Surface Servos?
Hi guys,
Possibly dumb question: What makes a 'surface' servo unsuitable for air? For example, the Spektrum 6040? It's described as a surface servo, but the specs sound good for jet use. Why not?
TIA

Hi,
Thanks, Len. Nothing else, though? There's not like some little chip in there that senses altitude and then self-destructs the servo because it's supposed to stay on the ground?

A friend who used to work in a hobby shop said it refers to the length of the lead.
I bought a pair of 'surface' Futaba analog servos to drive flaps (high torque, reasonable price)
and the leads are shorter than what I would expect.
The instructions do warn about using 'ni-cd batteries only' perhaps because some people would
use dry cell batteries in their cars which could not provide the current to drive these servos properly
but I checked the current draw & it was nothing too outrageous.
