 3. Connect the ESC to the motor and secure it
to the inside of the fuselage using hook and
loop material. Actual ESC location may vary.
 4. Slide the propeller adapter onto the motor. Place
the propeller onto the adapter, then a spinner
cone onto the adapter and secure.
Note: It is very important that you check to be
sure the propeller is balanced before installing
onto the shaft. An unbalanced propeller will
cause performance issues. E-flite™ propellers
will need the center hole drilled out to fit the
shaft size of your outrunner. It is very important
the hole is drilled concentric.
