HS65mg vs HS5065mg identification

[nameci]

Is there anyway to tell which is which? I got a used heli with servos that look like Hitec HS-65MG or HS-5065MG except all three labels are missing from the case. What would be a good way to identify which servos I have? I just don't want to take a risk of hooking them up to 3GX w/o knowing it is for sure HS-5065MG...

Any difference in the internal/board that I should be looking for? Externally, they look identical(I have another sets of 65mg and 5065mg I'm comparing). Ones with no labels have a small circular label on the side of the housing w/ green leaf icon.

1. The green leaf means RoHS compliant = the product is environmentally friendly.

2. Neither servo handy tonight but from the files..
. Digital Servo - Digital (aka FET) Servo & difference with Analogue Servo (PDF).
(This is a Futaba publication, extract attached hereto - all servo differ somewhat but principles remain same)
Also attached are photos of boards from two burnt out HS-65MG servo which should be good for a comparison with the boards on each of your servo.
(Attach a horn so as to hold top, pins & gears in place, remove screws and lift base plate to expose board.)
