Not quite sure what you mean by "Doing the throttle" Do you need help with the cable, servo throw, or what exactly. As far as mounting I guess I am with everyone else, I have never had an issue with the supplied servo hardware. I would just recommended that you mount the servos as per the radio manufacturer's instructions.

Might I recommend that you get the plane looked at by an experienced builder in your area to check it over. I did this when I was starting out and it was well worth it.
