Servo problem
 

Hi Guys, I changed the connectors on my old Cox servos for a Futaba receiver and while one works great, one does not. The one in question is a Cox/Sanwa 80412. It seems to make a lot more noise than the other and sometimes "lags" while going one direction. Does anyone have any advice on this or know what to look for before I go tearing this thing apart? Is it possible that it may just need some lubing from sitting around inactive for so long? Thanks! Prop

That sounds normal for Sanwa servos!:D

Seriously, I'm using two 80111's and they are very slow and noisy. I keep meaning to replace them, but I can never get a round to it.

Well, I took the top cover off and after inspecting the gears for damage, noting nothing was wrong except they were a little dry, I took some of the white grease that was inside the cover and spread it around the gears with a toothpick. After reassembly, it still had the same problems. I took the bottom cover off and removed the motor. it was squealing when I let it run wide open. A drop of light oil on the shaft fixed that and also the lagging and noise problem! It now works nice and smooth, although like Dave said, a little slow.
