MORE ABOUT THE VERTICAL SPINNER POLYCARBONATE TOP ARMOR:
What it is / Who it’s for
The FingerTech Viper Vertical Spinner Top Armor is a polycarbonate replacement panel for FingerTech’s Viper Vertical Spinner Add-On and our Weaponized Vertical Spinner Bundle. This cover is designed specifically for that add-on. This top cover is perfect as a spare or event-ready backup. With a precise fit for the spinner configuration, it balances durability and weight while protecting your Viper’s internals from debris and overhead strikes. This is the latest revision (see Revision Control below) and matches V-Spin Rev 4 (April ’25 and newer).
How it works
The polycarbonate top armor mounts above the chassis, pairing with the UHMW Vertical Spinner front panel for complete protection. At 1.6mm (0.063in) thick, it provides a rigid, lightweight barrier against weapon impacts. While not as impact-absorbing as UHMW, polycarbonate resists shattering and keeps your robot agile, making it a reliable choice for replacement or travel spares.
What’s included / What you’ll need
The package includes one pre-cut polycarbonate top armor panel. Installation requires basic hand tools. Depending on your build, you may need six 6-32 button head screws (not included). A 5/64in hex wrench is typically required for standard hardware. Align the panel carefully with the spinner cutout to ensure full clearance and a secure fit.
Why this part?
Polycarbonate armor keeps your Viper light, responsive, and competition-ready. Because tops can take repeated hits or wear from overhead strikes, having spares ensures your robot won’t miss a match. The UHMW Vertical Spinner Front Armor complements this panel for a complete defense setup.
REVISION CONTROL
FingerTech Robotics has revised their Vertical Spinner Kit, and this armor aligns with that update. If you have trouble fitting the cover, see the downloadable drawings for potential modifications. This cover is Rev 4; the previous revision is R3. See the drawings under PRODUCT DOCUMENTS or in the gallery for both R3 and R4. Unfortunately, R3 is no longer available from FingerTech. If you need an R3 cover and have no printing capability, please email us at info@itgresa.com and we will see if we can print one from TPU.
Safety & best practices
Inspect the top armor regularly for cracks, bends, or stress marks, especially after hard fights. Replace panels as needed to maintain structural integrity. Always tighten all fasteners before operating your robot.
Installation
Installation is straightforward: align the panel with the chassis and fasten using six 6-32 screws. Confirm your Vertical Spinner revision matches this cover (Rev 4). Ensure the cutout clears the vertical spinner weapon and that the screw pattern is aligned correctly.

Is THE Viper Vertical Spinner top armor upgrade compatible with other Viper Add-Ons?
No. The Vertical Spinner UHMW Front Armor is designed only for the FingerTech Viper Vertical Spinner Kit.
It is not compatible with the: Viper Combat Robot Kit, Lifter Add-On, Horizontal Spinner Add-On, or Tail Spinner Add-On. For those builds, use the standard UHMW front armor.
How does UHMW compare to polycarbonate in durability?
UHMW is more impact-resistant and lighter than polycarbonate, helping your robot stay agile while providing stronger defense against weapon hits. "UHMW's light weight compared to steel, along with its high resistance to wear and abrasion, made it the perfect material for the robot's armor. Unlike steel armor, which does not absorb impacts well and will not stop the robot from moving when hit, UHMW armor can absorb the impact of an opponent's spinning blades." - Interstate Plastics website
What tools are needed for installation?
Basic hand tools are required. Standard mounting uses 0.50" 6-32 screws with a 5/64in hex wrench. Additional hardware may be needed depending on your robot’s configuration.
How should I maintain the armor?
Inspect the armor regularly for cracks, gouges, or loose mounting points. Tighten screws as needed to ensure consistent performance and protection in competition.
