Whats the difference between surface and air servos?
 
I have some surface servos that I use in my airplanes. I was wondering what the difference was? I think I might have done the opposite in the past too, air servo in surface vehicles. I dont mean the torque value either.

I've used Airtronics 102 servos in the air and surface and never a problem. Some brands label for each use, but why I don't know. Waste of time.

I know that some servos are not recommended for helicopters above a certain size due to vibrations. Other than that you can use them interchangably as long as you have the speed and torque you want.

thats what I was wondering. i guess they just do that to make more money to folks that figure one is for only one type.

vibration issues is normally why servos has restrictions.

Some of the servo's I've seen marketed for surface application have an extra o-ring seal by the output shaft compared to thier aircraft equal. I'd assume this would be to help prevent dust/water etc from entering the servo, which typically isn't an issue with aircraft/helis. Other than the seal, I've never noticed a diff and have used them interchangeably as others have posted.
