I figured all the servos would be the same, but the servo on my heli's tail was totally different. When I took it apart I found that it has a different gearing configuration on the inside. It actually had the same main top gear as the digital D75 gears. So I am guessing that it is probably a digital servo while the others are analog...The tail servo has a different speed and torque to take care of the tail demands, so i am sure it would be a bad idea to use it. Maybe it is a fluke that my tail was set like this, maybe not, you will have to confirm that by looking inside the servo yourself...

Peace,
