Title: How to balance rotor blades ? Post by: gauravag on April 07, 2010, 10:32:12 PM How do you usually balance your main rotor blades ?
Reason I am asking is that i had the covering on my Raptor 50's blades come off the edge a little bit, so I used some glue to stick that, and put a little bit of epoxy to seal off the open wood. It is just a little bit. However since its the tip of the blade, I am concerned it may cause vibration. Any ideas on how to balance this ? Title: Re: How to balance rotor blades ?

It is simpler to use a purpose built blade balancing stand.
I haven't done this much for myself, as I try to get factory balanced blades of trusted brands, and have not been crashing (knicking the blades) all that often recently. For the type of flying I like/do, I cannot take risks with unknown blade brands or any kind of damaged blades... that would be a fool hardy thing to do. Title: Re: How to balance rotor blades ?
