Motor Mounting screw sizes.
11 series motors use M2.5 screws for the motor case.
14 series use M3 screws for the motor case.
15 series use M3 for the the 1515 and smaller sizes and M4 for the 1521 and larger.
17 series use M3 screws for the motor case.
19 series use M3 for the motor case.
19 H series use M4 screws for the motor case.
22 series use M4 screws for the motor case
The Maxon gear box uses M2.5 screws
The P32 uses M3 screws.
The P42 and F3A gear box use M4 screws
The P62 gear box uses M5 screws.
Make sure that you use a quality screw that is the right length! Too long of screw can damage the windings and too short a screw can pull the threads out of the housing. Both of these problems are not warranty issues! We suggest that all screws have Locktite 242 or similar to keep the screws from backing out.
How to avoid costly repairs.
Make sure that you mount the motor using the right length screws. Screws that are too long can contact the windings and cause damage.
Make sure that your prop or rotor are balanced. Vibration from a unbalanced load can damage the bearings and motor windings.
On geared applications check the lash to avoid bearing problems.
Help protect the motor leads from vibration damage by using zip ties to secure the wires that exit the motor and attach to the speed controller. Secure the wires from movement relative to the motor housing.
To avoid over heating the motor check current draw and see that it is with in the suggested range for your motor type and model.
Number of poles?
The 11,14,15 and 2200/12 series motors all have 12 slot stators and 4 pole rotors.
The 12 series motors have 24 slot stators and 26 magnet poles.
The 2200/24, 19 and 17 series motors all have 24 slot stators and 8 pole rotors.
The 44 series motors are 36 slot stators and 12 pole magnet rotors.
Suggested controller settings when using the CC125 and CC180 controller with NeuMotors FAI type motors:
Set cutoff to 4 volts (option 2)
Disable current limit (option 5)
Brake type: Hard brake, no delay (option 4)
Throttle type: Fixed throttle (option 2)
Advance: Low advance timing (option 3)
Cutoff Type: Soft cutoff (option 2)
Soft Start: Fast start (option 3)
PWM Switching Rate: 13 kHz (option 1)
Note that that Castle has released an improved version of the software, which lets the user adjust the brake ramp, which is a good idea as the
brake is very strong, and has been known to break motor mounts. You need to use the link to install this option. See the Castle Creations web
site for information http://www.castlecreations.com.
Settings for ICE and ICE HV controllers when for F5B use:
Use software version 4.01 or higher!

Helicopter settings for the Castle Creations HV series controllers settings:
1) Cutoff voltage --depends on number of cells
2) Cutoff type--Soft cutoff
3) Throttle type-- Heli: Governor high for most 19 series applications and high RPM 15 series setups.
4) Motor start power-- Custom: “0”
5) Throttle response-- Custom: “0”
6) Motor timing-- Mild advance
7) PWM--13khz
8) Current limit--Insensitive
9) Governor gain: High (80)
10) Spool-up speed-- Custom: 10
General Castle Creation ESC settings for all Neumotors:
1) LVC—settings depend on your setup and number of cells.
2) Current limit disabled for high F5B power setups—up to user for other applications.
3) Brake—depends on user needs. Sport planes usually have brake off. The newer versions of software offer user selectable braking for larger F3A and IMAC stunt planes.
4) Throttle type—fixed.
5) For most uses the low advance setting is best—motors have better efficiency. “Y” wind motors can use medium advance for a little more power or speed. “D” wind motors should always use low advance as there is no improvement with higher advance settings.
6) Cutoff—up to user.
7) Startup—depends on use. Sport planes the soft start is good. For contest planes the fast start is best.
8) PWM frequency –the lowest settings work well with all Neumotors 11/13KHz.
Settings for “other” brushless ESCs:
1) 11XX,15XX and 22XX series of motors are all 4 pole designs. 19XX series are 8 poles and the 44XX series are 12 poles.
2) Use low (0-10 degrees)or medium(10-15 degrees) advance settings for “Y” wind motors and low (0-10 degrees) advance settings for “D” wind versions.
3) Brake settings are up to the user and application.
