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.
