Suspect DS8411
Guys,
I need a bit of advice on a servo.
I dug out an old DS8411 that was involved in an accident last year. When I put a servo arm on and try to move it by hand it is rock solid! But when I apply power it works just the same as a 'known' servicable servo. Same end points, speed and singing when under load, I can't see any difference. I'll never trust it on a major surface again, but if it's safe to assign it to nose steering or something else then great.
Does anyone have experience of this?
Thanks in advance for any help.
Chris

RE: Suspect DS8411
you must read again your post.
do you think you aford to louse your stering servo or you think is less importan?...
,,,,i think you are the one from all of as here who know better your servo history.
so open it up check the gears and try with vibrations to make it not to work...
bottom end its your call.good luck
....in case you dont want it ill have it!

yup, I've had the cover off and checked out the gears, all appears well. The servo was new when it went in the last model. Try as I might, I cannot get it to produce a fault.

Try it out on a cheap high wing trainer.....preferably first on "non-important" controls and if you are happy move it around....that way you will be testing it out under vibration conditions.

If in doubt throw it out.
I would never use a 8411 on stearing there is toooo much play around the center, In fact I have sold all my 8411 for that reason.
The servo is fine for flaps or other functions that do not require precision around the center.

Well, it will never fly in a jet again, I have a few old prop jobs that it can go in - a new one it is!
Thanks for all the input.

The motor has gone "live" that is why it is solid without power, I've seen this before, it would need a new motor fitting, so with 8411's so cheap keep the case and gears etc as a spare. It will die totally if you keep using it.
