I am a Newbie at RC Fixed Wing. I have just built a Spad Trainer an a friend has given me an OS 46 AX Engine for it. I would like to balance the propeller for it on a balancer I use to balance Helicopter blades. I have searched the site on information about balancing props but I need more information.

Question ---- How do you make the blades balance? ...... Add weight to the lighter side or remove material from the heavier side.
