d.

 

Attach micro-switch mount assembly 
(note orientation) to motor mount plate. 

Check that pitch feedback rods are aligned 
concentrically with the three respective 
holes in the microswitch mount assembly. 
Insert the prop wires back into the 
microswitch mount. 

Thread-lock three screws (Loctite 243). 

Note:

 

If your propeller has the 
mircroswitch mount assembly using 
the microswitches with wires 
attached, then it must be upgraded to 
the style shown using PCB mounted 
microswitches.  Ask Airmaster for 
guidance. 

 

 

e.

 

Place the PC Brake Cover onto the motor. 
Ensure that the wires align with the slot. 
Push on until the cover seats on top of the 
motor. 

 

f.

 

Attach PC Motor Clamp to microswitch 
mount assembly with rivscrews. 

Note:

 

As an alternative use Pan Hd Screws 
8-32 UNC x 5/8”  (P0237) with 
primer 7471 and Loctite 277
