FingerTech NightWing Titanium Weapon Disc
FingerTech NightWing Titanium Weapon Disc
The FingerTech NightWing Titanium disc is the premium upgrade weapon for the 3lb undercutter class — same four-tooth geometry as the battle-proven AR500, cut from Grade 5 (6AL-4V) titanium for faster spin-ups and better control. At 172g it’s 45% lighter than the standard AR500 disc, which means more agility and quicker weapon recovery without sacrificing the destructive reach of a 10in undercutter. Also available as the standard AR500 disc.

The NightWing Ti Disc
The FingerTech NightWing Ti disc is the premium upgrade weapon for the FingerTech NightWing Kit — same devastating 10in four-tooth geometry as the standard AR500, cut from Grade 5 (6AL-4V) titanium. At 172g it’s 45% lighter than the AR500 disc, which translates directly to faster spin-ups, quicker weapon recovery, and more agility in the arena. If you’re competing seriously with a NightWing, this is the upgrade disc.
Grade 5 Titanium — Why It Matters
Grade 5 (6AL-4V) titanium is the aerospace-grade alloy used in high-stress structural applications where strength-to-weight ratio is critical. For a 10in undercutter disc, that means you get a weapon that spins up faster, recovers quicker after impacts, and carries significantly less rotational inertia than the AR500 version — giving you more control over your weapon speed and timing. The trade-off versus AR500 is raw hit weight, but in the hands of an experienced driver the Ti disc’s agility more than compensates.
Four Teeth, Optimized
The disc’s four-tooth geometry is identical to the AR500 version. Tooth rake and relief angles have been optimized by FingerTech for the ideal balance of bite and durability — aggressive enough to catch and launch opponents, tough enough to survive the hits that come back. The undercutter profile keeps the disc low to the ground, sneaking under opponents’ armor where it does the most damage.
Compatible Mounting Options
The Ti disc uses the same 4-hole screw and slot pattern as the AR500 — fully compatible with the FingerTech Blade Mount, the FingerTech 60T Weapon Pulley, or your own custom hub. It’s a direct drop-in swap for the standard disc.
Stock a Spare
Ti is tough, but combat discs take hits — that’s their job. Having a spare NightWing Ti disc in your pit bag means you’re never caught out at an event. Pair it with a spare FingerTech 67T Timing Belt and a FingerTech Safety Clamp and you’re ready for whatever the arena throws at you.
Safety Warning:
Spinning weapons generate extreme kinetic energy. Always engage a weapon lock and test only within a secure arena or test box. Never operate a spinning weapon in an unsecured area.

Is this a drop-in replacement for the standard AR500 disc?
Yes — the Ti disc uses the same 0.75in bore and 4-hole screw pattern as the AR500 version. It's a direct swap with no modifications needed to your NightWing or custom undercutter build.
Ti or AR500 — which should I choose?
It depends on your driving style. The AR500 disc is heavier — more stored energy at speed, harder hits. The Ti disc is 45% lighter — faster spin-ups, quicker recovery after impacts, more agility. Experienced drivers who want more weapon control tend to prefer Ti; builders prioritizing raw destructive power tend to prefer AR500. Neither is wrong.
What hubs and pulleys does this disc mount to?
The disc is compatible with the FingerTech Blade Mount, the FingerTech 60T Weapon Pulley, or your own custom hub. Mounting uses 4× 6-32×3/8in button head screws.
How often should I replace the disc?
Titanium is extremely tough but inspect the disc after every event. Look for nicked or chipped teeth, visible bending, or any wobble when spinning. A damaged disc affects both performance and safety — don't compete with a disc you're not confident in.
