This conversation could get heated quickly... BUT since it seems to be coming up more and more often I wanted to offer my personal experience.
My hobby funds have never been expendable. I have always had to sell one part to buy a new one. Over the years I have gotten very lucky and not been burned too much by the more budget friendly components. I have purchased several sets of used electronics as well.
As my flight skills progressed I started noticing odd tendencies and behaviors I couldn't tune out. On the advice of a friend, I tried a "better" tail servo and instantly my problem was gone. Does that mean my tail servo was garbage? No, it did the job just fine for where I was then. But where I am now, it can't keep up. So here I am 2 years after building my beloved N7, I am buying a new tail servo.
Someone very recently told me something that struck a cord. " Buy cheap buy twice, buy quality buy once "
There are many brands of servos/ESCs/Motors/FBL etc to choose from and they all have their place. The brands that have a superior product will charge more, but if you only have to buy it once, isn't it worth it in the long run?
I am sure your Align servos will do the job, they have been working thus far and you should have no lack of faith in them. But when is the last time you heard MKS having a bad batch, or Futaba, or Outrage?
I have made the personal decision to go all Futaba or MKS. Both have proven reputations in the industry. Yes some MKS take an extra shim on the cyclics of the current Synergy models, but that's a 5 cent fix.
