Motor for the Gearbox
Step 1
The shaft of the Motor has a D-shaped tip. It needs to fit into this D-shaped hole of the center Cog C in the Gearbox.
It may be necessary to rotate this center Cog C to match up to the current position of the Motor shaft. Do not try to turn the Motor shaft itself. If necessary, use the D-shaped end of the supplied Turbine Shaft to rotate either Cog C on the sides until the center Cog C is correctly aligned:
Fit the shaft of the Motor into the Gearbox (and center Cog C) as shown, noting the orientation of the flat sides of the Motor and the wires.
This Motor needs to be fully seated, with the brass gear cage level with the sides of the Gearbox, as shown:
Step 2
Feed the plug of the Motor wiring out through this square opening of the Motor Housing as shown:
Slide the Motor Housing up the wires to the back of the Gearbox, enclosing the Motor:
When you are sure the wiring is not pinched or trapped in any way, secure the Motor Housing to the Gearbox with four (4) AP screws:
Step 3
Feed the plug of the Motor wiring through this square opening of the Base as shown:
Slide the Base up the wires to the bottom of the Motor Housing, as shown:
Secure the Base to the Motor Housing and Gearbox with four (4) AP screws:
Step 4
Slide the D-shaped end of the Turbine Shaft through the slot in the Base and firmly into Cog D of the Gearbox, as shown:
Thoughts
I am hoping this tiny Motor can drive both engines, the shafts, and all the propellers. Based on the reduction gears inside the brass cage, I think it will create a good amount of torque. We should find out in the next issue!
