Going along with this whole "first-second" thing, I'd like to present:

Features:
-Ability to hold 5 quaffles in the hopper, up to 7 balls total
-Ground collection compatible with quaffles and bludgers
-Potential for human loading, just need to change the hopper a little
-collector articulates up to allow balls up into the shooter elevator
-6x 4" custom traction wheels driven by 2 2 CIM custom gearboxes geared for 5.5fps and 16fps
-Anodized black for superior performance
Just like RI3D, very unrefined but demonstrates the concept.
