squeaking ball links??

[Terryscustom]

I did this on my 42% MXS scratch build. I built the plane to pound on with 3D flying so I had hinges every 4" on the aileron.....all glued in with poly glue. I used some plain old old 3-in one oil and put a super fine CA glue tip on the bottle to get the smallest drop possible. Oiled every hinge and it went away but usually came back after a while. I've had others others done with poly glue do the same thing though.

Ok, thank you!! I am convinced!! When I get home from the super bowl party, I will lube the hinges!! Thanks again!!!

In previous years, I have used Byron Lube Booster for Nitro fuel and Q-tips when installing hinges. Works great especially on Robart Pin Points. Never had a hinge that wasn't wisper quiet. Recently though, I have been using Engine Builder assembly lube. Great stuff.

Dip a toothpick into the oil and you will get just enough on the end of the toothpick to put on the hinge.

Just take a pair of pliers and gently squeeze the link on top and bottom of the black housing and that will free it. This is caused from over tightening during installation.

I posted this question in February, and after 200 flights and over 40 hours of flight time, I determined the source. It was not the ball links, and it was not the hinge points. It was one single servo on the right wing. It would squeak anytime i did a 2 point roll or a 2 of 4. I could hear the squeak from 400 yards away!!! LOL!!! It actually sounded cool.
But, all kidding aside, the squeaking came from a JR MP 82T servo, and not from the gears. I opened up the servo, and there was no wear, no slop, no bearing problems. The actual problem is the core less motor. When i spin it, it makes the squeak sound.

Here is a video of the squeak:

i will post pictures soon of the servo inside.

Quite the followup. I was wondering where this was going. Good to see you found the source.

Maybe a dry motor bearing? I used to get that same sound from worn out motors in my slot cars.

has to be! the squeaking was recreated by turning the motor only.
