The first pack of parts centered on the battery box constitutes the base plate of the entire helicopter. The linkage mechanism between the front landing gear and the two main landing gears needs to be squared off with a few yellow cross shafts, properly assembled as shown in the figure.
The second package is mainly used to build the cockpit and joystick and rotor linkage mechanism, a variety of linkage construction is quite clever, many designs in the official LEGO kits are quite rare. However, a large part of these structures are not completely fixed in the assembly process, but also to the subsequent steps to leave a false position, to a few steps later and then combined, the first time to start will inevitably be a little uncomfortable.
The complex gearing and transmission makes the third package much more difficult. A slight distraction of various gears of different sizes and colors will cause the linkage to stall, so be sure to carefully check the gear linkage and gear switching in a timely manner against the manual when assembling.
The fourth package made up the remainder of the rear fuselage as well as the separate tail brace. The yellow on the tail is not the classic yellow I expected for an engineering vehicle, but instead has some fluorescent yellow to it.
After the fifth package was made into the white canopy and the back of the head on top of the fuselage, the H-175 helicopter was completed.
Finished product quick view.
