Hobbico CS-12MG Servo Hi-Speed Metal Gear Micro

Anyone tested these servos, Hobbico CS-12MG Servo Hi-Speed Metal Gear Micro U. For the price they sound too good to be true. Do miricles still happen?

It's a rebranded Hitec HS81MG. Not horrible, but not very good for applications where centering and accuracy are important.

Thanks man! I'm hunting for a tough micro servo for planks that will not break the bank! I believe that means it must be fairly accurate and reliable, huh?
get what you pay for? Must be some little exception????

I actually had good luck with the "SuperTec Micro 2BB MG Servo" (aka GWS?. I had a couple of those on the v-tail of an old tragi. There was no slop in the gears at all and they centred a lot better than the hitec servos that were in the wing. (i.e perfectly).

They were also pretty fast and rather powerful. I had a natural suspicion of them, being cheapos (not sure on the servos reputation either), but i have to be honest and say they couldn't be faulted. Maybe i was lucky (for a change!).

EDIT:- they also survived a crash which snapped one of the v-tail pushrods and caused the other ruddervator to bind on the tail while i ran to pick it up for probably over a minute.

DOUBLE EDIT: i believe they also recently survived the plane being nose dived into the ground from 300ft.... but that is just luck i fear!

These things happen if you try and fly f3f underground.

Nice specs, but it looks like they're a little thicker than even the HS-85MG.
That's why the HS-81MG is so attractive, because it's basically Hitec's
only truly thin (less than .5" thick), durable servo with decent torque. The
double centering problem and random electrical failures turned me off to
them years ago though. HS-65MG is the right size, has smooth/solid
movement, but has relatively low torque. How much that matters depends
on the application.

got a couple of those supertecs in my Zipper, doing the job fine, very important when you'd got that little movement for elevator

Try the Hitec HS65HB, no slop, great centering, not expensive and small. Resin gears seem very strong. I also find supertecs very strong.

I know R/C Junkie has been raving about the corona digitals in various sizes for good budget servos. Maybe worth an investigation?

I use these:

http://www.hobbycity.com/hobbycity/s...idProduct=3609

Same size as HS-85MG; they are fast, center perfectly, metal gears, less than $15 each. They are often incorrectly compared to the HS-81MG however they are actually the equivalent of the HS-85MG but have much more torque. I put these in for both flaps and ailerons for my molded planes and they work flawlessly.

Hmmm, impressive looking servo, smaller than an 85 but more powerful. Found a UK supplier and only 14!

I like the 65, the HB version seems to have the lowest slop of any of my servos and can be boosted with 6 volts.

Tony, there's virtually no perceptible slop in the gear train when you mount an arm and try to twist it. Any tighter and I'd be concerned about premature gear train wear. Nice thing about these is that they are so inexpensive, if you do break/wear out the gears, just replace the whole servo as they cost the same as replacement HS-85MG gear sets.
