Balancing a Propeller

Horizontal Balancing

A. Align the propeller’s blade horizontally along the balancer shaft.

If the propeller blade falls out of horizontal alignment:

• Carefullyusesandpapertoremoveasmallamountofplasticfromthe

entirefrontoftheheavierpropellerblade(inthedarker-coloredareas

marked“A”and“B”ontheaboveillustratedpropeller).

  -Use80-gritsandpapertoremovelargeamountsofmaterial.

 -Useanersandpaper(150-gritorner)toremovesmallamounts

ofmaterialforasmoothernish.

• Usecleartapeorpainttoaddmaterial,ifyoudesiretoavoidsanding

the horizontal position.

Vertical Balancing

A.Alignthepropeller’sbladeverticallyalongthebalancershaft.

 (Thisisoftencalled“balancingthehub”.)

If the propeller blade falls out of vertical alignment:

• Carefullyusesandpapertoremoveasmallamountofplasticfromthe

frontoftheheavierpropellerblade(intheareasmarked“A“or“B”on

• Removeplasticfromthebladeuntilthepropellerstaysproperlyaligned

intheverticalposition.

Final Balancing

A.Afterverticalandhorizontalbalancing,turnthepropellertootheranglesalongthebalancershaft.

If the propeller blades fall from an angle:

• Carefullyusesandpapertoremoveasmallamountofplasticfromthefrontoftheheavierpropellerblade(intheareasmarked“A”or“B”ontheillustrated
