- Pivot drive repeatedly jammed (drive jam, not steering). Problem appears to originate with the wheel axle collar, some of which cannot be tightened securely. When the collar moves, the wheel shifts on the axle. The wheel shift causes the chain to jam on the 9T sprocket, which is not chamfered. Sometimes the jam is momentary. Sometimes not. One such jam led us to change a pivot on Thursday, another unfixed one effectively disabled us in the semifinals. A few more likely froze us at different times in qualifications, once getting us stuck in an opponent's lane causing a penalty. Since the jam stalls a CIM motor, these jams run down our batteries extremely quickly.
- Post-FLR, problem resolved by fitting removable spacers in the gap between the collar and the jam nut.
