Thank you very much! I ordered some screws. I appreciate the help!
As for the steering, I don't think it is the servo saver, because even with it tightened all the way down, it doesn't want to turn, and my servo horn broke because it pushed so hard but wasn't able to move anything. By hand it seems to turn OK when disconnected from the servo, but maybe I am just not sure how it should feel. I am quickly getting used to how easily everything seems to work on my Lightning.
