Problems

• (List of Problems, 1 per bullet point)
• screws did not have enough contact, too shallow threads
• tolerances between shaft and ball bearings resulted in shaking that caused screws to come out
• large regions of useless aluminum on side plates
• back plastic armor affected wheel contact
• screws on hub (4-40) too thin to handle impacts
• open access to electronics by spinning weapon
• small bearings

Good aspects

• low friction between axle and hub

Changes/Improvements
