Hi Guys,
Can these brackets (lynxmotion.com/images/html/build131.htm) where do you get ball bearings from?
Thanks!
Nope… been there my friend.

You get what you pay for with servos. There is no free lunch.
Oh, thanks. Do you know where I could get some one for tower pro? Thanks!
Acutally just checking, the servos and basically the same, less than a mm out at the most, so are you sure? Has anyone actually tryed it?
i know…
**Specifications: MG995 **
Dimensions: 40 x 20 x 36.5mm
**Specifications: Hitec standard size (hs645mg) **
Dimensions: 40.6 x 19.8 x 37.8mm
Still they wont align correctly nor do those servos perform correctly. Poor centring, lack of real torque, reverse pwm (although thats not really an issue but…)
One thing i havent tested is the horn. is the servo shaft the same as hitec and will it except the same horn with hole pattern? never the less, they still wont fit/work well.
there are brackets available for those servos but thats something you will have to source yourself ()i cannot add link) as they will be a cheap knock off copy of the true lynxmotion bracket.
again you will not get a very good.
… . .
OK thanks, while we are on the topic does anyone know of any other decent servos with around 8kg/cm which are decently priced? £22 is so much money for one servo!
Hobby king has an analog servo 9225000014 that has close measurements to the hitec servo, and has metal gears, ball bearings, and Torque: 10kg.cm (4.8v) 12.8kg.cm (6.0v). Might be worth a look. You could get a couple to build a test leg to see how well they work.
I totally agree that servos are expensive especially when you need 12 - 18 - or 24 of them.
But you do get what you pay for with servos and with that comes a price to match. And in all honestly £22 for one servo really isnt that much. but yes it does add up.
the HS-645MG servos are (for me) the most reliable for these kind of assembly.
At 6.0V they Will give out 133.31 oz/in. (9.6kg.cm).
Looking on ebay etc or buying them from an outlet will range between £15-35.
I managed to find some 645’s for £10 and some for slight more. but i got lucky.
But again you do get what you pay for.
This all depends on the robot you are making.
If you tell us the type of robot you are making … along with its construction material, then we may be able to find a lower torque servo with a smaller price that will fit and work correctly.
But if it is the Phoenix you are after then im sorry but the 645’s will be needed.
You may even get away with swapping the Hip Joint (Coxa) for a HS-485.?
All round its an expensive hobby but one that i find is affordable over time.
