How to Reduce Prop Vibrations

By Brian Christal, posted by Stephanie Pelczar 


Excessive vibration from an unbalanced or off-center propeller will lead to poor performance in flight modes that require accurate position calculations. The most important thing you can do to ensure that your propeller is not off-center is to use a prop ring adapter that matches the prop shaft on your motor.
Prop ring adapters are included with your APC propeller when you buy them through Tuffwing, or you may buy them through Tower Hobbies. (Part number LPAR06E.)


1. Install the 6 mm  adapter ring. Failure to use an adapter ring may cause your UAV Mapper to crash during your flight mission.


2. Remove the nut and washer from the propeller shaft.
3. Slide the propeller onto the shaft. Ensure that the numbers are facing toward the front of the
   airplane.
4. Hold the motor housing tight while you tighten the propeller nit. Failure to adequately tighten the
   nut will cause the propeller to spin freely.



Caution: Never arm your UAV Mapper with the propeller installed unless you are ready to fly. 
Always remove the propeller during any diagnostics. The motor may unexpectedly start if a fail safe condition occurs, such as no RC receiver. Only arm with propeller on if RC transmitter is on, throttle down, and Flight Mode set to FBW.
