Thanks Cod,It's a mini-servo so the holes are pretty small...drilling is absolutely an option, I am just afraid to crack the thing. I've never seen holes this small on anything (and neither had ace) so I might give up soon. Is there a name for these? I thought they might be called mounting holes or something but that just pulls up the screws for mounting the servo to a bracket where I'm just trying to mount a piece of metal to the horn.To be honest, I'm just waiting for someone to tell me that I'm doing something stupid, because I feel like this should not be so difficult. I'm not the first person in the world to use one of these servos so you'd think there's be an obvious screw size to fit through the holes on the arms.
