i was just installed some awesome hop ups,
i bougth it from 3 racing :
- super gear adapter (purple)
- 18 T pulley aluminium (purple)
- front knuckle aluminium (purple)

result: more speed on lower torque, longer run time on same battery, more control, make the cyclone more rigit.no more vibration from the normal plastic pulley, so the car more stabilize.
smoother turn and get more speed on the apex, it's very suitable for speed drifting.hoping i can post some video next time
