Just Cuz Robotics Chonk Key Blade

Just Cuz Robotics Chonk Key blade- a weapon designed for the JCR-4936 “Cherry Bomb” motor.

We present Just Cuz Robotics Chonk Key blade, a beetleweight level (or greater) weapon specifically designed for the Just ‘Cuz Robotics JCR-4935 “Cherry Bomb” motor. Built of AR500 steel, this dense, heavy blade is 1/4″ thick and was designed for combat robotics with an integrated shock absorbing system. The blades were used on Subtraction at NHRL Teams and proved durable and powerful. The Chonk Key has a 7.5″ effective diameter and a stocker large cross-section to prevent bending from extreme out of plane hits. The Long Bar is the king of reach, with a 9″ diameter, and symmetrical design. Both of these blades will require our custom blade mount shoulder bolts and 3D printed TPU shock mount for use with the motor. These blades are around 230 grams. Keep in mind though that the Long Bar on a JCR-4935-1000KV motor will reach crazy max tip speeds of well over 300MPH even on 3S, so it is not recommended for higher than 3S voltage! The blade needs to be used with a 3D printed spacer (included with purchase) so it fills the 0.2″ width required for the 5022 motor. See Product Documents for an STL file.

Made from super durable AR500 steel, the same that shooting targets are made from, this blade is built to last and dish out some serious damage.

Note: The Chonk Key blade has sharp edges! Be careful when handling.

You may find due to tolerance variations between weapons and motors, some filing or Dremel grinding is needed for the perfect fit to the motor.

Includes:

• 1X Chonk Key AR500 weapon blade hubmotor weapon

• NOTE: Shoulder bolts are NOT included due to potentially different mounting designs.
