Fixed pitch tail rotor


The e-motor for the tail rotor got attached to the rear tail boom bracket with two bolts. Wires got soldered to the e-motor, feeding through the tube forward to the power distribution box. Which is not yet finalized. But this box will take power from the main rotor battery and divert it back to the tail rotor as needed. The tail rotor is a fixed pitch design and its rpm can be controlled independently from the main rotor rpm.

Nervous


Getting ready to put the order in for the LiPo batteries. After confirming the size, weight, and capacity, I think I will be fine with 336 batteries. I will order 360 anyway, just in case. Plus changing the BOM will require so much effort. I'm an engineer not a paper-shuffler. Also got some drawings for the leading edge, spar, and trailing edge. End plates are necessary too. Plus 9 bolts to fix the end plates to the structural profiles. Stuff starts to come together.
