Thanks, I think I am gonna try the bubble levels tomorrow, the blades are pretty good balanced, actually i didn't have to put any tape, it's the 2nd set of blades out of 7 that I have got and doesn't need to be balanced. However, I'll check the balance tomorrow again. I don't know much about blade tracking, actually so far, that is my main problem![&o] , I understood that I am better to check it at 65% that is the hover pitch.... right?????? does that mean that eventhough it starts bad (at around 40%) and it gets on track at 50% or more.... is it ok?????? or it should be at ALL % of throttle well tracked from 0% to 100%?????????

About the bubble levels... can I use double-face tape to stick the bubble level to the blade? and then at 50% throttle, both blades should be bubble leveled... right????? and at any point of the throttle the bubble level in both should be the same..... is it that???? Thanks.
