Well, I *did* say to sync them up, didn't I?
Yes, he wants to adjust them so they're as close as he can get them, but for sport flying, eyeballing it ought to be more than accurate enough.
... yup, thought I did.
If the two halves match at zero and at the stick's extremes, they're probably just fine. You certainly don't need some gadget to mount in the plane to match them up for you (though a throw deflection meter might be nice for use on the ground.) Just use identical servos and do it by eye. If you find that you can't make them match up (because they're just plain different) try some other servos.

If they appear to be matched to your eye, and your new guy still can't stay upright, then the problem is probably somewhere other than the two elevator servos. Perhaps your eye is defective. :)
Now, if you're doing precision pattern flying, and you're good enough that differences too small to see cause problems, then you'll probably also know what you need to do to fix that. Certainly, I'm not that good :)
