No matter how much you plan, sometimes things just don't work the way you hope. Editing and redesigning is a normal part of any creative endeavor.
Last year, we attempted to make two sets of mechanized, flying ghosts using a brushless model airplane motor and a custom designed propeller blade, created on a 3D printer. Unfortunately, there just wasn't enough power to move the blade.
This year we've increased the power source, upgraded the motor, and swapped out ghosts for lighter-weight bats!!
