Thanks for the feedback guys.

Seems to be I should:

1. Try to make the connections with less drag (again, not sure how much I can do here given the pushrods and housing are pre-placed for me). Does anyone use a lube like Tri-flow in the pushrod housings ever to reduce drag?

2. Don't worry about the buzzing too much - they all buzz. Just don't want to be driven crazy by it and don't want to run my batteries down prematurely.

3. Maybe by a beefier servo.

Am I missing anything?
