MOTOR & ESC INSTALLATION

For this build-up we chose to install the Great Planes
28-26-1000 RimFire. We recommend this motor if you plan
on doing most of your fl ying outdoors.

❏

1. Remove the three screws holding the Y-mount to the

back of the motor and the two screws for the prop saver.
Apply threadlocking compound to the screw threads and
reinstall the screws.

❏

2. Test fi t your motor by holding it in place up against the

fi rewall. Make sure that the Y-mount screws fi t inside of the
clearance holes in the fi rewall. If it is necessary, carefully enlarge
the holes using a Dremel

tool or a sharp hobby knife.

❏

3. If you are installing the more powerful RimFire motor, apply

a bead of thick foam-safe CA to the fuselage-to-fi rewall joint.

❏

4. Install the motor using three 2.5 x 8mm self-tapping

screws. Remove the screws and the motor and harden the
screw holes with one drop of thin regular CA. Be careful not
to drip any regular CA onto the foam.

❏

5. Route the motor wires through the fi rewall and connect

them to the ESC. Use your radio to test the direction of motor
rotation. If the motor rotates in the wrong direction, swap the
position of any two of the three motor leads and re-check the
direction of rotation. It’s easier to do this now than to fi nd out
you have to swap the leads later after everything is mounted
and tucked away.
