What size is the Cox 80412 servo?
I need to replace a rudder servo in a E-Z-Bee foam job.

Not exactly a direct answer, but while poking around I found this and bookmarked it as being potentially useful:

If you are replacing the servo, don't you have one to measure up? I have two 80111 Cox/Sanwa servos in my bits box - these appear to be mini size or so. I thought they came from a late '80's - early-'90's Cox E-Z Bee or something like that, but not sure anymore. If one of these will get you going I would be more than happy to put it in the mail to you.

i have an ez bee i replaced the servos with hitec 81s you could also use 55s

Hi MJD,
Do you still have those sanwa 80111 servos in your collection? If so, would you sell them?
Have a nice afternoon,
