I've been doing some reading up on edf's and found now where saying how to balance the fans. Is there an easy way or is a learn from you mistakes type of thing.

Any help in this would be great

If you look at the Test Flying section of my [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=1031]E-flite F-15 Eagle[/link] review, you will see one way to balance rotors. Using a good balancer like the Dubro Tru-Spin Prop Balancer, you simply sand the blade tips until the rotor no longer favors the blade. You can also dab a small amount of clear nail polish (or spray paint) on the opposite side to add some weight.

Good luck!

Thanks for that so what your saying is that it would be just like balancing and prop or a set of heli blades then right

Correct.
