Mount The Electric Motor; Mount The Motor Battery - GREAT PLANES EXTRA 330S Instruction Manual

Mount the Electric Motor

❏
1. If you haven't yet done so, mount the prop adapter to
the electric motor using threadlocker on the threads.
❏
2. Separate the front and back halves of the ElectriFly
motor mount. If necessary, remove the collar from the motor
shaft with a 2mm hex wrench. Mount the motor to the mount
with four 3 x 8mm or 3 x 10mm SHCS and 3mm fl at washers
and threadlocker. Replace the collar with threadlocker on the
set screws.
❏
3. Mount the back half of the motor mount to the fi rewall
with four 8-32 x 1/2" [13mm] SHCS with threadlocker and #8
fl at washers. Join the front mount with the motor on it to the
back of the mount on the fi rewall so the propeller adapter will
be 6-3/4" [170mm] from the fi rewall. For the 63-62-250kV
RimFire motor, the screws that hold the halves of the inner
mount together should be in the third-from-the-front and
third-from-the-back holes.
❏
4. Glue together the plywood parts for whichever ESC
mounting platform that best fi ts your ESC. There are two
mounting platforms included–one is wider than the other.
Mount your ESC to the platform with whatever method is
intended for your ESC–Velcro and a rubber band for the
narrower platform or mounting screws for the wider platform.
Securely glue the mounting platform into position as shown
and connect the ESC to the motor. (As you can see, the
ESC will be directly in line with the air scoop in the cowl, thus
receiving a fl ow of cooling air.)

Mount the Motor Battery

IMPORTANT: Before experimenting with different battery
combinations and connecting multiple battery packs with
adapter plugs, refer to the "Battery Precautions/Connecting
Batteries" on page 33.
❏
1. Bevel the front edges of the plywood battery mounting
plate to match the angle on the front of the engine box under the
fi rewall. This side will now be the bottom of the mounting plate.
