Hitec HS-7950TH servo horn?

[Rumpelhardt]

Could some one please tell me the tooth count for a servo horn for a Hitec HS-7950TH servo? Got a couple coming for my Wraith and Yeti and need to make sure I have the correct parts.
Thank you.

24t and 2.6mm screw.

Thanks

The 2.6mm screw part is important. You can't really tighten the included Philips head bolt, and cap head Allen drive 2.6x10 bolts are a nuisance to find.

And don't let someone in you LHS tell you to use 2.5mm because that is what they have and it's "close enough". HPI has a Cap Head M2.6 x 10mm, part number Z422. I've also used the Axial M2.6 x 8mm without any issues when using the Axial aluminum servo horns.

Thanks for the heads up on the screw.

would this work?
Axial Racing AX31538 Hex Socket Button Head M2.6x10mm Black (10) | eBay
AX31538 part number

It likely would. It doesn't list a thread pitch. The picture shows the proper fine machine threads, but the only axial 2.6 bolts I've personally seen were coarse thread, like the ones holding wraith body panels on.

Either way, I prefer a cap head bolt to take advantage of the larger driver size. Plus, IMO, axial hardware is soft, like hardly grade 8.8 if we're lucky. Good bolts will be marked 10.9 or 12.9.

Thanks for the Hpi #. Bought a pack before they go out of stock.

24t and 2.6mm screw.

Yes! "thumbsup"

2.6x8mm, iirc 2.6x10mm might work, got mine and some matching washers at www.mcmaster.com
As stated much higher quality than most Axial screws, 10.9 and 12.9 rated.

Think I"m using the 10mm length in my servos.
