Servo Cleaning

Apr 08, 2010 2 Replies

Does anyone else maintain their servos, or am I just weird*?



I just finished cleaning the pots in a couple of servos in my little much-crashed World Models AT-6. They work great. It's been in the repair shop for about two years now**, but if I can get the engine started it'll be back in the air soon.



So I'll have something that can fly upside down, without strings!


  • Granted, they're Heathkit servos that I built myself (about 30 years ago, egad!), so it's not like there are any direct replacements _or_ like I can't do the work.


** After a serious crash that broke the nose mostly off (thank goodness for CA glue). It happened about 30 seconds after I put the plane down on the grass, thought "gee my allergies are bad, I shouldn't be flying today", and took off anyway.


Most people don't do it, but they should. Taking care of them would make them last longer and you find problems before it causes a crash.

True. Although I will say, reversing HS-55 servos is a severe challenge to one's manual dexterity and ability to focus on small objects.
