• FingerTech's new Lightweight Twist Hubs are great for 1lb antweights all the way down to 150g robots!  Made from injection-molded blue glass-filled nylon for high strength and extremely low weight.

• Twist Hubs easily and securely mount FingerTech Foam Wheels. Foam wheels are the preferred choice for combat robots because they absorb impacts and save your drive gearboxes.

• The foam tire is held tightly by a custom locking washer that won't release unless pressed in and turned 90 degrees.

• The hub is secured to the motor shaft by a strong 8-32 setscrew.

• 3mm shaft bore fits our Silver Spark Gearmotors and most other common small robot drive motors.

• Currently available only in Wide thickness for 0.75in thick foam wheels.

Nov '24: New and Improved! Now includes a metal threaded insert so you can really crank down the setscrew AND add threadlocker, and stronger washer indentations so pliers don't punch through.

- FingerTech's new Lightweight Twist Hubs are great for 1lb antweights all the way down to 150g robots! Made from injection-molded blue glass-filled nylon for high strength and extremely low weight.
- Twist Hubs easily and securely mount FingerTech Foam Wheels. Foam wheels are the preferred choice for combat robots because they absorb impacts and save your drive gearboxes from damaging strikes, while being lightweight and sturdy.
- Lengthwise fins ensure the tire cannot spin on the hub even if the washer isn't installed.
- 3mm shaft bore fits our Silver Spark Gearmotors and most other common small robot drive motors.
- Lightweight Twist Hubs currently available only in Wide thickness fitting 0.75in thick foam wheels. (If you would use 0.50in for thin wheels, email us so we can gauge interest!)
- These are the hubs that come with the Viper Combat Robot Kit.



Specifications:
- The hub is secured to the motor shaft by a large 8-32 setscrew driven through an aluminum threaded insert. Feel free to tighten these with gusto!
Keep in mind this is plastic (very strong, but still not as strong as aluminum) - the setscrew does not need to be overtightened. "Firmly snug" is enough to hold the wheel tightly on the flat of a motor shaft.

- 3mm bore fits our Silver Spark gearmotors and most other common small robot drive motors.
- Weight: 3.7g each. (7.4grams per pair) Super lightweight! (Half the weight of the aluminum Twist Hubs.)
- The foam tire is held tightly by a custom locking washer that won't release unless pressed in and turned 90 degrees. See installation video below.
- Four protruding fins will allow you to keep driving even if the locking washer is destroyed. No tire slippage!



 Requires:
- 5/64in hex wrench
- Foam wheels (FingerTech Foam Wheels, or hobby store Lite Flites)
- FingerTech Twist Hub Key or needle nosed pliers
