e-E-Flite Blade CP CX 400-3D > Main Blade Balancing

Got a question is it a good idea to check the balance of the main blades. Im assuming that unbalanced main blades can have a pretty good effect on vibration, even if they're just a little bit unbalanced. Any thoughts, thanks.

They are so light - I haven't messed with it. I haven't even weighed a pair to see how close they are. Been having too much fun to take that much time ;-)

I have not noticed any vibration - I am on my 3rd set of blades.

Maybe if I had a real slick/accurate balancer - like a Koll Rotor Pro - I'd go for it.

In general though - yes it is critical to check the main rotor blade balance, and spanwise and chordwise CG. The heavier the blade - the more important it is.

i just measure the cg of the blades and if i get any vibration prior getting it into the air, i put tape on the cg points. If wrong blade, vibration worse. Right blade, vibration goes away. Not very accurate, but better than nothing
