-motor. Connection established. Finally, big step! Got the main rotor onto the e-motor shaft. Now I'm tired...
