[MOC] 42113 D Model — Erickson S-64 Aircrane

[Ngoc Nguyen]

 

Erickson S-64 Aircrane is a unique heavy lift helicopter and is one of the 10 biggest heavy lift helicopters in the world. The original version was designed by Sikorsky under the name Sikorsky CH-54 Tarhe. It was used in Vietnam to transport and to retrieve downed-aircraft. The Boeing Chinook might be a cool heavy lift helicopter, but this one is a cooler heavy lift helicopter that lifts the Chinook.

 

 

Due to budget cuts, the CH-54 stopped being upgraded and the whole program was cancelled. It was retired in the 1980s, and the heavy lift function is carried out by the Chinook instead.

The Sikorsky S-64 Skycrane is the civilian of the aircraft. Erickson bought the type certificate in 1992 and has been manufacturing as well as operating them since then under the name Erickson S-64 Aircrane. The most common civilian uses nowadays for this aircraft is firefighting and power line transportation.

My model comes in two versions, similar to previous alternate models: Motorized and Manual.

The motorized model has a power unit attachment that contains the motor and the battery box and is shaped like a container.

 

 

 

 

The manual version has a triangular water tank with two valves in the bottom that can be opened to simulate water dropping.

 

 

 

Other details include the rear-facing cockpit with its own pilot seat to handle the load or the fire fighting and the steps on the two legs as well as on the starboard side of the aircraft.

 

 

 

The model is slight out of proportion because:

- I have to use the 3x11 panels to ensure the structural integrity. According to right proportion, the side walls should be 2 studs tall only.
- The tail should be longer, but I made it short so that the flex doesn't bend the axle that rotates the rear rotor.
