This is a great idea guys and best of luck sorting it all out, but i have the faith in you all to do it. I see how well you handle the task at hand. Just a few questions i hear but do not think i saw.

What is the "buzzing sound" my servo is making?
How many props should i get and wood or "plastic"
How many rubber bands should i use? (why shouldn't i criss cross them?)

if i think of more i will chime in. Thanks
