I know a lot of guyssayyou can balance them right side up and they actually will do it that way.Which is ok. Go with what works for you.

I just found from my personal experience Ihad better results doing them upside down.I still do the finger test as a last resort, double check.Just to see if there was any kind ofa difference. On a couple of planes I did right side upwhen doing the double check test somethingdid not seem right. So I did them again upside down and the double check test was good. Again that is something that is not really necessary to do but it is something Ido to just double check me. Guess it lets me sleep better at nght.
Good luck.....
