mark you made and cut off the excess wire 1/4" [6mm]
beyond the bend. Enlarge the outer hole of the throttle servo
arm using a 5/64" [2mm] drill bit. Connect the pushrod to the

BRUSHLESS MOTOR INSTALLATION

Mount the Motor

The installation of a brand of out-runner brushless motor
other than the Great Planes RimFire 63-62-250kV should
be similar to the procedure listed below for the Great Planes
model. Be sure to maintain the correct prop adapter distance
from the fi rewall regardless of which motor you choose to
install. A template is provided on page 51 for installing the
Great Planes Extra Large Brushless Motor mount.
❏
1. Cut the template out on page 51 for mounting the Great
Planes Extra Large Brushless Mount. Use tape or spray
adhesive to hold the template to the fi rewall. Align the vertical
and horizontal lines on the template with the embossed lines
on the fi rewall.
❏
2. Use a large T-pin or a wire sharpened on the end to
transfer each bolt hole mark on the template into the fi rewall.
❏
3. Use a 7/32" [5.6mm] bit to drill holes at the four marks
you made on the fi rewall. To reduce tear-out, make pilot holes
with a smaller bit fi rst, then fi nish the holes with the 7/32"
[5.6mm] bit. Insert a 8-32 blind nut into the back of each hole.
Use a 8-32 x 1" [25mm] SHCS and a few #8 fl at washers to
draw the blind nuts tight against the back of the fi rewall.
❏
4. Attach the motor to the brushless motor mount using
four 3mm x 8mm machine screws, four 3mm fl at washers,
and threadlocking compound. You may need to remove the
brass collar to fi t the motor to the mount. Be sure and replace
the collar after the motor is installed. If you haven't done so
already, install the prop adapter to the front of the motor using
the hardware included with the motor and threadlocking
compound.
