“In this stage, you fit the middle chassis frame to the middle chassis, as well as assembling the propeller shaft.”




Materials: The Middle Chassis Frame is metal, but the rest of the parts in this stage are plastic.


Middle Chassis Frame & Propeller Shaft

Step 01

Retrieve your Chassis assembly from the previous stage and turn it upside down. Place the Middle Chassis Frame onto this location of the Middle Chassis and secure it into place with two (2) EM screws.

There are four posts on the Middle Chassis Frame that sit down into matching recesses of the Middle Chassis here. This is also your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Turn the entire assembly upright again and continue to secure the Middle Chassis Frame to the chassis with four (4) CM screws, as shown:

Step 02

Fit the Propeller Shaft Cover to the Propeller Shaft, aligning the screw holes, and secure it together with four (4) IP screws:

Step 03

Slide two posts of a Universal Joint between the tabs at the end of a Slip Yoke, align the holes, and secure together with two (2) IP screws.

These IP screws do not have to be fully tight; this allows a little movement in the U-joints:

Repeat this step to build a second Universal Joint/Slip Yoke assembly:

Slide the unused Universal Joint posts of one of these assemblies between the tabs on one end of the Propeller Shaft assembly, aligning the holes, and secure into place with two (2) IP screws:

Repeat this process at the other end of the Propeller Shaft assembly with the remaining Universal Joint/Slip Yoke assembly:


Those little U-Joints were tricky as there is nothing really to grab onto!
