Two steps to statically balance your R/C helicopter blades.
But now you might be thinking the blade you added tape to is going to be heavier than the other blade. Well, there is a simple way to check and make sure the blades weigh the same. Here are some of the tools that you will need:
1. Blade holder bolt2. Heavy duty string or ribbon: As for the heavy duty string, you can buy it at your local hardware store and the ribbon you easily get at your local gift shop.
3. Tracking tape or duct tape. You might already have the tools needed for this section from the Dynamic balance section. Okay then, let's get to the static balance...;
Step # SIX - To make sure the blades weigh the same, align both blades together at the root of the blades. Then insert the blade holder bolt screw and fasten the string or ribbon on the head of the bolt. Firmly tighten the bolt but not too tight, you don't want to damage the blades. After the blades are fastened extend the blades, make sure that the blades are parallel, like a straight line.

Let's continue to the next step...;
Step # SEVEN - Now, grab a hold of the string or ribbon and slowly raise the blades into the air (about 4 inches from the surface). Wait for a few seconds and take note on the blade that points up.
The blade that points up is called the light blade and the blade that points down is called the heavy blade. What you are trying to accomplish is to make both blades simulate a straight line. This will mean that both blades will weigh close to the same, and that's what we are looking for. So, on the blades that is pointing up (light blade), put tape EXACTLY on the C.G. point mark. The tape will add the needed weight to balance the light blade horizontally.
Technical Illustration:
You might have to play with the amount of tape you add to the light blade, because too much tape will make the blade to heavy and too little tape will continue to make your light blade the light blade. If you added the right amount of tape, your blades will stay at a horizontal position. If the blades are at a horizontal position, your blades are now balanced. Make sure to completely read this guide again before you install them on your RC helicopter, just to make sure that you have a full understanding of this guide.
Congratulations! By completing this guide, you have learned how to cost-effectively setup your RC helicopter blades.
You have specifically learned how to:
• Find the Center Of Gravity (C.G.) point.
• Balancing blades
• How to make sure you have your blades nearly weigh identically.
Please let me know what you thought about this guide, I'd love to hear from you.
See you at the field!
