CAUTION: In the next step we will be running the fan
to full power, so proceed with great care and wear
hearing protection and eye protection.
❏
5. Once you have confi rmed that the motor is running
in the correct direction, put on your hearing protection and
safety glasses. Advise anybody else in the area to do the
same (or ask them to leave the area).
❏
6. Firmly holding the fan duct in your hand, point the
intake away from anything that could get sucked into it and
point the exhaust in an area where nothing will get blown
off the workbench or blown around the room. Checking your
surroundings, advance the throttle to about 1/3 stick. If the
motor and fan run smoothly hold the throttle in this position for
one minute. Continue the test-running procedure as described
step 10. If you detect any unusual noise or vibration cut the
throttle, disconnect the battery and turn off the transmitter.
❏
7. With the power disconnected, remove the top of the fan
duct and inspect the fan and housing for any signs of rubbing
or wear. If necessary, remove the fan and use a hobby knife
to remove any plastic that may have been deposited on the
fan blades or in the housing. If you can’t pull the fan off with
your fi ngers, you can make a “fan puller” from 1/16" [1.6mm]
pushrod wire as shown.
❏
8. Remount the fan 180° from the way it was, then reinstall
the nut with threadlocker. Run the motor as described in step 6
to see if the problem has been solved. If there is still vibration
or rubbing, remove the fan again. This time also remove the
adapter shaft from the motor—this will also require removal
of the motor from the fan housing. (Or you could drill a 3/32"
[2.4mm] hole through the housing 5/8" [16mm] back from the
front edge. Then, you can insert your hex key wrench down
through the hole instead of removing the motor.)
❏
9. Reinstall the adapter shaft onto the motor 180-degrees
from the original position and remount the fan with the nut.
Once more run up the motor to 1/3-throttle.
❏
10. Once you can get the motor and fan to run smoothly
at 1/3-throttle for one full minute, advance the throttle to 2/3
stick and run for another minute, then fi nally to full power for
30 seconds.
❏
11. After you have confi rmed smooth operation of the
motor and fan unit all the way to full-throttle, disconnect the
battery, ESC and receiver. Use a few drops of CA or canopy
glue to tack glue one of the foam fan cones to the fan.
❏
12. Guide the motor wires down through the hole in the
wing and attach the fan duct to the top of the wing with the
magnets.
❏
13. Secure the fan duct to the wing with the nylon bolt.
