Looks like that should work Kevin, one thing you might consider is the vibration effects on the nylon clevis which has a very small pin in it, (speaking of the throttle) it's a good place for a ball link with a safety washer on it to prevent it from ever coming off, a piece of cable with it's flexability might be a better choice connected to an easy connector at the throttle arm, it's very easy to adjust also. I solder a good inch of the cable where it goes through the servo connecter, it helps to prevent slippage and cable frays.
Just an idea to kick around.
