Default Common sense mg645 servo

I need to know if anybody has run this servo common sense mg645? an what type of horn are you using? I tryed all of my servo horns aluminum an plastic, found a plastic tower hobbies but instantly stripped it , it has metal gears an seems to have decent torque, did the search forum but came up with nothing, any help out there?

i ran that servo on my crawler for a while until it went through two sets of gears.... just wasn't up to the task. I used a 24T aluminum arm from my local hobby store. IIRC all the HiTec servos have a 24T gear to attach the arm on. Plastic will just strip out as you found out.

Ill give that a try , thanks,this is going on my scaler so not too much binding in tight spots like my comp rigs, the servo was a freebie but didnt have a arm with it, a futaba fit but was plastic an was kinda loose also, Ill give a hitec arm a try tonite.

Good to know.

Yes, I will either do a new thread with mini/micro servo splines, or add to existing.........
