Propeller Installation

Prop installation on the IF1200A platform.

PreviousProp HoldersNextSafety Collar Landing Gear Installation

Last updated 4 months ago

Be aware that incorrect propeller installation will flip the aircraft over if you're attempting to launch. Be very careful to install the correct propeller on the correct motor. Each motor has directional CW ">>" or CCW "<<" markings on their side. All propeller tips will be facing down, never up. Remember to insert the locating pins. Use a dab of medium strength Loctite on each screw. Tighten to the screws to 1.2nM of force. Remember: the leading edge of the propellers will always be in the same direction as the motor's directional markings.

Prop Versions - Rev A and Rev B

There are now two versions of the IF1200A props. Rev A and Rev B designs. The original props (Rev A) use four SHCS M3x6mm screws. The new design (Rev B) uses four SHCS M3x8mm screws.

~ Rev A screws should NEVER be used on Rev B Props.

~ Rev B props CAN be installed & used with Rev A props on the same aircraft.

~ Do NOT disassemble or remove the prop blades themselves from the central hub on either Rev A or Rev B designs.

Propeller Orientation

Reference the following image (Fig. 1) for the standard propeller locations:

Clockwise (CW) propellers attach to motors #1, #3, and #6 (Fig. 2)

Counter Clockwise (CCW) propellers attach to motors #2, #4, and #5 (Fig. 4)

Clockwise (CW) Under-Mounted Propeller Installation

STEP
ACTION

1

Install the small diameter side of the locating pin into the opening on the top of the hub of the CW propeller

2

Place the large diameter side of the locating pin into the opening of the motor

3

Align the propeller hub with the screw holes on motor #1, secure the propeller to the motor using (4) SHCS M3x6mm

  • Ensure propeller is flush with the motor

  • Using torque screwdriver, torque these to screws in a crisscross pattern (seen below and labeled in Fig. 2) to 1.2 Nm

4

Repeat steps 1-3 for motor #3 and motor #6

5

Ensure propellers are installed in the correct orientation as shown below (Fig. 3)

CW Propeller Alignment

Counter Clockwise (CCW) Top-Mounted Propeller Installation

STEPS
ACTION

1

Install the small diameter side of the locating pin into the opening on the bottom of the hub of the CCW propeller

2

Place the large diameter side of the locating pin into the opening of the motor

3

Align the propeller hub with the screw holes on motor #2, secure the propeller to the motor using (4) SHCS M3x6mm

  • Ensure propeller is flush with the motor

  • Using torque screwdriver, torque these to screws in a crisscross pattern (seen below) to 1.2 Nm

4

Repeat steps 1-3 for motor #4 and motor #5

5

Ensure propellers are installed in the correct orientation as shown below (Fig. 5)
