need a servo horn that holds up

[wojin]

im tired of bending servo horns. both bending towards the servo and twisting sideways. i've been through 3 JRs and 2 from CKRC. so what are you guys using that holds up?

since you are gonna ask its a JR 8711, bending horns on axial and berg axles

yes i did search, went through a couple hundred posts and all i found was the robotronics that only looks beefier where the rod end bolts in and about the same in the arm

how thick are they and what are they made of?

[666]

Thick enough, 6061 aluminum. You will never have an issue. I have been running these hard on a HEAVY super for many years without failure.

Those look nice as well.

[wojin]

yah, thats the one i mentioned earlier. they dont look any stronger where im bending/twisting

[davidsc3]

One day I'll learn to read the entire post, sorry.

[wojin]

dont worry about it, im not here to bash you, lookin for advice like most of the others on here

I measured, 3.2 mm, trust me these are the beef, I guarantee it. You will rip your servo off or strip gears before you faze these.

[wojin]

over 3mm huh, thats the SWB one? might have to give them a try

If you bend the Robotronic servo horn your doing something wrong. They are very strong. I ordered mine from ebay and they were a little cheaper. I think I got 3 for less than $20.

[thatguy]

could it be the way your linkage is set up,or epas not adjusted properly?

[wojin]

its bending back from hitting stuff. twisting when its bound up

[wojin]

alright, i got the robotronics horn and it doesnt fit. JR 8711 servo and robotronics #23 JR horn. took the screws all the way out and tried prying the clamp apart... no luck. WTF

[JeremyH]

Are they the correct spline count?

The Robotronics are pure beef:

thats the one i got, says it for JR, hard to count the splines when some are cutout for the clamp

I thought the same thing when i got mine. They are just very tight... I had to use a little KY jelly and push like crazy, but it WILL fit.
