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

I just build a HPI Cyclone TC,and it's looks great,i use it for drifting racing, all carbon woven main chasis, shock tower, upper deck, and all aluminum support for riggit rc car, check it out.

using :
brushless drift motor 17T
spur 99T
pinion 42T

very fast in cornering, and straight track, make this kit a killer in drifting at tight and long drift.
