Default Quick Ace servo question

Anyone running the Ace servos...what's the spline count? I'm planning on ordering one and wanted to pick up an aluminum servo horn, but don't know what it compares to.

Thanks,
David

Futaba 25 spline is what you need.

A spline is a shaft that has grooves machined down the length. Almost like a gear, but it's designed into the shaft. So the splines on the servo output shaft must match the splines on the servo horn. This way when the servo turns, it will turn the servo horn also.

Damn, I wouldnt even bother trying to take apart and fix a servo, id just buy a new one.

And thats the term I was looking for, the servo horn... I have a Hitec servo and the servo horn is smaller than most... I put plastic servo arms on it and it works fine for a few mins, then wears itself out and strips. Or if I hit something that causes force on either one of my front tires, it will instantly strip it!! What kind am I supposed to use? I want a metal one but im not sure what to buy, and should the screw just screw right into the metal arm or does it need a nut at the bottom?

Thanks

Hitec uses there own servo horn count. I think it is like 23. There all on there own on this. JR, Airtronics, and KO servos all have the same spline count. Futaba and Hitec use a different thread count and aboviously the futaba is a 25 spline but the hitec is something different.

Do the rebranded AE servos take the same Futaba 25 spline horns?

Yes. They are the same servos as the ACE servos, which are all under the Thunder Tiger name I think. These servos are awesome and very tough.

I have a Hitec 625MG
The HITEC 5955 tg dervo is top of the line. Get an aluminum horn and your set. Make sure to set your radio right so you don't blow your servo. The ace1015 is top too. I run the ace for throttle and hitec for steering
