Servo Standards?

Hey all,

Just graduated from college and started a new job. I finally have time to pursue projects I've always wanted to do.

ANYWHO. I bought a cheap aluminum hexapod frame from the internet that recommended I use Tower Pro MG995 servos. Unfortunately I just found out through online reviews that these servos and their improved models are not so hot, to put it extremely lightly.

I noticed however that a Futuba S3003 I had lying around seems to have a casing with mounting holes that fit flush with the holes in the frame as well.

Yahmez I hear you know someone, who knows someone.. Well I just have a question..

So I hear you have a good source for faulhaber motors, and I'd like to hear which kind of motors you're able to supply and the cost + shipping cost to Denmark..

and I just wanted to say Fantastic Work Junkster and I think a little Bragging is in order.
