Task Description
Find a servo and compatible Gear train with bearings that can rotate the hex shaft (pitch).
Constraints
To be written by the Project Manager. All constraints should be their own row of the table, if a constraint is removed it should be crossed out but left in the table. The append date is when the constraint was last updated (update this when constraints are removed!) DELETE THESE INSTRUCTIONS BEFORE PUBLISHING

GEAR ALIGNMENT SPACER ADDITION
Due to imperfect bends in the plates mounting the servos, severe gear misalignment is occurring. To solve this I have added a spacer to correctly space the tops of the plates so the gears mesh properly.
