Rather loud and there is a lot of head walk in the spline. I was able to shift it back and forth with just my nail. But movement seems smooth.

I'd like to recommend to check gears before use. I have more than 10 servors of this type and in few if them I found small fragments of something. After cleaning and re-lubrication it looks reliable

I put four of these Servos in a brand new SkyWalker V6 and one of them burned while maiden flight. They where powered at 5 Volts. Now I have to buy another SkyWalker :-(

Gear stripped easy on one of mine, suggest the metal gear version of this one is better. HK-15178B Digital MG

Cheap. When crashes are likely they are a good way to keep the repair costs down. There are better digital servos but not for this price.

Excellent servos. Very little backlash, accurate travel and good centring. Well worth the money.

Ok.
I do animatronics as a hobby and as such I tend to look for a lot of inexpensive servos.
I decided to try these seeing as they were advertised digital (and I have found a few that say digital but are not)
These unit are very good for the price. They really ARE digital (you can try that by putting them on a tester and then stressing them a little - the buzz that you feel is the number of times it is trying to reset it position. These sing - not buzz so the update frequency is more than 20ms which makes them a digital)
They hold very well - even to the point of breaking the horn rather than shifting. The alloy shell is also excellent for dissipating heat if you are running them continiously.
So for the general hobbiest these are a great buy. I'm also going to look at the others in this range too.
