You're right, when you're all done it should stay no matter where you stop it but I believe you have to balance the tips first then the hub. The tips are done with the prop perfecty horizontal. The hub is done with the prop perfectly vertical. At least that's the way I always understood it. If this is wrong I'd like to know the correct way. I prefer to add a gram or so of glue rather than shaving off wood. Also I use little pieces of masking tape to balance it before adding glue. I like to see how far off it is.
What brand prop was that anyway? I bet the hole was not drilled in the center of the hub for it to be off that much.

thanks joeairport, the key is that prop should always stay where you stop it regardless of angle - bought a new one last week - it is hard to tell in hobbyshop which one is ok - I sanded off nearly 1/4 of hub to balance it - had to throw it away too dangerous. I am wondering if I should be adding weight rather than sanding it off? I have always sanded on back side of tips with flat sanding block then I apply thin ca using my finger w. a glove spread it around to re seal the wood - dries in 3 minutes ready to go. I always have to take off a little more wood to allow for weight of ca.
