[JonBoy]

I have a hitec 645MG servo and was wondering if it was the same size servo arm at Futaba, JR, or Airtronics? i need a arm and associated sells a set of the 3 and was wondering of any of them would fit?

If you are talking about a servo horn (the thing that connects directly to the servo and is attached to your steering linkage), then you would need a specific one for a hitec servo. The top of the servos have different teeth count on all the different brands. Hope this helps.

One of the three should fit, 24 splines I think.
