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.

Tail boom assembly


It was about time to think through and start the tail boom assembly. Picture one explains it all but let me walk you through. So the big tube will be equipped with two brackets. One in the rear to hold the tail rotor e-motor to the tail section, and one bracket in the front that will hold the whole tail section assembly to the fuselage (office chair). Some bending, drilling, and welding is involved. All these single parts are aluminum, by the way. The tail rotor will be powered by a small e-motor, specs to be released later. It will be a fixed pitch propeller, which is not finalized yet. Picture two shows the night shift I pulled to get the welding done. In picture three, the tail boom gets bolted onto the fuselage. Picture four shows that work is done for today. Good night...
