2.4 Prop Mounting
NOTE
: Here is some terminology we’ll use in this section.
The “front” is the direction the pilot faces while flying, the “rear” is the opposite direction.
The “front” of the prop can be identified by the thick side of the prop blades.
The “rear” side of the prop can be identified by the thin side of the prop blades as the upper blade
section shown in fig. 9.
The “rear prop flange” is the one that is most rearward when the prop is mounted.
The “front prop flange” is the one that is mounted on the reduction drive.
The red arrow in image, indicates the direction of propeller rotation.

Mounting the prop is quick and easy.
Place the rear prop flange on the rear side of the prop.
Insert the four (4) prop bolts through the rear prop flange and prop.
Place the black rubber friction washer over the prop bolts on the front side of the prop as shown in Fig. 16.
Now mate the prop/rear flange/bolt assembly to the front prop flange that is on the reduction drive.
Place nylon-insert lock nuts on the bolts, and tighten them evenly.
The correct torque to use is 50-inch lbs. MAX. A more practical “field method” of torquing is to tighten the
bolts snuggly and evenly, but not enough to begin to crush the wood of the prop.
