Well, I mic'ed the prop saver hub and found a drill bit that is about .002 bigger than the hub. I used a tap wrench to spin the drill bit by hand and open up the hole in the prop. It removed a single, thin curly of plastic in each flute of the bit and now the prop fits perfect on the prop saver. I used the prop tonight and it worked great. I do want to get a balancer but there is no noticeable shake or vibration. Problem solved apparently. Thanks again for all the help guys. Oh.....my son got some video of tonights flite. It's a bit boring in some spots so feel free to fast forward. http://youtu.be/GYcqL8y1bOg
That's awesome Wrench! Good to see you claim some airspace!
I've gotten lucky on some props -- whole batches that were perfectly balanced. More often than not a new prop can benefit from a small piece of tape on one blade or another . . . or sometimes a large piece of aluminum tape
(at least that's rare).
Go ahead and get a balancer when you can (and put it to good use), but In the mean time if the blades are whirring and not buzzing, you're probably be just fine.

I don't use a prop balancer. I just hold onto the nose of the plane tight, gun it up to full speed, and see how she feels. If it seems off, I add a small piece of tape to one side of the prop, if it got worse, then I remove the tape and add tape to the other side. But that's just me.
A lot of people use a burnt out electric motor clamped in a vice -- just pop out either the coils or the magnets, whichever's easier. Gotta burn up a motor for that, but it'll happen to us all, if we stick to the hobby long enough.
"Dynamic" balancing using the motor takes a few moments longer in trial and error (watch those fingers!), but it'll get you close enough for anything but a camera platform.
