Product Overview

The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (thermoplastic polyurethane) with a 80A durometer hardness. This robust but lightweight wheel provides good traction on carpet and soft tiles. The Stealth wheels are the perfect wheel for intakes and other auxiliary robot mechanisms.Two bolt circles are included on this wheel, with an inner bolt pattern designed for use in FTC applications and the outer pattern designed mainly for FRC uses.

Product Usage:
Many thread locking materials are not compatible with polycarbonate and can eat away at the plastic. Be sure to check which adhesives are okay to use with this product. This link will allow you to check which materials are okay to use with what adhesives, https://bit.ly/loctitematerialcheck

Usage:
Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel.

With Axle and Hub:
  • These stealth wheels have an integrated hub matching that of current Tetrix wheels. This means existing tetrix hub can be used to mate this wheel with a shaft.
With Sprocket:

    Excellent quality and service

    These 4 inch wheels worked great for us during our second FTC competition this year. We were able to have more grip to the playing surface which allowed us to push more blocks around the field.

    Great wheels

    Great wheels. very good grip on FTC floor pads. A bit quick to break traction on ramps. Probably not appropriate for the mountain in the Res-Q challenge unless you have a way to appropriately center weight to maximize traction

    Good wheels

    only issue was dealing with the extra thickness of the wheel at the bore. Need extra long screws to get through it. Other than that, pretty great wheels, way better contact surface than others.

    Consistent And Sticky

    ADVANTAGES: When I first ordered these wheels, our team was still using the stock Tetrix wheels, These wheels make a world of difference, these wheels slip along the mat surface much less, making autonomous programming much easier and more consistent. When on the field at competition, these wheels give you the advantage even on heavier robots when push comes to shove. DISADVANTAGES: These wheels are sticky enough that they have killed two of our Tetrix motors when the bot inevitably runs into a wall during autonomous, not a serious issue if you are using the NeveRest motors though Overall a very good buy for only $6 per wheel.

    "Awesome for FTC!"

    "We bought a set of these for our FTC bot. They do require a tetrix hub and some longer screws and you will need to tap a bronze bushing into the outside of the hole for the axle, but once you do those things, these wheels a bulletproof. They are very sticky and since the tread has a flat profile, you get a lot more contact with the mat (translation, hard to push around...) I would easily recommend these over the Tetrix wheels...unless you might be competing with us....then go with the Tetrix wheels.... Seriously, just buy these."
