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 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.

RE: Whats the difference between surface and air servos?
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.
