My 2018 competitor, with a titanium horizontal blade from FingerTech Robotics. I felt like rebuilding a drum spinner twice is too boring so gotta change up the weapon choice every year.

I was the winner of that fight because of the driving I did after my blade broke off. My radio is a FrSky Taranis Q X7 and it has adjustable curves for everything, so I actually had better driving control, better than most other competitors.
The steel shaft of the motor is the problem, apparently a hollow steel shaft isn’t hard enough to handle the impacts. The next video shows the second time the motor shaft broke. I did actually stick a #4-40 steel bolt into the hollow part, it may have made the problem worse, this time instead of just the shaft snapping, the entire plate holding the bearing shattered.
