I noticed recently that one of my Align 610 servos had become very stiff to move by hand unpowered. It felt like the grease had solidified and become very thick. If I move it back and forth by hand very fast several times it will free up. I thought I had cleared some gunk and would clean it out later. When I came back it was stiff again. When I took it apart the oil on the gears was actually very thin. I could see that the gears were moving freely and that it was the motor that was stiff.

Can I clean or have the motor serviced or is it shot?

It has been running on a 6V LiFe pack. It is two years old and only has about 50 flights on it. It is exposed to nitro exhaust which I would wipe off at the end of the day. There was some nitro oil inside but it wasn't dripping wet. I noticed Align doesn't put rubber seals on the servo case like futaba does but I didn't think the inside was that bad. If I do need to replace it it is obviously going back to the same spot and will be exposed to the same exhaust. If that is what caused this I will need to find some way to seal it but I have never heard of this being necessary.

This is a different servo than the one in my other post with the bent pins. The gears and pins in this one are in perfect shape.

Don't know the servo but I find brushed motors start to get hard to turn when they start going south. Maybe the commutator where the brushes ride is getting a little rough.

I'd replace it. If it were the motor to a small plank, I'd say run it till it won't.

You can keep some slime out by taping around the servo case seam. I don't think slime had anything to do with your motor dying though.

I don't know exactly what is going on but I think I will just replace it. $60 servo now or a $300 crash later.

I would like to find out if exhaust exposure was a factor though. When the new one goes in I don't want it to fail in 50 flights again. I think most designs have a servo or two exposed to exhaust though don't they? I have never heard of anyone taking any special measures to seal their servos.

Yea, it doesn't sound good. I'd toss it, no need to wait for it to fail.

Having the same issue. Guess I'm buying a new set of cyclic servos.

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.
