Are the output shafts/splines on the small Hitecs (e.g. HS-85MG) the same as their normal size servos?

I am looking for a decent horn to replace the relatively flimsy stock horns.

Try Servo City. Here is the link...

One link is for all servo arms they sell and the second one is for some heavy duty DuBro arms that fit the HS-85. I have used these before on other Hitec servos and they work well.

I did a fit check between an HS-81, an HS-225 and an HS-5645MG and the splines are the same on all three. It's only an assumption on my part but the HS-85 probably has the same output spline as my HS-81. A quick phone call to HiTec ((858) 748-6948) will comfirm my findings.
