Brief Description: Connect Aft Nav and Strobe light/Tail Boom Ground
|
|
Connect Aft Nav and Strobe light / Tail Boom Grounds / Cabin Blower Indicator Light / Vertical Stabilizer Holes / Spin Tail Rotor Heim Joints / Connect Tail Rotor Cable
I also have been completing the stand-offs and bundling on the exterior of the helicopter as I go. Only the interior wires are still loose and in need of organization. I ran only sync and power wires to the fixtures, and will handle the grounds at the light themselves.
For the ground connections on the tail, I used a special wire brush bit that has a built in guide nub in the middle of the bit to hold it in place inside the hole you are removing the paint from for a grounding point. Using a cordless drill, the result is a completely round grounding point that you can cover with a washer, bolt, or nut to complete the ground. I did this on a bolt back at the tail rotor, at the mid boom beacon, and at the main connection of the tail and cabin frame. This completes the grounding connections for the entire frame of the helicopter from the nose to tail.
I next completed the wiring of the mid-boom beacon and the aft navigation light. It was really fun to have those connected to the rest of the exterior lights and strobe lighting the hell out of the dark shop.
I next moved back to the connections for the tail rotor cable. The final adjustments will be taking care of with the rest of the final rigging, but for now I adjusted the tail rotor at almost a zero pitch as it relates to the normal torque of the engine, and allowed the majority of the pitch to counter the engine torque. This will allow the engine to turn the ship, and the tail rotor to stop and counter the torque produced. I assembled the final joint connections, but without the cotter pins because I know I will be adjusting them further. With the engine torque in mind, I also need to consider having proper left and right control during auto rotation. If I don’t allow for enough negative tail rotor pitch, I won’t be able to control the ship in that direction without the engin
