1. Use the RimFire™ 1.60 motor mounting bolt
template to mark the bolt hole locations on your

fi rewall.

2. First, drill 1/16" [1.6mm] guide holes through the
fi rewall at the marks you made with the template.
Then, enlarge the guide holes with a 7/32" [5.5mm]
drill to accommodate the blind nuts.

3. Use a 9/64" hex wrench to draw the blind nuts
into the back of the fi rewall with one of the mount
bases and an 8-32 bolt. Optional: Apply thin or
medium CA around each blind nut to permanently
hold it into the back of the fi rewall—use care NOT
to get any CA into the threads.

4. Select the mount base/spacer/bolt combination
necessary to extend your motor the correct distance
from the fi reweall. Apply a few drops of threadlocker
to the threads on the end of the mounting bolts. Then,
mount your motor using #8 lock washers and #8 fl at
washers under the heads of the bolts.

5. Make certain your motor is secure and all the bolts
are tightened. Always use a balanced propeller.
