34.You will have to bow the cover plate to close or
pry with finger to remove the cover plate. Note
the opening is forward to the nose for battery
cooling.
35.Make sure the shaft has a little bit of free play
when you pull and push. If it is too tight then
loosen the nut for more space.
36.Next install the propeller and spinner, always
take great care on the motor and swinging
propeller as it is dangerous and may cause
serious injury, if you are a beginner we
recommend you read the manual of radio and
speed controller thoroughly to understand how to

the geared 370 motor comes with super powerful
magnets. Never rotate the propeller improperly
as it may hurt the gears.
