Checking the Main Blade Balance The stock wooden blades,were out of balance,although their CG positions were the same.I bolted the rotor blades together,while they were positioned on a piece of glass. This was just to make sure that their leading edges,were inline with each other. I turned up an aluminium rod on my lathe and drilled and tapped a M3X0,5 thread into the one end. The rotor blades were then attatched to this rod and then placed onto a DuBro prop balancer. Immediately,I could see which one was the heavier blade. Tape was added to the lighter blade and it works very well. I fitted the blades onto the Titan and there is no vibration issues at all. The attatched photos,show a pair of carbon blades and they need no balancing. Regards Craig
