servo troubles
 

So tonight I was driving my sakura d3 cs and it slid inyo a chair and messed the servo up.. changed it out for another servo in my hpi nitro and the turning isnt as sharp.. so I ordered another tower hobbies servo.. comes with universal arms to change out.. but how do I get the new arms back on? Seems like the hole is to small for the splines.

There are different spline sizes. 25,24, and 23 tooth to be exact. Make sure you are using the one that matches your servo.

Yes its the same arm that came off the servo and wont go back on..
What servos do yall usually run? That has a great turning radius.. my note 2 wont ket me search the forums.

Servos usually have a 60 degree left 60 degree right speed, or 120 in all.

ill take pics of full turns tonight and see if they seem right.. like i said im new to this hobby so im kinda walking in blind as a bat. and thanks panda for helping me.
