Balance Problems. I am using my HDX450 CF Blades for this Tutorial, but this video will apply to most Collective Pitch Blades like Align T-Rex ESKY Honey Bee CP2, King 2, Belt CP, Walkera, etc.
The way to balance any blade is "Matching the CG" and "Matching the weight". There are multiple ways to balance the blades and many tools.
You have to minimizes the amount of tape used and putting most of the tape near the bolt holes and the CG.
Another good tool is the "Heli-Max Blade Balancer" (HMXR4855 / $22.99), you can match the CG and weight with this tool. You can see the manual in pdf on helimax-rc site.
However I have used the Align "Blade Balancer" (K10289TA / 3mm bolt holes) for balance TREX 450 blades, it is only $4.99 and you can match weight property. I will post one video to show it.
Thanks
