What servo horn?

[throttlejock27]

Looking to get a servo horn but don't know how many tooth number to get with this servo. And will I need a long or short? I was looking at the robitronic arms. Thanks

HiTec RCD HS-645MG High-Torque 2BB Metal Gear Servo

Hitec servos have 24t spline shafts. The length to the mounting hole on the stock servo horns is 20mm.

The Robitronic RBOR17002 or Axial AX30835 would work.
